• Very poor SCSI hd performance on IBM x336 with LSI 1030 RAID1

  - by David Tschoepe

  I'm experiencing very poor performance on an IBM x336 server with dual 73GB 15k hard drives on a U320 controller, LSI 1030. We're getting maybe 3.5MB/sec max (per HD Tune utility). It should be over 100MB/sec at least, I would think (another x335 box is running 70-80MB/sec). The server was recently setup and didn't really notice the problem, but may have been there from the beginning, so not sure. I have installed the IBM ServerRAID Windows utility. The server is running Windows 2008 R2 Web edition (if that matters). I thought maybe one of the drives was bad, so far I have removed one of the drives out of the array and tested again, but still the same results. I'm waiting for the RAID1 to resync and I will try pulling the other drive next. I've also used the ServerRAID utility but haven't noticed anything in there that might indicate a problem. Not sure if I'm on the right path here. So looking for some advice to track this down.

• Speeding up Outlook Express on Windows XP over satellite

  - by John

  My brother is in the field with Doctors Without Borders. I'm posting this question on his behalf. We use outlook express (on a pc running windows XP) and a 9600 baud dial up satellite phone modem to get our email direct from the server in Paris. As this is a very expensive way to communicate (our satellite bill is $50K a year, no joke), it seems like trying to streamline is a good idea. Here's the question- when we connect, the sequence goes: Send outbox mails. This goes pretty quickly, probably 10-15 seconds for each email, up to maybe a couple minutes for an email of 150k or so). The status bar moves pretty quickly, according to the emails sent. The system then says "Checking for new messages on (our account name), and "Receiving list of messages from server". This takes a long time. Like 10-15 minutes. The status bar crawls along. Then it receives the messages. "Receiving messages from server". Again, each message takes 10-15 seconds, and this part moves along reasonably fast. I'm curious as to what is going on in the second part. It takes forever, and doesn't seem to be part of the sending or receiving messages themselves. Is there a way to speed up the process by changing a preference with communicating with the server or something? Does anyone have any advice for him speeding up what Outlooks Express is doing? Obviously his software is ancient and adding more software is not realistic based on the connection speed. Thanks!

• EEE PC dropbox server running 24/7

  - by microspino

  I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have Samsung SCX 4521F (fax/print/scan/copy), Samsung ML2010, HP Laser jet P1006, HP Color Laserjet CP1215, HP Office jet pro K8600, HP Design jet 500. All of them now are connected using little print servers and I want to get rid of them hooking everything to this mini server. The fax/print/scan/copy machine need to stay connected to a PC to make me able to use the software that comes with It. The mini server would save me on this too. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: If You have something similar running for a long time If You disagree with this hardware choice and If You would suggest some other device. If You see any issues with my printing setup Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

• Defeating the RAID5 write hole with ZFS (but not RAID-Z) [closed]

  - by Michael Shick

  I'm setting up a long-term storage system for keeping personal backups and archives. I plan to have RAID5 starting with a relatively small array and adding devices over time to expand storage. I may also want to convert to RAID6 down the road when the array gets large. Linux md is a perfect fit for this use case since it allows both of the changes I want on a live array and performance isn't at all important. Low cost is also great. Now, I also want to defend against file corruption, so it looked like a RAID-Z1 would be a good fit, but evidently I would only be able to add additional RAID5 (RAID-Z1) sets at a time rather than individual drives. I want to be able to add drives one at a time, and I don't want to have to give up another device for parity with every expansion. So at this point, it looks like I'll be using a plain ZFS filesystem on top of an md RAID5 array. That brings me to my primary question: Will ZFS be able to correct or at least detect corruption resulting from the RAID5 write hole? Additionally, any other caveats or advice for such a set up is welcome. I'll probably be using Debian, but I'll definitely be using Linux since I'm familiar with it, so that means only as new a version of ZFS as is available for Linux (via ZFS-FUSE or so).

• Updating modules on VPS hosted under OpenVZ

  - by tertle

  Been trying to install OpenVPN on a VPS but come into a few problems when trying to start the openvpn server: Service deferred error: IPTablesServiceBase: failed to run iptables-restore [status=1]: ['FATAL: Could not load /lib/modules/2.6.18-028stab070.14/modules.dep: No such file or directory', 'FATAL: Could not load /lib/modules/2.6.18-028stab070.14/modules.dep: No such file or directory', 'iptables-restore: line 46 failed']: internet/base:1175,internet/base:752,internet/process:45,internet/process:306,internet/_baseprocess:48,internet/process:775,internet/_baseprocess:60,svc/pp:116,svc/svcnotify:26,internet/defer:238,internet/defer:307,internet/defer:323,sagent/ipts:105,sagent/ipts:39,util/error:52,util/error:32 service failed to start due to unresolved dependencies: set(['user', 'iptables_openvpn']) service failed to start due to unresolved dependencies: set(['user', 'iptables_openvpn']) service failed to start due to unresolved dependencies: set(['iptables_openvpn']) Anyway so after a bit of playing around and some advice, I found that the Linux kernel and modules don't match on my server. uname -r returns 2.6.18-028stab070.14 and ls /lib/modules returns 2.6.18-028stab070.7 The server is running OpenVZ and my container uses Ubuntu 9.10. So my question is, is it possible for me to update my modules on a VPS and if so how would I do this, or is this something I'll need to try get my host to do? Thanks in advance.

• OS X Hard drive recovery

  - by Adam

  I am trying to recover data from a bad Seagate 1TB hard drive in a 2010 iMac. One day the iMac wouldn't boot (stuck at gray screen on startup). I removed the hard drive from the iMac and connected it to a MacBook using a 3.5" HDD to USB adapter. The hard drive wouldn't mount but it did display in Disk Utility that that there were 2 partitions on the disk. I tried to run Disk Warrior and it showed thousands of errors but still wouldn't mount. At this time the hard drive only show one partition in Disk Utility. Next I tried putting the hard drive in a desktop PC and running Spin Rite - which then gave me several division overflow errors (even with running Spin Rite with a newer version of DOS). The SMART status on the drive reports that the drive has had failures and HD Tune referenced the drive had once hit 59 degrees celsius. Disk Utility gives me the following message when running a pair: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. Overall, the hard drive spins up and sounds OK - there are no clicking noises but the hard drive won't mount and displays as a light gray "Macintosh HD" in disk utility. Any tips or advice on how to recover data on this drive would be GREATLY appreciated! Are there any other tools I can try before calling it quits on this drive? Thank you

• What are the disadvantages of domain email forwarding?

  - by naivedeveloper

  I have a domain, example.com. My domain registrar gives me two options concerning email. Set up forwarding email addresses (e.g., [email protected] forwarded to [email protected]. Set up Google Apps for email management Thus far, I have gone with option 1. I have a generic GMail email, [email protected], and I subsequently set up various email addresses on my registrar to forward to this gmail address: [email protected] -> [email protected] [email protected] -> [email protected] [email protected] -> [email protected] Through the GMail account, I have the option to alias these addresses when sending email. For example, from [email protected], I can "send email as" [email protected]. That way from the vantage point of the receiver of the email, the email came from [email protected] as opposed to [email protected]. My question is: Are there any disadvantages of this approach? Are these emails more susceptible to being picked up by spam filters vs using the Google Apps approach? Is there any hidden indication that the email is being aliased? When viewing the email headers, it shows the email was sent from [email protected] and not [email protected] or "forwarded from [email protected]" or anything like that. Am I naive in assuming that my cheap approach to email is masked by aliasing my outgoing emails? I have chosen approach number 1 simply because of the ease of setup. With that said, are there any advantages of going with approach 2 (the Google Apps approach)? Thanks for suggestions and advice.

• TV-out worked, now doesn't. May the problem be the cable, TV, driver, OS, graphic card?

  - by Petruza

  I have a CRT TV hooked to the PC, which once worked great, now doesn't. I can't consider getting a newer TV, this one is used in an MAME arcade cabinet so it has to be a CRT for best old school look and feel. It's connected through the TV-out connector of my graphic card. When it worked, I had Windows XP, the same PC and the same card. Now I have windows 7, not sure if the OS switch caused the malfunction as I don't use the TV-out all the time. Can it be an upgrade of the Nvidia driver? I thought it may be the S-video to RCA cable, but tried 3 different cables and neither worked. In fact, one of them, that unlike the other two, has a single RCA output connector instead of two, behaves differently, although it doesn't work, but it does the following: When I open the NVidia settings panel, or when I change a setting and click Apply then the TV flashes for a split second and you can see the windows screen, but then it goes back to blank. So any clues what can be failing here, and some advice? Possible failures, please comment on the one you suspect the most: NVidia driver version Windows version Cable Graphic card's TV out other?

• Should one have a separate user account for work use? [closed]

  - by Tyler Wayne

  This question examines the practice of using a separate OS-level user account to divide work use from personal use (specifically, in a creative profession and on a personal computer). I recently left my in-the-flesh job to go to school, but I'm carrying on with the work remotely. I do all of my work on my laptop, and I currently have a separate user account called "Work" where I do exactly that. However, I'm now starting to question that practice. Because my hobby is the same as my job, I want to save notes of the things I learn while working. Because ideas come at any moment, I often want to throw something into my personal task manager's inbox and look at it again later. That task manager is well-suited to handle both the work and personal aspects of my life. Only my personal account has admin rights, but work sometimes requires me to install programs. My employer has no preference regarding my choice, so that is a non-issue. My work is essentially freelance web development, so advice given with that in mind will be much appreciated. Back up all opinion with some personal experience, please. Ideally, give a list of pros and cons and then name reasons for your position.

• sql 2008 disk layout on a budget this is for database mirroring

  - by user22215

  Guys I'm rolling out a SQL database server that will be used to back Sharepoint 2007. Right now I need some advice on my disk layout. I have two Dell servers that are configured a little differently in terms of storage. The principle server will be using a combination of local storage and san storage. I have to work with what I have the organization is currently all allocated on san storage it was like pulling teeth to even get what I have to work with now. My disk setup on the principle is as follows: raid 1 for OS raid 10 for logs raid 10 fiber on san for high IO databases raid 10 sata on san for content databases My question in regards to the principle server is where should I place the temp db? I thought about placing it on the fiber raid 10 which will be hosting my high IO Sharepoint SSP databases my only other choice is to move it to the raid 1 os partition which I’m sure you guys will be against. Now let’s talk about the mirror server it is not connected to the san it is all local 6 15k SAS drives. Now my question is the same do I put tempdb on the os partition or do I leave the os partition and use a single raid 10 for everything? Any help you can provide is much appreciated.

• PostgreSQL failover cluster on Windows Server

  - by user36997

  We are looking for advice on how to setup a basic failover cluster for our application: We will be using 4 machines running Microsoft Windows Server (most probably 2003). All four will always run our application, which is essentially a web service. Load balancing is "outsourced" - somebody else handles the distribution of the web requests among the servers. Only one of the servers will be running the PostgreSQL server actively at any given time. Another server (of the four) also has the DB installed, but is on standby/passive. The DB data is stored on shared storage. No copying data between servers. Reads are done very frequently by many end-users, and in rather small chunks of data. Writes are done much less frequently, by less users, and in very large bulks of data. Now, how can one configure Microsoft Cluster Service to keep only one instance of the DB server and 4 instances (1 per server) of our application at all times? And does PostgreSQL integrate neatly with MSCS at all? Update: Instead of keeping the data on shared storage, I also consider using log shipping to replicate data on a couple of DB servers. There are two issues with this option: Log shipping only makes sure that I have a second server that gets all of the data and is ready to take over. How do I implement the actual failure detection and failover switch? Switching back: Suppose the master fails and the system automatically fails over to the slave, and later the master comes back online. I understand that with WAL shipping this will require to reconfigure the log shipping once again, and that switching back is far from seamless. Is that so?

• Free web-based software for team collaboration/documentation

  - by Jason Antman

  Looking for some advice here, as my search has turned up to be pretty fruitless. My group (9 people - SAs, programmers, and two network guys) is looking for some sort of web tool to... ahem... "facilitate increased collaboration" (we didn't use a buzzword generator, I swear). At the moment, we have an unified ticketing system that's braindead, but is here to stay for political/logistical reasons. We've got 2 wikis ("old" and "new"), neither of which fulfill our needs, and are therefore not used very often. We're looking for a free (as in both cost and open source) web-based tool. Management side: Wants to be able to track project status, who's doing what, whether deadlines are being met, etc. Doesn't want full-fledged "project management" app, just something where we can update "yeah this was done" or "waiting for Bob to configure the widgets". TeamBox (www.teambox.com) was suggested, but it seems almost too gimmicky, and doesn't meet any of the other requirements: Non-management side: - flexible, powerful wiki for all documentation (i.e. includes good tables, easy markup, syntax highlighting, etc.) - good full text search of everything (i.e. type in a hostname and get every instance anyone ever uttered that name) - task lists or ToDo lists, hopefully about to be grouped into a number of "projects" - file uploads - RSS or Atom feeds, email alerts of updates We're open to doing some customizations (adding some features, notification/feeds, searching, SVN integration, etc.) but need something F/OSS that will run under Apache. My conundrum is that most of the choices I've found so far fall into one of these categories: project management/task tracking with poor wiki/documentation/knowledge base support wiki with no task tracking support ticketing system with everything else bolted on (we already have one that we're stuck with) code-centric application (we do little "development", mostly SA work) Any suggestions? Or, lacking that, any comments on which software would be easiest to add the lacking features to (hopefully ending up with something that actually looks good and works well)?

• Using IIS7 as a reverse proxy

  - by Jon

  My question is pretty much identical to the question listed but they did not get an answer as they ended up using Linux as the reverse proxy. http://serverfault.com/questions/55309/using-iis7-as-a-reverse-proxy I need to have IIS the main site and linux (Apache) being the proxied site(s). so I have site1.com (IIS7) site2.com (Linux Apache) they have subdomains of sub1.site1.com sub2.site1.com sub3.site2.com I want all traffic to go to site1.com and to say anything that is site2.com should be proxied to linux box on internal network, (believe ARR can do this but not sure how). I can not have it running as Apache doing the proxying as I need IIS exposed directly. any and all advice would be great. EDIT I think this might help me: <rule name="Canonical Host Name" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTP_HOST}" negate="true" pattern="^cto\.com$" /> <add input="{HTTP_HOST}" negate="true" pattern="^antoniochagoury\.com$" /> <add input="{HTTP_HOST}" negate="true" pattern="www.antoniochagoury\.com$" /> </conditions> <action type="Redirect" url="http://www.cto20.com/{R:1}" redirectType="Permanent" /> </rule> from: http://www.cto20.com/post/Tips-Tricks-3-URL-Rewriting-Rules-Everyone-Should-Use.aspx I will have a look at this when I have access to the IIS7 box. Thanks

• How to configure VirtualBox server for performance at home

  - by BluJai

  I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

• Windows 2008 R2 AWS CloudFormation Elastic beanstalk configuration

  - by Webmonger

  I'm looking for some configuration advice. I have a need for a load balanced windows environment with shared media across all instances that are hosting the app. The best explanation i can give is that there will be multiple Windows 2008 server with IIS hosting the app going through an ELB to load balance. Users must be able to upload content (images, video etc...) to the site that will be hosted. When a user uploads media it needs to be kept on a shared location so all windows IIS instances can access the files, I can't host the files on S3 because of the app architecture so they need to be in a place where all IIS server will have access. In addition I need to run an update each IIS server instance that updates a local memory cache when SQL data is updated. I was thinking of a configuration like this: [ELB] - [Win 2008 IIS (multiple servers)] - [Win 2008 File & SQL Server(possibly RDS?)] Does this configuration make sense? If not could you provide an idea of how I should configure it. Thanks in advance

• Exchange 2003: Unrestrict send mail size for specific users / groups?

  - by Kip

  Good (insert appropriate time of day here) SF folks, I have the following situation; We have a message size limit for sending set at 20mb in Global Settings | Message Delivery. We have a limit of 50mb set at an external 3rd party spam vendor. I need to enable some users to be able to send messages that are upwards of around 40mb in size. However, when I set the Sending Message Size Maximum to 50mb within the delivery restrictions of a users exchange properties, it would appear that this does not win. It seems that the lowest value wins for this situation. I need to be able to allow certain users to send messages larger than the 20mb limit, but to have everyone else have the 20mb limit in place. How can I do this? The only way I could see was to raise the limit set in Global Settings | Message Delivery to 50mb and then set everyone elses (bar the people who need increased limit) delivery restrictions max size down. But I cannot see an easy way to do the last bit hence my post here looking for advice. There are valid reasons we need to send mail this size and whilst we are putting together other mechanisms for delivery this data, we still need to get this put in place. Thanks in advance Kip

• Recovering Data from a Linkstation LS-WXL/R1

  - by kingkool68

  I've been running a Buffalo Linkstation LS-WXL/R1 in RAID1 for a few weeks. Two nights ago we had a brief power outage. Yesterday when I tried to mount the disk it couldn't be found. I logged in to the web admin and it couldn't see any storage attached and no arrays available. Well this sucks. I ended up taking the disks out and mounting them to an Ubuntu virtual machine. They how up as an Array but I can't start the Array to the best of my limited knowledge. I could still see the 6 partitions, so I'm confident the data is there. I can use Photorec (http://www.cgsecurity.org/wiki/PhotoRec) to recover most of the files I want, it just takes some time. Could I make an image of the data partition and mount that in Ubuntu so I can get at the data I want through the file system? 95% of the data on my Linkstation LS-WXL/R1 is backup. I just put a few folders of images on there that I need to get back. I'm already preparing to format the disks when I'm done and re-building the RAID1 array from scratch. Any advice would be appreciated.

• Mac Mini drive problems but SMART verified: bad hard drive or controller?

  - by Zac Thompson

  I have a 3-year-old Intel Mac Mini at home. About a month ago, it stopped booting from the hard drive (internal, SATA, 80GB). I tried booting from the Install Disc to repair the filesystem but Disk Utility was unable to do so ("invalid node structure"). I was also unable to use the hard drive in the Terminal from the Install Disc nor from an Ubuntu boot CD ("DRDY err"). I could see the contents of some directories, but others would give an error and I would get failures when trying to copy files. At this point I was sure the filesystem was hosed and I'd want to reformat at least. DiskWarrior was able to let me retrieve the data files I was interested in, which are now copied to an external hard drive, but it reported a high number of problems ("speed reduced by disk malfunction" count was over 2000) when in the process of trying to rebuild the directory for the drive. It also would not let me use the rebuilt directory to replace the one on the drive; it claimed the disk errors prevented recovery in this way. Under normal circumstances I would now assume that the drive itself was going bad: DiskWarrior's "disk malfunction" error above is supposed to imply hardware problems. My initial plan was to buy a replacement for the internal 2.5" drive. However: Disk Utility, command-line tools and DiskWarrior had reported all along that the SMART status of the drive was okay/Verified. So I'm now worried that the drive hardware is actually fine, and that the problems were due to a disk controller that has gone "bad" somehow. If this is the case, I'll probably just replace the whole computer. Any advice on how I can tell what is to blame? I don't have a lot of extra hardware sitting around, so I don't have the option of simply dropping the drive in another machine or popping another hard drive inside the Mini.

• Current wisdom on SQL Server and Hyperthreading?

  - by BradC

  Lots of articles out there (see Slava Oks's original SQL 2000 article and Kevin Kline's SQL 2005 update) recommend disabling hyperthreading on SQL servers, or at least testing your specific workload before enabling it on your servers. This issue is gradually becoming less relevant as true multi-core processors replace hyperthreaded ones, but what's the current wisdom on this issue? Does this advice change any with SQL 2005 64-bit, or SQL 2008, or Windows Server 2008? Ideally, this should be tested in advance in a staging environment, but what about for servers that have already made it into production with HT enabled? How can I tell if performance issues we're experiencing might be related to HT? Is there some specific combination of perfmon counters that might point me in that direction, as opposed to all the other things I normally pursue when working on improving SQL performance? Edit: This is especially attractive because of the potential for an across the board improvement for some of my high-cpu servers, but the client is going to want to see something concrete that helps me identify which servers really could benefit from disabling hyperthreading. Of course, conventional performance troubleshooting is ongoing, but sometimes any little bit helps.

• How to configure SCSI hard drives and RAID for Poweredge 2850 web server

  - by Saul

  I'm trying to set up a Poweredge 2850 as a web server, but as a server novice it's causing me some confusion. Its a virgin install so no data to be lost as yet, so I'd like to get the best arrangement for setting up Windows Server 2008. The box will run IIS, a mail and FTP server. The current physical arrangement of the hot swap drives is 1 73GB 3 146GB 5 blank 0 73GB 2 146GB 4 146GB (but flashes green, amber off) When I enter the PERC config screens on boot up I've got Raid Ch- 0 ID 0 ONLIN A00-00 1 ONLIN A00-01 2 ONLIN A01-00 3 ONLIN A01-01 4 HOTSP I think that drives 0 and 1 are set to RAID 1 and drives 2 and 3 are also set to RAID 1, certainly I can see 2 logical drives, both raid 1 of 69880MB and 139900MB Now what I think I am getting here is that the 2 73GB drives mirror each other and the 2 146GB drives mirror 2? so by my noob thinking if a drive fails I can pull it, insert and new one and it will reduplicate from its matching pair? I think the flashing amber probably indicates a failing drive in slot 4, should that just be binned? What confuses me coming from a home user XP background is that when I load up Windows Server 2008 OS under my computer I only see a C drive of about 70GB capacity. i.e wheres the 146GB drive? Any advice appreciated

• VMWare Newbie - looking for hardware recommendations and help :) [closed]

  - by Dan

  I am looking for some hardware recommendations on an upcoming virtualization project. We are a small company (80 users - 25 in site 1, 55 in site 2) currently using Windows Server 2003 - no VM servers yet. Our AD is setup where site 1 is the root domain and site 2 is a subdomain/subnet - connected by T1 and VPN for failover. The current DC's also server as file servers, print servers, AntiVirus servers. Email is in the cloud. Additionally then in site 1 we have 3 additional member servers - one running IBM Websphere for a customer specific app, one running Infor PowerLink (no real heavy load) and another that we use for Virtual Studio apps and also runs DirSync for Exchange Online. No heavy workloads on any of these machines really. We also have an AS400 box that we run ERP/CRM software on that site 2 connects to over the WAN link. In site 2 we also have a SQL machine that runs on Win2K server. Database files are not large less than 5 GB. Light to Medium workload on this machine. File servers in each site store less than 500 GB data and probably won't grow to more than 1TB in the next 5 years. I am looking to go to VMWare in both sites and virtualize all servers. What recommendations do you have for server, storage hardware? Is it safe to virtualize all of your DC's? Any help or advice would be greatly appreciated. Thanks.

• How to configure VirtualBox server for performance at home

  - by BluJai

  I currently have two physical Ubuntu Server 10.10 servers at home: one serves as our firewall/router/DHCP/VPN server and the other performs double-duty as a file server and a VirtualBox host for an Ubuntu Desktop 10.10 machine which I use from remote connections (via NoMachine) for many thin-client purposes which are irrelevant to my question. What I'd like to accomplish is to consolidate the two physical machines into one which is a dedicated VirtualBox host (most likely running Ubuntu Server 10.10). Note that I'd like to stick with VirtualBox (if possible) because I'm most comfortable with it and use it on a daily basis at both home and work. Specifically, I plan to have one VM set up as file server, another as the firewall/router/DHCP/VPN (or possibly split those a bit) and a third, which is the only current VM (already VirtualBox), which is the thin-client host. My question comes down to performance and/or recommendations about the file server VM. The file server hosts about 6 terabytes of data across 4 drives. What I'd like to do is use raw disk access from the VM directly to the existing disks. However, I'm curious what performance advantage/disadvantage that would have as compared to using shared folders from the VM host and basically just have the whole drive served as a shared folder to the VM which would then serve it to the other machines on the network. I don't know if virtual disks would even work in this scenario and I certainly wouldn't want a drive to be filled with just a single file which is 1.5 TB (disk image). To add understanding of context, but not to get additional advice, I want to virtualize these machines because I intend to regularly use the snapshot capabilities of VirtualBox for the system disks (which will be virtual drives) of the VMs and I have some physical space/power needs to address (as I mentioned, this is at home).

• DMG image containing Mac OS X 10.6.5 update not recognized

  - by Lawliet

  Hello, I want to update my Mac OS X 10.6.3 and want to use the manual package update (not Software Update) and I am having this problem for two days now. First I downloaded Mac OS X 10.6.5 Combo update and on the first opening it popped up a message saying "Unable to mount: disk image not recognized". I thought that somehow the image became corrupt during the download, so I downloaded it again. Same result. And I downloaded again. And again... No use, it still states that the .dmg is not recognized. Then I tried to update my system from 10.6.3 to 10.6.4 using the same method (package installer). It worked. And of course I downloaded the 10.6.5 update (not the combo package, but the 10.6.4 10.6.5 update package)... guess what. Not recognized. I don't understand how is this possible. Did anyone has the same problem? Please don't advice me to use software update, as I need to do that on multiple Macs Thanks in advance.

• Debian apache2 restart fault after some updates

  - by Ripeed

  can anyone give me an advice with this please: I run update on my debian server by Webmin. After updating some apache2 and etc. It shows update fail. After that I cant start apache2. I must run netstat -ltnp | grep ':80' Then kill pid kill -9 1047 and now i can start apache2 When I started it first time after update some websites on fastCGI wont work I must change them in ISPconfig3 to mod-PHP and now works NOW - I cant restart apache without kill pid. In log of ISP I see Unable to open logs (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down In log of some website I see [emerg] (13)Permission denied: mod_fcgid: can´t lock process table in pid 19264 Do you thing it will be solution update everithing by: apt-get update and apt-get upgrade to complete all updates? I have little scare if I do that then next errors will occur. If I look at apache log i see error: Debian Python version mismatch, expected '2.6.5+', found '2.6.6' But that was there before that problem before. Thanks A LOT for help.
