  • ESXi 4.1 host not recognising existing VMFS datastore

    - by ThatGraemeGuy
    Existing setup: host1 and host2, ESX 4.0, 2 HBAs each. lun1 and lun2, 2 LUNs belonging to the same RAID set (my terminology might be sketchy here). This has been working just fine all along. I added host3, ESXi 4.1, 2 HBAs. If I view Configuration / Storage Adapters, I can see that both HBAs see both LUNs, but if I view Configuration / Storage, I only see 1 datastore. host1/2 can see both LUNs and I have VMs running on both too. I have rescanned, refreshed and even rebooted, but host3 refuses to acknowledge 1 of the datastores. Does anyone know what's going on? Update: I re-installed the host with ESX (not i) 4.0, same version as the existing hosts and it's still not recognising the vmfs. I think I'm going to SVmotion everything off that datastore then format it. Update2: I've created the LUN from scratch and the problem gets even weirder. I've presented the LUN to all 3 hosts, and I can see the LUN in the vSphere client's Configuration / Storage Adapters section on all 3 hosts. If I create a datastore on the LUN via the Configuration / Storage section on host1, it works fine and I can create an empty folder via datastore browser, but the datastore is not seen by the host2 and host3. I can use the Add Storage wizard on host2 and it will see the LUN. At this point the "VMFS Label" column has the label I gave with "(head)" appended. If I try the Add Storage wizard's "Keep the existing signature" option, it fails with an error "Cannot change the host configuration." and a dialog box that says 'Call "HostStorageSystem.ResolveMultipleUnresolvedVmfsVolumes" for object "storageSystem-17" on vCenter Server "vcenter.company.local" failed.' If I try the Add Storage wizard's "Assign a new signature" option on host2, it will complete and the VMFS label will have "snap-(hexnumber)-" prepended. At this point its also visible on host3, but not host1. I have a similar setup in a different datacenter which didn't give me all this trouble.

  • What is the difference between the Linux and Linux LVM partition type?

    - by ujjain
    Fdisk shows multiple partition types. What is the difference between choosing 83) Linux and 8e) Linux LVM? Choosing 83) Linux also works fine for using LVM, even creating a physical volume on /dev/sdb without a partition table works. Does picking a partition type in fdisk really matter? What is the difference in picking Linux or Linux LVM as partition type? [root@tst-01 ~]# fdisk /dev/sdb WARNING: DOS-compatible mode is deprecated.

  • Looking to replace Ghost with FSArchiver or Clonezilla, few questions about capabilities

    - by Daniel Wright
    I work for a PC Repair company and we are looking into setting up a dedicated machine with externally accessible SATA bays to clone harddrives as a safety net incase something goes wrong during a repair. We currently use a SATA/PATA to USB bridge called MagicBridge and Norton Ghost on any workstation, but we're looking to move away from Ghost. We have a computer with a large RAID5 array with Windows Server 2008 Standard currently installed, but this can be replaced with a flavour of *nix. I have some experience with Clonezilla, but FSArchiver also seems like a suitable replacment too. My Head Technician wants to know if my chosen solution (probably Clonezilla or FSArchiver, but I'm open to free suggestions) is capable of: Cloning a degraded RAID, such as a single drive from a RAID1 mirror without complaining Producing images that are easily mountable (he'd prefer them to be mountable in Windows, but if there is no other easy way, *nix should be fine) akin to Ghost Explorer so individual files can be restored as well as being able to do bare metal restores. My apologies for wordiness but I wanted to be thorough in my explaination. Thanks for any suggestions or tips :) EDIT: I've just found out that Clonezilla has a workaround for cloning RADI1 drives EDIT2: Found the answer to both of my questions, aparently I wasn't phrasing my searches right, could this question be deleted please?

  • CentOS Installation on a Cisco MCS 7800

    - by William
    I'm having some problems installing CentOS 5.5 Final (i386) onto my server, a Cisco MCS 7800. The problem comes very early into the installation. When the welcome screen comes up and gives you the option on how to boot into the DVD, I'll press enter to go into the graphical installer. The screen will then have a blinking cursor in the top left of the screen and will never go away (I thought that it just might need time but I let it sit for over 5 hours). I then booted into it again and tried using Linux Text thinking it was a problem with the graphical installer. That didn't work, same problem. Then I tried a DVD of RHEL 5 and got the same problem, both graphical and Linux text. At this point I think it's a hardware problem. The server has 2GB of ECC RAM, 1 Pentium 4 CPU @ 3.06GHZ and 2 WD Hard Drives (80GB) configured for RAID 0. (There is also an option in the BIOS for what OS type and that is set to Linux.) If anyone has any idea what is going on, it would be helpful. Edit Typing "text" doesn't change a thing. Still stuck at the blinking cursor. I looked it up and it's really the same thing as typing "linux text", which as stated in the first part of my question, I've already done.

  • On what should i not be pennywise buying a machine for SqlServer 2008?

    - by Michel
    Hi, i'm going to do a project for a client and i'll be hosting the database server myself. Normally it would be on my dev machine, but there will also be data pushed into it during developing and testing, so i would like to setup a dedicated test sql server. But, as you might guess, i can't afford to go to Dell and buy one mega 16 core 16 GIG 10 TB raid 5 machine (wow, that sounds cool) So i have to save the money somewhere... the hardware only has to live for a year (longer is nice of course), and the sql server won't be hit too hard: i guess the average server will only see it as a cough once in a while. But i do want the machine to be a bit performant: if it does get some data, it must be a bit responsive. So my question is were can i leave out the expensive parts: is 2 GB enough, or must i take 4GB, is an average processor enough or should it be a top of the bill? Is Sql server a large resource user or is a simple desktop pc good enough? It wil run on win2008 by the way.

  • Virtual machines with failover setup

    - by kimmmo
    We have three servers and our plan is to run a number of virtual machines on them in such manner, that if one of the nodes blow up, we can either quickly or seamlessly get a spare running on another node. In addition to the normal networking, they're interconnected via dual 10Gbit NIC's, so networked raid/mirroring shouldn't be a problem. The guest VM's are mostly going to be running text mode linux, but of course it wouldn't hurt to be able to spin up a non-mission critical windows guest for running Visual Studio or checking IE compatibility of a web app. We've spent some time trying to get some magical cloud setup running using Stackops and Crowbar but it started to look like they were offering way too much and were too complicated for our needs. The next candidate, I think, is Ubuntu 11.04 server + KVM + Ganeti + Drbd, unless you can come up with a suggestion for a better solution that we have missed. Requirements: Installation should be simple or at least understandable without being in the dev team A browser interface for creating and managing VM's is a nice bonus Single node's hardware failure should cause minimal downtime for VM's that were running on that node Adding more nodes should be possible without shutting down the VM's.

  • MySQL Config on Large Machine

    - by Jonathon
    We have a Windows 2003 Enterprise Edition server (64bit) running only MySQL 5.1.45 64-bit. It has 16G RAM and 10T of hard-drive space in RAID 10. We are having horrible performance from mysqld (85-100% CPU utilization). We were running a smaller machine with better performance, so I am assuming our my.ini file is not correct for our current machine. The my.ini file is as follows: [client] port=3306 [mysql] default-character-set=latin1 [mysqld] port=3306 basedir="D:/MySQL/" datadir="D:/MySQL/data" default-character-set=latin1 default-storage-engine=MYISAM sql-mode="" skip-innodb skip-locking max_allowed_packet = 1M max_connections=800 myisam_max_sort_file_size=5G myisam_sort_buffer_size=500M table_open_cache = 512 table_cache=8000 tmp_table_size=30M query_cache_size=50M thread_cache_size=128 key_buffer_size=3072M read_buffer_size=2M read_rnd_buffer_size=16M sort_buffer_size=2M #replication settings (this is the master) log-bin=log server-id = 1 Does anyone see anything wrong with this setup? For a machine with this much RAM, why in the world would mysqld eat up so much CPU? I know we can optimize some queries, etc., but it did run okay on a smaller machine, so I am pretty sure it is the config. Thanks in advance for any help.

  • Is UPS worthwhile for home equipment?

    - by Jon Skeet
    Over the years, I've had to throw away a quite a few bits of computing equipment (and the like): Several ADSL routers with odd symptoms (losing wireless connections, losing wired connections, DHCP failures, DNS symptoms etc) Two PVRs spontaneously rebooting and corrupting themselves (despite the best efforts of the community to diagnose and help) One external hard disk still claiming to function, but corrupting data One hard disk as part of a NAS raid array "going bad" (as far as the NAS was concerned) (This is in addition to various laptops and printers dying in ways unrelated to this question.) Obviously it'll be impossible to tell for sure from such a small amount of information, but might these be related to power issues? I don't currently have a UPS for any of this equipment. Everything on surge-protected gang sockets, but there's nothing to smooth a power cut. Is home UPS really viable and useful? I know there are some reasonably cheap UPSes on the market, but I don't know how useful they really are. I'm not interested in keeping my home network actually running during a power cut, but I'd like it to power down a bit more gracefully if the current situation is putting my hardware in jeopardy.

  • Why my internal hard disk can be ejected?

    - by Bear Bear
    I have 6 hard disks in my computer and one DVD. The disk that I connect to the 6th SATA port is a regular disk. But my Windows 7 64 bit shows it as a removable drive. I can eject my hard disk! Just like a pen drive. If I connect another disk to the 6th port, I can eject that disk too. So it has nothing to do with the physical disk, it must be something related to Windows or BIOS I don't understand why Windows 7 is seeing a normal hard disk as removable. In Computer Management - Disk Management, the disk looks identical to the others - there is nothing there to suggest the drive is different from the others. But in the tray I have the icon to eject it. The motherboard model is ASUS F2A85 V PRO FM2. All the disks are formatted normally, no Dynamic Disk, no RAID, nothing special. How can I tell Windows 7 to treat the disk exactly like the others, so it can't be ejected?

  • Splitting build cross the network?

    - by Dandikas
    Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software?

  • Provisioning DELL servers using only linux tools

    - by Krist van Besien
    We have taken delivery of a bunch off Dell Poweredge Rack servers. Unfortunately when ordering it was neglegted to ask for dhcp to be enabled in the built in iDRAC controlers... So they are all stuck on the same IP address. Which means that I'll have to go to each of them individually and configure a new IP in the console... In the future I want to avoid that. Now Dell proposes to deliver the next batch with auto discovery enabled. As I understand this means that when the machine wakes up for the first time the iDRAC will request a DHCP address. The DHCP server then supposedly also provides a "provisioning" server, that provides it with a username and password, and a configuration to be applied. This would allow us to for example configure things like RAID automatically. However, I can't seem to find a way to set up such a provisioning server that does not involve setting up a windows machine. I want to use Linux tools exclusively. Is there a way to do this? I want to just rack servers, switch them on, and then do everything remotely. And that using only linux tools?

  • How to best tune my SAN/Initiators for best performance?

  • Disk wipe preferences

    - by hmvm123
    I manage a pool of systems that are loaded with software and sent to potential customers for evaluations which often land sensitive information on the drives. Before shipping them back, they typically like a standard wipe to be run to clean out the drives. Most are familiar with DBAN so I try to make sure it can work on my systems. Unfortunately, this means I'm usually in RAID driver hell trying to make sure that the versions out there support the ones my systems are shipping with. These are various kinds of 3ware and LSI ones. Consequently, I have DBAN 1.0.7 working on some, a beta version of 2.0 on the others and 2.2.6 on some of the latest SSD based ones. Now with the LSI controllers on my IBM x3550 M3s (1064/1068) I'm getting no love at all. Is there a way out? Do you buildroot with DBAN and try to piece the drivers together? Any other tools, free or commerical, that stay updated. I'm trying to walk people of varying technical proficiencies through this, so a boot disk with simple choices is preferable.

  • bootmgr image is corrupt

    - by bacord
    I just replaced my HD with a SSD. I did a brand new install on the SSD and I received the following error after booting BOOTMGR image is corrupt. The system cannot boot. A little configuration for your knowledge. The system used to be a dual boot with XP & windows 7. After replacing the original startup HD with my SSD I changed a setting in the bios to AHCI (I have tested changing it back but this did not help).

  • Network access lags for Win7 when server network utilization is high

    - by Jeff Miles
    We have a Dell PE2950 file server running Windows 2008, hosting a DFS namespace of ~1.2 TB. This server has two Broadcom 1Gbps NICs teamed together. When there is high traffic going to the server across the network (greater than 200 Mbps), any Windows 7 client accessing a DFS share at the time experiences severe performance problems. For example: Computer A has an AutoCAD drawing opened directly from the DFS share. Performance is normal, not causing any issues. Computer B begins a file transfer, putting a 11GB file onto a different DFS namespace, on the same server Computer A immediately notices lag while using AutoCAD. The cursor momentarily freezes within AutoCAD every 10 seconds or so, and any browsing of the DFS share is extremely slow. Computer B completes file transfer, and performance resumes to normal for Computer A. This is only affecting Windows 7 clients, using a variety of hardware (desktop + laptop). All of our Windows XP clients see no performance impact during the file transfer. Things I have tried with no change: Had Computer A work from an entirely different RAID array from the file transfer destination Updated NIC drivers on clients and server Enabled TCP offload and receive side scaling on the server NIC (previously disabled when the issue began) Antivirus disabled during file transfer I am currently having a user test applications other than AutoCAD when the file transfer occurs, and will update the question with that result. Does anyone have any recommendations for resolution or additional troubleshooting steps?

  • How to export SQL Server data from corrupted database (with disk write error)

    - by damitamit
    IT realised there was a disk write error on our production SQL Server 2005 and hence was causing the backups to fail. By the time they had realised this the nightly backup was old, so were not able to just restore the backup on another server. The database is still running and being used constantly. However DBCC CheckDB fails. Also the SQL Server backup task fails, Copy Database fails, Export Data Wizard fails. However it seems all the data can be read from the tables (i.e using bcp etc) Another observation I have made is that the Transaction Log is nearly double the size of the Database. (Does that mean all the changes arent being written to the MDF?) What would be the best plan of attack to get the database to a state where backups are working and the data is safe? Take the database offline and use the MDF/LDF to somehow create the database on another sql server? Export the data from the database using bcp. Create the database (use the Generate Scripts function on the corrupt db to create the schema on the new db) on another sql server and use bcp again to import the data. Some other option that is the right course of action in this situation? The IT manager says the data is safe as if the server fails, the data can be restored from the mdf/ldf. I'm not sure so insisted that we start exporting the data each night as a failsafe (using bcp for example). IT are also having issues on the hardware side of things as supposedly the disk error in on a virtualized disk and can't be rebuilt like a normal raid array (or something like that). Please excuse my use of incorrect terminology and incorrect assumptions on how Sql Server operates. I'm the application developer and have been called to help (as it seems IT know less about SQL Server than I do). Many Thanks, Amit

  • Win2008: Boot from mirrored dynamic disk fails!

    - by Daniel Marschall
    Hello. I am using Windows Server 2008 R2 Datacenter and I got two 1.5TB S-ATA2 hard disks installed and I want to make a soft raid. (I do know the disadvantages of softraid vs. hardraid) I have following partitions on Disk 0: (1) Microsoft Reserved 100 MB (dynamic), created during setup (2) System Partition 100 GB (dynamic) (3) Data partition, 1.2TB (dynamic) I already mirrored these contents to Disk 1. Its contents are: (1) System partition mirror, 100 GB (dynamic) (2) Data partition, 1.2 TB mirror (dynamic) (3) Unusued 100 MB (dynamic) -- is from "MSR" of Disk 0, created during setup. Since data and system partition are mirrored, I expect that my system works if disk 0 would fail. But it doesn't. If I force booting on disk 0: Works (I get the 2 bootloader screen) If I force booting on disk 1 (F8 for BBS), nothing happens. I got a blank black screen with the blinking caret. I already made disk1/partition1 active with diskpart, but it still does not boot from this drive. Please help. Both partitions are in "MBR" partition style. They look equal, except the missing "MSR" partition at the partition beginning (which seems to be not relevant to booting). Regards Daniel Marschall

  • How to organise storage for media content such as video and music?

    - by thor
    Currently, we have a single server hosting all content: music, video and software. This content is downloaded by users through HTTP. Now free space is coming to an end and we are exploring different ways of extending our storage capacity. We want to do it cheap, simple and reliable (protected from disk/ server faults). Currenly, we see two ways: Add a couple of cheap servers with 4 disks (RAID1 ?), run some distributed file-system on top, like GlusterFS. Pros: hopefully, we will see all our disks as single flat file system, just dump content into it and be done. Cons: could be tricky in configuration and handling of faults. Add a couple of cheap servers, all running HTTP servers. Each piece of content (be it a music file or video) is placed on randomly selected two servers. Pros: don't have to deal with RAID, as content is duplicated; single server failure does not bring down any part of content; doubled distribution capacity (as any signle file could be downloaded from any of two servers hosting it). Cons: requires some scripting on part of distribution of content, adding/ removing servers. Do we miss any other ways? Which of the aforementioned options seems to be the best?

  • How do I install Windows XP from an external hard drive?

    - by Plasmer
    I'm trying to install Windows XP Media Center edition by copying the install disc image to an external hard drive and making it bootable. Has anyone had success getting this to work on systems that can't boot from dvds/floppies? I'm basically working from this guide: http://www.dl4all.com/other/21495-install-windows-xp-from-usb.html Update - 2/15/10 I used WinToFlash on my laptop to format my usb hard drive from my install dvd (Windows XP Media Center Version 2005 with Update Rollup 2 from Dell) and selected "boot from usb device" at the boot selection menu and the windows installer started up. However, an error message came up saying that: "A problem has been detected and windows has been shut down to prevent damage to your computer." Originally on my desktop machine, I had 1 150Gb SATA drive, and 2 150 Gb SATA drives striped together using RAID. From the hard drive diagnostics, it appears the windows install on one of the RAIDed disks lost a block and this has been preventing me from booting up. I replaced the standalone drive with a new 1Tb SATA drive and disconnected the other hard drives. Could the message be indicating a virus is on the unformatted drive? or the usb hard drive? Update 2 - 2/15/10 The external hard drive didn't find any viruses when scanned. I tried installing Vista Home Premium 64bit SP1 using WinToFlash and that installed successfully onto the new 1Tb drive. WinToFlash was really easy to use and helped a lot, thanks!

  • VMware NAS/iSCSI recommendations - smallish organization

    - by Bubnoff
    I have two VMware servers - ESX + ESXi. Two backup NAS boxes. The current NAS boxes are low-cost and unsuitable for running VMs from. Support NFS only. Slow. My plan is to have a dedicated iSCSI/NAS for storing and running VMs. Two additional low-cost boxes for backup. I'm looking for advice regarding 2 things really: Recommendations as far as VMware architecture/design for a smaller organization. Less than 20 Virtual Machines. 2 servers + 2 x 1.5 terabyte backup NAS boxes. A good NAS/iSCSI box with your recommendation on RAID config ...I would go with 6 or better. I'm trying to design an installation that is both fast and reliable/redundant. If you have any experiences to share or your current configuration including network design ( switches, fiber ...etc ), I will be enormously thankful. I'm not married to this idea, so if you have a design not using iSCSI NAS boxes ...let er rip. Cost? Can we stay around $5,000 ( on top of already stated components )? Links to info are welcome also. Thanks for reading! Bubnoff

  • Data Store/Volume disconnecting. How to resume copy of VMDK?

    - by Serge
    I'm having an issue with my ESXi 4.1 hosts losing the datastore with FC SAN after a power outage. All 3 hosts disconnect so it's definitely a SAN issue. I've tried to resolve the issue on the SAN side with the SAN software support and Adaptec hardware support. No luck there. So I'm stuck with a SAN that will randomly disconnect the volume. I need to get the virtual machines (VMDK files) from the datastore. The problem is I can only get 5-20% before the data store disconnects. I have backups that are slightly older that I can use to replicate the VMDK differences to. What has not worked so far: Powering up the VMs, will boot up for 5-15 minutes then freeze vCenter migrate or clone of VM, will fail after similar period of time vCenter copy/paste of VMDK. Was able to get one 30GB VMDK and no luck after that. vMware Data Recovery. Fails at low %, can't resume, so next backup starts from begining. Veeam Backup & Recovery. Same as above, no resume function. If I can just find a backup solution that will resume from the failed spot that would solve my issue. Anyone have any ideas that I could try? EDIT 1 The SAN is Open-E DSS 6 running on a Supermicro 24 drive enclosure with 4 port Qlogic FC. Adaptec 52445 RAID card.

  • What is the recommended glusterFS configuration for a growing website?

    - by montana
    Hello, I have a website that is tracking towards 50 million hits per day average, and within the next 3 months should be over 100 million hits per day. We are trying to use GlusterFS v 3.0.0 (with latest patches as of 1-17-2010) Currently, we've just upgraded to a load balancer environment that has 3 physical hosts with 6 Xen-Server 5.5u1 VM's (2 on each host) to serve webpage traffic. Each machine has 6 Raid-6 local storage drives (7200RPM-SATA). The old machine we came from had 1 mirrored SAS 10k drive. We also set up glusterFS currently with 3 bricks, one on each host, and it is serving the 6 VM's as clients. In testing, everything seemed fine. However when we went to production, it seemed that there just wasn't enough I/O's available to serve traffic even upwards of 15mil hits. Weeks prior, our old server was able to handle traffic, maxed out, at 20mil. Is there any recommended configurations for such an application, or things to be aware of that isn't apparent with their documentation at gluster.org for a site our size?

  • mysqld refusing connections from localhost

    - by Dennis Rardin
    My mail server (Ubuntu 10.04) uses mysql for virtual domains, virtual users. For some reason, mysqld has started refusing connections from localhost. I see these in the mail server log: Oct 6 00:31:14 apollo postfix/trivial-rewrite[16888]: fatal: proxy:mysql:/etc/postfix/mysql-virtual_domains.cf(0,lock|fold_fix): table lookup problem and: Oct 7 13:39:15 apollo postfix/proxymap[25839]: warning: connect to mysql server 127.0.0.1: Lost connection to MySQL server at 'reading initial communication packet', system error: 0 I also get the following in auth.log: Oct 6 22:33:31 apollo mysqld[31775]: refused connect from 127.0.0.1 Telnet to the local port: root@apollo:/var/log/mysql# telnet localhost 3306 Trying ::1... Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. root@apollo:/var/log/mysql# I am not sure why this started happening, but there was a disk failure in a RAID 1 pair a bit earlier that day. So it's possible I have a damaged config file or something. But mail was working for at least an hour after the drive event, so who knows for sure? phpmyadmin works fine, and the databases themselves look like they're intact. I think/believe that selinux and iptables are disabled and not running. So ... why is mysqld refusing connections from localhost? What should I check? What processes might cause this if a .conf file or possibly a binary was damaged? Which other log files might contain clues? I've enabled "general logging" in /etc/mysql/my.cnf, but I get no interesting or informative entries there. Thanks, m00tpoint
