  • linux hardware raid 10 / lvm / virtual machine partition alignment and filesystem optimization

    - by Jason Ward
    I've been reading everything I can find about partition alignment and filesystem optimization (ext4 and xfs) but still don't know enough to be confident in setting up my current configuration. My remaining confusion comes from the LVM layer and if I should use raid parameters on the filesystem in guest os'es. My main questions are: When I use 'pvcreate --dataalignment' do I use the stripe-width as calculated for a filesystem on RAID (128kB for ext4 in my situation), the Stripe size of the RAID set (256kB), something else altogether, or do I not need this? When I create ext2/3/4 or xfs filesystems in guests on the Logical Volumes, should I add the settings for the underlying RAID (e.g. mkfs.ext4 -b 4096 -E stride=64,stripe-width=128)? Does anyone see any glaring errors in my set up below? I'm running some benchmarks now but haven't done enough to start comparing results. I have four drives in RAID 10 on a 3ware 9750-4i controller (more details on the settings below) giving me a 6.0TB device at /dev/sda. Here is my partition table: Model: LSI 9750-4i DISK (scsi) Disk /dev/sda: 5722024MiB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 1.00MiB 257MiB 256MiB ext4 BOOTPART boot 2 257MiB 4353MiB 4096MiB linux-swap(v1) 3 4353MiB 266497MiB 262144MiB ext4 4 266497MiB 4460801MiB 4194304MiB Partition 1 is to be the /boot partition for my xen host. Partition 2 is swap. Partition 3 is to be the root (/) for my xen host. Partition 4 is to be (the only) physical volume to be used by LVM (for those who are counting, I left about 1.2TB unallocated for now) For my Xen guests, I usually create a Logical Volume of the needed size and present it to the guests for them to partition as needed. I know there are other ways of handling that but this method works best for my situation. Here's the hardware of interest on my CentOS 6.3 Xen Host: 4x Seagate Barracuda 3TB ST3000DM001 Drives (sector size: 512 logical/4096 physical) 3ware 9750-4i w/BBU (sector size reported: 512 logical/512 physical) All four drives make up a RAID 10 array. Stripe: 256kB Write Cache enabled Read Cache: intelligent StoreSave: Balance Thanks!

  • Domain names timing out after VPS IP change

    - by Fourjays
    I rent a CentOS 5 VPS from a UK-based provider, with DirectAdmin also installed. On Thursday night, they carried out planned maintenance to changed the two IPs I had been assigned to two new ones. On Friday, after the change had taken place, I updated my domain name records to reflect the IP change. Since then, all of the domains pointing to the VPS are timing out. Additionally, DirectAdmin was also not responding, but was was resolved by running the ipswap scripts as found in the DirectAdmin knowledgebase. It did not fix my domains though. I have contacted the VPS provider but I have been waiting for a response for some time now. I have checked again, and again, and all the IPs referenced in DirectAdmin are correct. If I go to the server IP in my browser it responds with "Apache is functioning normally." Email accounts on the server are also functioning correctly. But if I access a domain itself, it times out. Running a ping and a DNS look-up, I can confirm the nameserver IPs are correct. If I run a trace route it reaches an IP that is similar to my VPS IPs (last 2 blocks are different) before timing out (it never shows my server IP). I am relatively new to VPS management so don't have a vast wealth of experience with troubleshooting problems on them. I have checked all of the httpd configuration files, which don't seem to have any IP references in them at all. Looking in the Apache error logs, what errors there are do not coincide with times I have tried to access the site. Is this issue at my provider's end? Is there anything else I can check or test, to rule out post-IP-change problems with my server configuration? It was all running fine prior to the IP change.

  • BTrFS crashhhh?

    - by bumbling fool
    I create a new BTrFS raid10 file system using two 250GB drives and the second partition on a third 80GB drive. I create a subvol and snapshot. I mount the snapshot and start copying 8GB of data to it. It gets to around 1GB and the Desktop disappears and what looks like a non interactive terminal comes up with dump/crash information. I don't have a camera handy or I'd take a picture and post it. It basically looks like stack trace info. CTRL-ALT F7 will eventually bring back the Desktop though but the entire BTrFS portion of the OS is hung and non responsive until I reboot. I've reformated and reproduced this problem 3 times now and I'm about to give up :( I realize it is possible this problem is not entirely BTrFS' fault because I'm on natty which is still alpha. More granular details in case I'm an idiot: 1) Create FS: sudo mkfs.btrfs -m raid10 -d raid10 /dev/sda2 /dev/sdb /dev/sdc 2) Initial temporary mount: mkdir /btrfs && sudo mount -t btrfs /dev/sda2 /btrfs 3) Create subvol btrfs s c /btrfs/vm 4) Create initial snapshot: (optional) btrfs s sn /btrfs/cantremember.snap.something 5)unmount /btrfs and mount /btrfs/vm sudo mount -t btrfs -o subvol=vm /dev/sda2 /btrfs/vm 6) Copy data to subvolume. 7) Balance data across drives: (optional) btrfs f bal <path> (never get to this step 7...) Am I doing something wrong?

  • Excessive PHP errors in Joomla

  • OpenVPN with MacOS X Client and same subnets in local and remote net.

    - by Daniel
    I have a homenetwork 192.168.1.0/24 with gteway 192.168.1.1 and a remote network with the same parameters. Now I want to create a OpenVPN tunnel between those networks. I have no problems with Windows, because Windows routes everything to 192.168.1.0/24 except 192.168.1.1 throught the tunnel. On MacOS X however I see the folling line in the Details window: 2010-05-10 09:13:01 WARNING: potential route subnet conflict between local LAN [192.168.1.0/255.255.255.0] and remote VPN [192.168.1.0/255.255.255.0] When I list the routes I get the following: Internet: Destination Gateway Flags Refs Use Netif Expire default 192.168.1.1 UGSc 13 3 en1 127 localhost UCS 0 0 lo0 localhost localhost UH 12 3589 lo0 169.254 link#5 UCS 0 0 en1 192.168.1 link#5 UCS 1 0 en1 192.168.1.1 0:1e:e5:f4:ec:7f UHLW 13 17 en1 1103 192.168.1.101 localhost UHS 0 0 lo0 192.168.6 192.168.6.5 UGSc 0 0 tun0 192.168.6.5 192.168.6.6 UH 1 0 tun0 My Interfaces are en1 - My local Wifi network tun0 - The tunnel interface As can be seen from the routes above there is no entry for 192.168.1.0/24 that routes the traffic through the tunnel interface. When I manually route a single IP like 192.168.1.16 over the tunnel gateway 192.168.6.6, this works. Q: How do I set up my routes in MacOS X for the same behaviour as on windows, to route everything except 192.168.1.1 through the tunnel, but leave the default gateway to be my local 192.168.1.1 ?

  • Loopback connection via PHP's getimage size crashes server (Magento's CMS)

    - by Alex
    We were able to trace down a problem that is crashing our NGINX server running Magento until the following point: Background info: Magento Backend has a CMS function with a WYSIWYG editor. This editor loads some pictures via a controller in magento (cms/directive). When we set the NGINX error_log level to info, we get the following lines (line break inserted for better readability): 2012/10/22 18:05:40 [info] 14105#0: *1 client closed prematurely connection, so upstream connection is closed too while sending request to upstream, client: XXXXXXXXX, server: test.local, request: "GET index.php/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL,,/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9024", host: "test.local" When checking the code in the debugger, the following call does never return (in ´Varien_Image_Adapter_Abstract::getMimeType()` # $this->_fileName is http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif` # $_SERVER['REQUEST_URI'] = http://test.local/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL list($this->_imageSrcWidth, $this->_imageSrcHeight, $this->_fileType, ) = getimagesize($this->_fileName); The filename requests is an URL to the same server which is requesting the script a link to a static .gif that is not existing. Sample URL: http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif When the above line executed, any subsequent request to the NGNIX server does not respond any more. After waiting for around 10 minutes, the NGINX server starts answering requests again. I tried to reproduce the error with a simple test script that only calls getimagesize() with the given URL - but this not crash. It simple leads to an exception saying that the URL could not be loaded (which is fine as the URL is wrong)

  • Diagnosing PCI issues

    - by dtsazza
    I'm upgrading a PC for a friend, and have run into a problem with upgrading the motherboard. I've been assembling custom PCs for the best part of a decade now, so I'm happy enough with the basics at the very least. The motherboard, CPU and graphics card were all updated at once - after this was done, the machine POSTs but the PCI wireless card, as well as the PCI-E graphics card, do not seem to be recognised at all by the system. No trace of them anywhere in the BIOS, or the POST output, or in Windows. I booted into Linux and ran an lspci which also showed up no sign of them. What is the best step to go about diagnosing this? Is it likely/feasible that the motherboard's PCI bus is just defective and it needs to be RMAed? Are there any other common gotchas that might cause these symptoms? For reference, the components in question are: CPU: Celeron E1400 Motherboard: Gigabyte GA-G31M-ES2L Graphics card: TBC (a low end card from a couple of years ago; worked flawlessly before the mobo change) PCI WNIC: Edimax 7128G Thanks in advance for any help.

  • Cannot install CentOS 6.5 using UEFI usb boot

    - by Vaindil
    I am trying to dual-boot CentOS 6.5 on my desktop that is currently running Windows 8.1. I have two storage devices: an SSD that has my Windows installation, and an HDD that has all of my data. Both are formatted using GPT, and Windows boots using UEFI. I used the CentOS 6.5 live DVD (CentOS-6.5-x86_64-LiveDVD.iso) to create an EFI-bootable flash drive (it does boot properly in EFI mode). I receive an error, however, when CentOS is booting (error is below). I have a 6.4 boot DVD which boots as expected, but it does not boot in UEFI mode and therefore doesn't play nicely with my Windows installation (I have no way to access it, even using rEFInd or any other similar tools). What do I need to do to get the device to boot properly in UEFI mode? Kernel panic - not syncing: Attempted to kill init!

  • Fail2Ban adds iptable rules but they are not working?

    Fail2Ban just blocked my IP for 3 SSH attempts. It added the iptables rule and I can see it using the "sudo iptables -L -n" command. But I can still access the site and login through SSH!

  • How would I force Debian to use the physical sector size on a hard disk?

    - by Confused User
    I just purchased a few new 3TB WD drives. These have physical 4k sectors, but there is some sort of layer which is providing 512B logical sectors (see the partition table below). In order to attempt to get some more speed out of my hard drives, I would like to get rid of this logical layer and actually use the physical 4k sectors. However, I can't figure out how to do this (or even if it's possible) from the man pages of fdisk and parted, or from searching Google. Does anybody know how this could be done? As to why this is relevant, this page demonstrates that meerly aligning the sectors properly can already make up to a 25% speed difference for reads, and more than 2500% for writes in some cases! Getting rid of the logical sectors in favor of the physicals ones should improve speeds even more. Thanks! $ parted /dev/sdc GNU Parted 2.3 Using /dev/sdc Welcome to GNU Parted!

  • Using public interfaces on a server connected through a GRE tunnel

    - by Evan
    I'm pretty new to networking so please forgive any terminology mistakes. I have 2 servers connected with a GRE tunnel. Server1 (10.0.0.1) ---- Server2 (10.0.0.2) I want to be able to bind to the public IPs on Server2 using Server1. To do this, I setup virtual interfaces with Server2's public IPs on Server1 and then used routing rules on Server1 to route the packets through the GRE tunnel. On Server1: ip rule add from [Server2's first public IP] table gre ip rule add from [Server2's second public IP] table gre ip route add default via 10.0.0.2 dev gre1 table gre This works great and I can see the packets arriving via GRE on Server2. I can see the packet exiting the tunnel on Server2's gre1 device as shown: From Server1: ping -I [Server2's public ip] google.com tcpdump from Server2's GRE tunnel device: 12:07:17.029160 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84) [Server2's public ip] > 74.125.225.38: ICMP echo request, id 6378, seq 50, length 64 This is exactly the packet I want. However, I'm not seeing it go out at all on eth0:0 (where Server2's public IP is bound to). I've tried to use routing rules to get packets coming from Server2's public IP (which would be coming out of dev gre1) to go through dev eth0 on the public default gateway and that doesn't work either. I'm at a loss, thank you to anyone who can help.

  • how would it be possible to discover a cable modem's MAC remotely?

    - by amateurenthusiast
    i was reading the back archives of a canadian privacy law blog, and he linked to a judicial decision. apparently as part of an investigation in which were used yahoo chat and google's old 'hello' image trading program the officer was able to determine a suspect's modem's MAC address: In order to determine who STEPHTOSH was, the officer did a trace on a programme called WHO IS in an effort to learn from where STEPHTOSH was coming. WHO IS is a command program available to the public. The officer was able to ascertain that the person using the name STEPHTOSH was a Rogers Internet customer. The officer was able to obtain the Internet Protocol address, also known as the I.P. There is only one location for an I.P., which is unique to that subscriber. By use of the website known as DNS STUFF.com, one is able to find with which company this I.P. is registered. It was ascertained that the I.P. address used by STEPHTOSH was registered to Rogers Cable, from the Toronto area. The officer also learned the Cable Modem MAC address used by STEPHTOSH. This was all the information the officer was able to amass. now it was my understanding that the MAC address of any given device can only be accessed if you're only one 'hop' away on the Internet. the suspect in question was in Markham and the officer part of the Toronto Police, so it's conceivable that they both might have used Rogers internet. but would that still put them only one 'hop' away from each other? i thought the first hop after the modem was usually the ISP? and if he'd used a netBIOS query against this guy's machine it would return the ethernet card's MAC, not the modem's. so is this guy on the same rogers subnet as the suspect's cable modem, is that functionality part of google's Hello (i could only think that it would be possible if Hello operated as a virtual LAN or something), does the officer have remote access to the arp caches of the routers at Rogers or is he just full of crap and lying to make his case stronger?

  • Can I use CNAME with ip address? Why If works (sometimes)?

    - by Maciek Sawicki
    I believe that the easiest answer for the first question is "No, You have "A" for this", but I accidentally setup some subdomain using CNAME pointing to ip address and it worked on few computers in my office. I wonder how it was possible? Now, when I'm checking it from home I have following error: beast:~ viroos$ host somesubdomain.somedomain.com Host somesubdomain.somedomain.com not found: 3(NXDOMAIN) I'm 100% it used to work at my office (currently it looks like it doesn't, but I'm checking it on different machine). Therefore I'm not 100% if it worked due to some special network setup or because I tested it just after adding DNS entry. I know this story sounds, a little crazy/incredibly, but can someone help me solve this puzzle. //edit: I'm adding dig output ; <<>> DiG 9.6-ESV-R4-P3 <<>> somesubdomain.somedomain.com ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 60224 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;somesubdomain.somedomain.com.

    trying to transfer files to the work ipad via my debian7 box. When i plug it on the computer usb port, it shows the dialog about trusting this computer, and the computer shows a gnome alert about the ipad being locked and that i should unlock it and try again. i press "trust" on the ipad and try again on gnome. and it starts again. over and over. endlessly. there are dozen threads about this on apple support forums. no solution. just dozens of "me too" flags. e.g. https://discussions.apple.com/message/23082859#23082859 (44 me-too, 2k views) here is the log/messages i get Oct 23 21:17:39 dotmatrix kernel: [ 1928.517766] usb 2-1.7: USB disconnect, device number 16 Oct 23 21:17:39 dotmatrix kernel: [ 1928.715441] usb 2-1.7: new high-speed USB device number 17 using ehci_hcd Oct 23 21:17:40 dotmatrix kernel: [ 1928.811031] usb 2-1.7: New USB device found, idVendor=05ac, idProduct=12ab Oct 23 21:17:40 dotmatrix kernel: [ 1928.811036] usb 2-1.7: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Oct 23 21:17:40 dotmatrix kernel: [ 1928.811039] usb 2-1.7: Product: iPad Oct 23 21:17:40 dotmatrix kernel: [ 1928.811041] usb 2-1.7: Manufacturer: Apple Inc.

  • Windows 8 Doesn't Shutdown Properly With Fast Start-Up Enabled

    - by Patrick
    While Fast start-up is enabled, on turning the computer off (shutdown) the computer idles for about 5min after logging out/screen turning off. It then turns off. On returning into Windows I receive the error message saying Windows didn't shut down properly. Hibernate works fine, and I am told this shouldn't be the case - If one doesn't work, neither should. It works when both Fast start-up is enabled and disabled, as does restart and sleep. Windows is installed under UEFI. The UEFI ultra fast boot option for my motherboard cannot be enabled as my GPU doesn't support some UEFI GOP tech. As far as I know, not related to windows fast start-up, but thought it was worth mentioning. To clarify, if this: http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html is enabled, the computer does not shut down properly. EDIT: Some more information on the matter: Formatting didn't fix the issue. Still fails regardless of drivers installed. Hardware was purchased ~6months ago. Running a good SSD. Event viewer Always these two messages in close succession: Error (event ID 6008): The previous system shutdown at 7:45:21 PM on ?27/?10/?2012 was unexpected. Critical (kernel power, event ID 41): The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Upon installing WPT as suggested below to figure out what was happening during shutdown, and running the cmd xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP Windows fast start-up is now working consistently. Still works upon uninstalling WPT. This is the only change to occur on the computer. Nothing else has bee installed/uninstalled, no Windows Updates, nothing. Windows fast start-up did not work prior to installing WPT and running the cmd (made sure I tested).

  • finding the best network latency between two countries

    - by Yoav Aner
    I know there are many tools to test for bandwidth and latency, but they all rely on having at least one host from which you can run those tests. I wonder whether there's an online source or some other way to guestimate the latency or speed between two countries (in general). For example, would a customer in Japan get lower latency if the server is located in Singapore or Australia? Is a user in India likely to get higher download speed from a server in the UK or in the US? Are there any online resources or some clever ways to answer those questions with a reasonable degree of accuracy? [UPDATE]: Thanks for the great suggestions from Raffael Luthiger. I didn't know about those looking glass servers. The submarine cable maps were also really cool to discover (Thanks to Jesper Mortensen). Also seems really wise if I could ask those network professional in the area for their experience, but obviously I don't have access to those. At least some of them are on SF :) However, I'm still a little unsure how to combine those resources to give me some measurements. This is the information I have: Two countries (A,B). I do have IP addresses of customers in country A (I can obtain those from the web server log files for example). Presumably I can find some looking glass servers in country B and run a trace to those IPs. What's the best measurements to use? Are there any scripts that help automate at least some of this process?

  • How to configure IIS for SVG and web testing with Visual Studio?

    - by macias
    Let's say I have a simple web page with svg image in it: <img src="foobar.svg" alt="not working" /> If I make this page as static html page and view it directly svg is displayed. If I type the address of this svg -- it is displayed. But when I make this as .aspx page and launch it dynamically from Visual Studio I get alt text. If I type the address of this svg (from localhost, not as a local file) -- browser tries to download it instead of displaying. I already defined mime type in IIS (for entire server -- "image/svg+xml") and restarted IIS. Same effect as before. Question: what should I do more? Update WireShark won't work (it is in documentation), I tried also RawCap, but it cannot trace my connection (odd), luckily Fiddler worked: From client: GET http://127.0.0.1:1731/svg/document_edit.svg HTTP/1.1 Host: 127.0.0.1:1731 User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:10.0.1) Gecko/20100101 Firefox/10.0.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Answer from server: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Thu, 16 Feb 2012 11:14:38 GMT X-AspNet-Version: 4.0.30319 Cache-Control: private Content-Type: application/octet-stream Content-Length: 87924 Connection: Close <?xml version="1.0" encoding="UTF-8" standalone="no"?> <!-- Created with Inkscape (http://www.inkscape.org/) --> <svg xmlns: *** FIDDLER: RawDisplay truncated at 128 characters.
