similar to: XFS on CentOS

Hello all, I have just configured a 64-bit CentOS 5.5 machine to support an XFS filesystem as specified in the subject line. The filesystem will be used to store an extremely large number of files (in the tens of millions). Due to its extremely large size, would there be any non-standard XFS build/configuration options I should consider? Thanks. Boris. -------------- next part -------------- An

I anm trying to enable XFS with no success. I followed the instructions provided in http://wiki.centos.org/Repositories/CentOSPlus I installed the new kernel. Example: 2.6.18-8.1.14.el5.centos.plus I also installed these packages as described in a post I found yum install --enablerepo=centosplus xfsprogs xfsprogs-devel lsmod shows nothing about XFS I would image there are others out there

Hello all, I have a CentOS 5.7 machine hosting a 16 TB XFS partition used to house backups. The backups are run via rsync/rsnapshot and are large in terms of the number of files: over 10 million each. Now the machine is not particularly powerful: it is 64-bit machine, dual core CPU, 3 GB RAM. So perhaps this is a factor in why I am having the following problem: once in awhile that XFS partition

Hello all, I am running VirtualBox 4.1 on CentOS 6 and I got this warning that putting your VM's into an XFS filesystem is risky. I have also heard some rumors on the net to this effect. Does anyone know in more detail what's behind those rumors? Thanks. Boris.

Hello listmates, Has anybody attempted to run an XFS in a file mounted via -o loop? The file size is about 20 TB and it resides in a larger XFS filesystem residing on a disk. That filesystem's size is about 25 TB. What sort of degradation should one expect under that sort of scenario? The reason I am asking is that I am trying to run a MooseFS chunkserver in that filesystem-in-a-file and

Hello listmates, It appears that on the second machine in a row (CentOS 5.5, 32 bit) if I am trying to place a VM into a file located in XFS the machine just hangs (the host machine, not the VM). If I place the VM in a raw device or in a file in ext3 all seems to work perfectly. Is that just a coincidence or is there a reason for this madness? Thanks. Boris.

I noticed that my server has a lot ca. 1000x auth failure from different alocated in China / Romania and Netherlands per day since 3 days It looks to me like somebody was trying to get into server by guessing my password by brute force. what would be the best to stop this attack and how? the server running apache mysql and ftp PORT STATE SERVICE 21/tcp open ftp 80/tcp open http 443/tcp

I am attempting to implement XFS on a new system. System: Supermicro SC846 TQ-R900B - rack-mountable SUPERMICRO X7DWN+ - motherboard 3ware 9650SE-24M8 - storage controller 10 Hitachi DeskStar 7K1000 - hard drive - 1 TB 8GB Ram 2 Intel Quad-Core Xeon E5420 / 2.5 GHz processor Installed Centos 5.1 X86 64 from DVD. System on /dev/sda1 ? 250GB ext3 (raid 5). /home will be on /dev/sdb1 ? over 7TB

I notice that the same versions of kmod-xfs and xfsprogs etc. are in both the extras and centosplus repositories for centos5. Is there any particular reason to use the centosplus kernel if what I'm primarily interested in is XFS filesystem support? I presume that if I am using the plus kernel, then I must use the plus versions of kmod-xfs etc., but I'm wondering whether I need the plus

Hello there, I successfully use automount to mount a large XFS pargtition on one CentOS 5.5 machine. I then tried to do the same thing on a different machine - and it simply would not work! The configuration is done in the same fashion, I checked and double-checked the syntax - but it is still a no go. When I use the mount command the partition mounts perfectly. I have tried running automount

https://fedoraproject.org/wiki/Ovirt_Node_Spin I noticed that virt-manager-tui is in rawhide finally, but the package name implies that it's not going to be in f16? virt-manager-tui.noarch 0.9.0-4.fc17 rawhide Cole, is this intentional or just smth that we need to follow up on? Also, I've noticed that ovirt-node needs refreshing... iirc apevec did tag/release of 2.0.1 from

Hello, I've created a draft for Ovirt Node validation matrix: https://fedoraproject.org/wiki/User:Athmane/Draft_Ovirt_Node_validation_matrix Tomorrow I'll create collectd test case, also I would ask if there's a pre-built iso for testing (I need it to ensure that nothing is wrong with test matrix) otherwise I'll try to compose it. Thanks. -- Athmane Madjoudj

Hello everyone, This is not directly related to CentOS but still: we are trying to set up some storage servers to run under Linux - most likely CentOS. The storage volume would be in the range specified: 8-15 TB. Any recommendations as far as hardware? Thanks. Boris. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi All, we've run into a problem with the xfs component in the centosplus kernel (2.6.9-34.106.unsupportedsmp) where synchronous writes sometimes fail with EAGAIN. It's causing headaches for DB2 installs and for our database research group. There is a fix reported at: http://marc.theaimsgroup.com/?l=linux-xfs&m=110808122904352&w=2 ...that's supposed to take care of

I read that XFS has problems with 4K Stack size for Linux on 32-bit systems. How did we address this in the centosplus kernel? Since what release of CentOS was this problem resolved? Is there a quick way to know what size the Linux stack is configured to be in a system's that's running? Thanks for your help. -------------- next part -------------- An HTML attachment was scrubbed...

Hello all, I am implementing a new mail server into our environment consisting of three machines - two Dell Opterons that will act as load balanced Postfix servers, and a 1.5TB RAID10 NFS server. All three machines are running CentOS 4.5. Since the NFS is going to be used for only mail, I was kicking around the idea to use XFS. I have CentOS installed on an ext3 partition, and with the

Hello listmates, If I have a regular, ACL-capable filesystem on Linux (say, ext4 or xfs) is there a way for me to establish the following: 1) There is a directory, say, /home/joe . It is owned by user joe . No one but joe (and root, of course) can read or write anything in this directory. 2) No one can change permissions on that directory, not even joe. In other words, in joe all of a sudden

Hello listmates, I am wondering if there is a set of scripts/utilities for automatically starting and running headless (no X11) VM's using VirtualBox omn a CentOS 6 server. VNC/RDP access to the VM's would be fine. Any help much appreciated. Cheers, Boris.
