Hi All, I have a very strange problem that I'm unable to pinpoint at the moment. For some reason I am simply unable to get xfs_quotas to report correctly on a freshly installed, fully patched CentOS 6 box. I have specified all the same options as on another machine which *is* reporting quota LABEL=TEST /exports/TEST xfs inode64,nobarrier,delaylog,usrquota,grpquota 0 0 xfs_quota -xc

Hi All, I''m trying to write some plugins that should only be sync''d if they''re for a specific platform. For example, in our environment we''re supporting Solaris, Ubuntu, Fedora, CentOS and Mac OS X. We''ve developed some OS X plugins and some Solaris plugins but we''ve noticed that our Linux hosts have imported our OS X plugins and now throw

Hi, I need to create a real-time replication of a partition between two servers with centos 6.4, I am researching and finding difficulty with drbd, corosync, someone indicate material, do not need to run script automatically if a node drops only replicate. Grateful. -- Sergio.Alex

Hi All. I currently have a problem on my backup server with very large number of small files in a large number of directories. I would like to delete them as fast as possible. Currently I use: rsync -a --delete /empty_directory/ dir_to_clean/ I've read that rsync will be faster than rm or find. Can you recommend something? I use an ext4 filesystem. Best regards, Rafal.

Hey All, What's with this? google-chrome-stable-28.0.1500.45-205727.i386 requires libstdc++.so.6(GLIBCXX_3.4.15) : Success - empty transaction I got a software update notice that offered google-chrome, but when I tried to install the update I got a dependency issue. Is this a bug in the package or is it time to give up on Chrome? -- _ ?v? /(_)\ ^ ^ Mark LaPierre

Hey, any puppet user on CentOS 5 using puppet lab's repository...? I installed their el5 repository but a puppet install asks for: ruby >= 1.8.7 which is only available on CentOS 6... Someone using their repo? Or do you use the repoforge one...? Thx, JD

Hi all, I was recently poking more into the inode64 mount option for XFS filesystems. I seem to recall a comment that you could remount a filesystem with inode64, but then a colleague ran into issues where he did that but was still out of inodes. So, I did more research, and found this posting to the XFS list: http://oss.sgi.com/archives/xfs/2008-05/msg01409.html So for people checking the

I asked here a week or so ago, and referenced an older bug, but haven't seen any comments. Googling, I see others asking about the same. Datum: *every* one I've found is like this: they're all HP DL580's or DL380's, or such. This is being used for heavy-duty scientific computing. Does anyone know if it *will* it seriously affect throughput speed if I turn off irqbalance?

Hi all, i have a new setup where the htdocs directory for the webserver is located on a nfs share. Client has cachefilesd configured. Compared to the old setup (htdocs directory is on the local disk) the performance is not so gratifying. The disk is "faster" compared to the ethernet link but the cache should at least compensate this a bit. Do they exist more pitfalls for such

I am the IT Development Specialist for a small community college and our CIO has asked me to explore an alternative to Microsoft Active Directory as we are separating from our parent university and funding is tight so we were looking into CentOS with 389 Directory Server. Any advise or suggestions would be very helpful. Jacob Tennant

Hi, We have on an old Dell 2850 with 4 SCSI drives, where we put a Hardware RAID5 on 3 disks and left 1 as spare. I dont remember exactly, but the RAID was setup in the BIOS, and when installing CentOS6, I just saw "1 drive". If it was software RAID, disk failure could be seen in /proc/mdastat, and I could simulate failure with mdadm. As far as it is hardware ATM, how, at least, to

Hi, I was wondering, why/when it is useful or when should I avoid to use LVM. I think the big advantage of LVMing is if you modify (rezising, ...) disk and filesystem layouts "a lot". Are there any real pros or cons for following situations regarding e.g. management and speed? e.g.: I do have a server system raid for which the disk layout will not change; e.g. /var /usr /home will

I have a Centos 5 machine which I've just compiled the 3.10.4 kernel on (remembering to set CONFIG_SYSFS_DEPRECATED) because I needed new rtlwifi drivers for my rtl8192cu device. So far, so good. It seems to work. Except /proc/bus/usb doesn't exist anymore. USB_DEVICEFS has been removed. An older kernel (3.2.9) says Usbfs entries are files and not character devices; usbfs

Can anyone comment on the use of 3rd party repos for newer versions of software like php, python and mysql? Two I am aware of are puias and ius. Is one preferable to the other? Can their packages be installed in parallel to and without interfering with base packages?

Is there a way on Dell R320 (two power supplies and hardware RAID-1) on centos to get a message that a power supply is failing or that one of the hardware RAID disks is failing? Sure there is the front panel - but no-one is there ... Is that reported to linux/centos some way? This is my first R320. Thanks, Jerry

Hello all, I''m trying to figure some things out with SSL and would appreciate some help or best practices here. I''m implementing auto scaling over Amazon EC2 for some services I have, all of the instances are based on the same AMI and I''m using Puppet to configure the hosts when they come up to make sure they have the latest configuration, also I''m using

I'm looking for direction to install and boot CentOS 7 from an iSCSI device. Any experience and advice will be greatly appreciated. Thanks! Michael Duvall

I have a system running CentOS 6.3, with a SCSI attached RAID: http://www.raidweb.com/index.php/2012-10-24-12-40-09/janus-ii-scsi/2012-10-24-12-40-59.html For disaster recovery purposes, I want to build up a spare system which could take the place of the server hosting the RAID above. But here's what I see: # fdisk -l /dev/sdc WARNING: GPT (GUID Partition Table) detected on

Maybe I missed something, but it appears that the CR repository is not compatible with yum priorities & possibly repository protection. I had priority=1 set on [base] and [updates] and no updates appeared. However, when I removed priority updates from cr became visible. Is this expected? Did I miss this announcement on -devel or such because I searched but couldn't find it. -- James
