similar to: mismatch_cnt after 5.3 -> 5.4 upgrade

CentOS 6.3, x86_64. I have noticed when building a new software RAID-6 array on CentOS 6.3 that the mismatch_cnt grows monotonically while the array is building: # cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] md11 : active raid6 sdg[5] sdf[4] sde[3] sdd[2] sdc[1] sdb[0] 3904890880 blocks super 1.2 level 6, 512k chunk, algorithm 2 [6/6] [UUUUUU]

this has never happened to me before, and I'm somewhat at a loss. got a email from the cron thing... /etc/cron.weekly/99-raid-check: WARNING: mismatch_cnt is not 0 on /dev/md10 WARNING: mismatch_cnt is not 0 on /dev/md11 ok, md10 and md11 are each raid1's made from 2 x 72GB scsi drives, on a dell 2850 or something dual single-core 3ghz server. these two md's are in

I've got a fresh CentOS 7 test machine, fully patched. The command: shutdown -h now surprisingly does not halt the machine. Instead it reboots it. WTF? I found the following Debian discussion which seems to be the same issue: <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766338> However, removing kexec-tools in this case did not solve the problem. Nor does

Now don't go bugging people asking when CentOS 6.7 will be out. "When it's ready." In upgrading from RHEL 6.6 to 6.7, I did find that I had to disable my 3rd party repos (elrepo and epel) in order to avoid yum erroring out. Plus I did the usual "yum clean all". (I don't use the PackageKit GUI as it's been unable to complete for quite a few months without

hi, it's been a few weeks since rhel/centos 5.4 released and there were many discussion about this new "feature" the weekly raid partition check. we've got a lot's of server with raid1 system and i already try to configure them not to send these messages, but i'm not able ie. i already add to the SKIP_DEVS all of my swap partitions (since i read it on linux-kernel list

I have a CentOS 6 machine that was initially installed as CentOS 6.4 in May of 2013. It's /boot filesystem is 200M which, IIRC, was the default /boot size at the time. The most recent kernel update (2.6.32-573.18.1.el6) fails because of lack of space in /boot. The workaround is edit /etc/yum.conf, reduce installonly_limit from 5 to something lower (I used 3), remove the oldest kernel via

I noticed that (in a case with a two disk md mirror and lvm), the CentOS 7 installer is now placing /boot as the *last* partition on the disk. I'm assuming that others are seeing this behavior. Does anyone know why it's now the last instead of the first? (Seems to work, though.) Devin

Hi all! I'm still on C6. I'm using a RAID1 configuration (Linux software RAID) and I'd like to either use the same one, or possibly configure it on new drives (larger) when I upgrade to C7. (I'm really feeling the need to move off C6.) But it isn't at all obvious how one would do a new RAID1 setup in Anaconda, and I don't find any user reports or other info on this in the

Does anyone have the magic incantation required to getting *independent* multi-monitors going under CentOS 7? Ideally under xfce or trinity, but I'm interested about GNOME/KDE observations as well. I'm trying to move my main workstation from CentOS5 to CentOS7 and while the spanned desktop works, not having independent monitors really cuts into my productivity. i.e.: I couldn't

It looks like someone pooched a domain transfer, and the whois entry for centos.org is missing its NS records. I've sent an email to the whois tech contact @redhat, but I'm sending this to the list to hopefully bring it to someone else's attention, as well. Hopefully it gets gets out before my mailserver expires its DNS cache for centos.org. Expect centos.org to be offline for a bit

To All, Thanks to the CentOS guys for 5.4; sure appreciate your work. I have one question. I had to remove perl-5.8.8-18.el5_3.1.i386 on two x86_64 machines in order to get perl.x86_64 4:5.8.8-27.el5 to update. Does this represent a change from 5.3 to 5.4 and should I be concerned about the loss of perl-5.8.8-18.el5_3.1.i386. So far I have not found anything broken. Greg Ennis

Ok, trying to bypass the usual flames (I used CDE for years, then KDE until it got dumbed-down too much, and we all know how GNOME has turned out) ... I've decided to try out xfce on CentOS 7. I grabbed xfce from epel by installing the following via yum: epel-release @xfce So far it's pretty good, and is giving me the basic features I'm looking at without getting in my way.

hi all! back in Aug several of you assisted me in solving a problem where one of my drives had dropped out of (or been kicked out of) the raid1 array. something vaguely similar appears to have happened just a few mins ago, upon rebooting after a small update. I received four emails like this, one for /dev/md0, one for /dev/md1, one for /dev/md125 and one for /dev/md126: Subject: DegradedArray

I'm using the MATE desktop (via 'yum groupinstall "MATE Desktop"') on CentOS 7. I'm finding the mouse to be rather flakey in the sense that: - in MATE Terminal, clicking on text and dragging the mouse (in order to highlight the text and copy it to the X cut & paste buffer) will sometimes drop the highlight (thus not copying anything), or stop and

dmesg is not reporting any issues. The /proc/mdstat looks fine. md0 : active raid1 sdb1[1] sda1[0] X blocks [2/2] [UU] however /var/log/messages says: smartd[3392] Device /dev/sda 20 offline uncorrectable sectors The machine is running fine.. raid array looks good - what is up with smartd?
