Hello, I have a RAID5 array on my CentOS 5.6 x86_64 workstation which "suddenly" failed to work (actually after the system could not resume from a suspend). I had recently issues after moving the workstation to another office, where one of the disks got accidently unplugged. But the RAID was working and it had reconstructed (as far as I can tell) the data. After I replugged the disk,

Sorry, this is going to be a rather long post...Here's the situation; I have 4 IDE disks from an old snap server which fails to mount the raid array. We believe there is a controller error on the SNAP so we've put them in another box running CentOS 5 and can see the disks OK. hda thru hdd looks like this Disk /dev/hdd: 185.2 GB, 185283624960 bytes 255 heads, 63 sectors/track, 22526

Hello. I have several systems (CentOS 3 and CentOS 4) with software raid and I've observed a difference in the raid state: In CentOS 3 systems we find that mdadm --detail /dev/md* show: .............. Version : 00.90.00 Creation Time : Fri Apr 16 14:59:43 2004 Raid Level : raid1 Array Size : 20289984 (19.35 GiB 20.78 GB) Device Size : 20289984 (19.35 GiB 20.78 GB)

I am running software RAID1 on a somewhat critical server. Today I noticed one drive is giving errors. Good thing I had RAID. I planned on upgrading this server in next month or so. Just wandering if there was an easy way to fix this to avoid rushing the upgrade? Having a single drive is slowing down reads as well, I think. Thanks.

So still coming up to speed with mdadm and I notice this morning one of my servers acting sluggish...so when I looked at the mdadm raid device I see this: mdadm --detail /dev/md0 /dev/md0: Version : 0.90 Creation Time : Mon Sep 27 22:47:44 2010 Raid Level : raid10 Array Size : 976759808 (931.51 GiB 1000.20 GB) Used Dev Size : 976759808 (931.51 GiB 1000.20 GB) Raid

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

Hello, I had a scientific linux 3.0.4 system (rhel compatible), with 3 ide disks, one for / and two others in linear raid (250 gb and 300 gb each). This system was obsoleted so i move the raid disks to a new scientific linux 3.0.7 installation. However, the raid array was not detected ( I put the disks on the same channels and same master/lsave setup as in the previous setup). In fact

I just installed CentOS 5.4 64 bit release on a 1.9ghz CPU with 8gB of RAM. It has 2 Western Digital 1.5TB SATA2 drives in RAID1.

I have a raid1 array which is somehow faulty. There is 1,5 TB of stuff, I would not want to lose it (though I have full backup). The array cannot be mounted on startup (error message was "missing superblock"). I had to boot from DVD with linux rescue and remove the array from fstab. Here is some info - I am a little dumbfounded. [root at a134-224 log]# cat /proc/mdstat (...) md5 :

Going through the examples and reading through the wiki's I still have not found exactly what I was looking for in matching uid's and gid's. using samba samba3-3.0.32-36 We currently have a domain controller Samba/LDAP PDC. samba-3.0.20b-1 Previous member servers samba-3.0.10-1.4 and I went to add a member server. Now I find that users and groups don't match. So from

Hi, I just replaced Slackware64 14.1 running on my office's HP Proliant Microserver with a fresh installation of CentOS 7. The server has 4 x 250 GB disks. Every disk is configured like this : * 200 MB /dev/sdX1 for /boot * 4 GB /dev/sdX2 for swap * 248 GB /dev/sdX3 for / There are supposed to be no spare devices. /boot and swap are all supposed to be assembled in RAID level 1 across

Hi,we have Centos 5.4 server and according to me we have strange problem. Disk size and other indormation like below.Normally,md2 partition should have 46GB free disk size but available value is zero.Why it show zero ?

For me getting a member server to work I did not need winbind just ldap was sufficient. Did you made the trust account? Getent group and passwd must give you all users and groups. You must be able to chmod domainuser:domaingroup on your Member Server. What I recognized is that the member server with samba 3.028 is much to slow. It takes too long if you try to connect over My Network Places. This

Hi Niki, md127 apparently only uses 81.95GB per disk. Maybe one of the partitions has the wrong size. What's the output of lsblk?
