Hi, what is the output of 'cat /proc/mdstat' ? A healthy raid should look something like below : [root at janeway ~]# cat /proc/mdstat Personalities : [raid1] md2 : active raid1 sdb1[0] sda1[1] 256896 blocks [2/2] [UU] md0 : active raid1 sdd1[0] sdc1[1] 1465135936 blocks [2/2] [UU] md3 : active raid1 sdb3[1] sda3[0] 730218432 blocks [2/2] [UU] I have 3 RAID1 arrays (over 4 disks) On Thu, 2011-04-28 at 21:10 +0200, Alexander Farber wrote: > Additional info (how many RAID arrays do I have??): > > # mdadm -D /dev/md3 > /dev/md3: > Version : 00.90 > Creation Time : Sat Mar 19 22:53:25 2011 > Raid Level : raid1 > Array Size : 185151360 (176.57 GiB 189.59 GB) > Used Dev Size : 185151360 (176.57 GiB 189.59 GB) > Raid Devices : 2 > Total Devices : 2 > Preferred Minor : 3 > Persistence : Superblock is persistent > > Update Time : Thu Apr 28 21:09:12 2011 > State : clean, resyncing > Active Devices : 2 > Working Devices : 2 > Failed Devices : 0 > Spare Devices : 0 > > Rebuild Status : 38% complete > > UUID : 1b3668a3:4b6c5593:3d186b3c:53958f34 > Events : 0.15 > > Number Major Minor RaidDevice State > 0 8 6 0 active sync /dev/sda6 > 1 8 22 1 active sync /dev/sdb6 > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
