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 Devices : 2 Total Devices : 2 Preferred Minor : 0 Persistence : Superblock is persistent

Number Major Minor RaidDevice State 0 8 17 0 active sync /dev/sdb1 1 8 33 1 active sync /dev/sdc1
If done some googling but I am stumped as to what would have kicked this off, anyone have any insight that would be great...The system has been up for ~34 days and it kicked off at 4am local time...Here are some of my system details...
Centos 5.5 - 2.6.18-194.11.4.el5
fstab: LABEL=/ / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 /dev/md0 /home ext4 noatime,defaults 0 2 /dev/md0 /mnt/data-raid ext4 noatime,defaults 0 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 LABEL=SWAP-sda2 swap swap defaults 0 0
Thanks in advance....
