I have 3 RAID 1 arrays across 2 drives, a RAID 5 drive across 3 drives, and a RAID 0 across 2 drives. I routinely will query smartctrl with something like for i in a b c d e f; do smartctl -a /dev/sd$i | grep Reallocated; done or for i in a b c d e f; do smartctl -a /dev/sd$i | grep Temperature; done Here are the system details cat /proc/mdstat Personalities : [raid1] [raid6] [raid5] [raid4] [raid0] md0 : active raid1 sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md2 : active raid1 sdb3[1] sda3[0] 2032128 blocks [2/2] [UU] md3 : active raid0 sdd1[1] sdc1[0] 625137152 blocks 64k chunks md4 : active raid5 sdg1[2] sdf1[1] sde1[0] 1953519872 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU] md1 : active raid1 sdb2[1] sda2[0] 154151616 blocks [2/2] [UU] lpsci 02:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08) modprobe.conf alias scsi_hostadapter mptbase alias scsi_hostadapter1 mptsas rpm -qa | grep smartmontools smartmontools-5.38-2.el5 uname -r 2.6.18-128.4.1.el5 On Sun, Nov 8, 2009 at 5:59 PM, Richard Scobie wr= ote: > Andrew Dunn wrote: >> >> I am not, but this is quite interesting.
