[CentOS] 6.2 - How to check for a failed disk using LVM with a hardware RAID (3ware)
CentOS Community, What commands can I use to check the disk health of the system when LVM2 is being used on top of a RAID 10 using a HARDWARE 3ware raid card. The OS sees a hardware raid usually as one big drive. Is there a way to check the disks individually to see if any are failing, or throwing hard or scsi transport errors?

I've a 3ware Raid-Kontroller with Linux-Software (cmd-line and Web-gui) to contoll and manage the controller. Just look at the website of 3ware. Gru?

With this you can check the health of the raid and its disks: # tw_cli /c0 show Unit UnitType Status %RCmpl %V/I/M Stripe Size(GB) Cache AVrfy ------------------------------------------------------------------------------ u0 RAID-10 OK - - 256K 1862.62 ON OFF Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 OK u0 931.51 GB 1953525168 WD-WMATV4882192 p1 OK u0 931.51 GB 1953525168 WD-WMATV4911813 p2 OK u0 931.51 GB 1953525168 WD-WMATV4884633 p3 OK u0 931.51 GB 1953525168 WD-WMATV4881597 p4 NOT-PRESENT - - - - p5 NOT-PRESENT - - - - p6 NOT-PRESENT - - - - p7 NOT-PRESENT - - - - Regards, Dennis

You can automate the checks by configuring /etc/smartd.conf using lines like: /dev/twa0 -d 3ware,0 -H -l selftest -l error -o on -S on -s (O/../../6/22|S/../../1/2|L/../../2/1) -m root at yourdomain.com Remember to comment out the default line (the first line of /etc/smartd.conf). -- Benjamin Franz
