Hi.
I use a retired office pc with core i5 with as a NAS. I have dropped in 2 disks (3.5T sata) and configured as md raid1 and with lvm on top. It has worked flawless for a year or so, but now after the latest 2 reboots it has triggered a raid rebuilding. Re-reading my own mail I noticed that md says "data-check" and not "rebuilding" I was not aware there was such a thing. Searching the interwebs I found that there is a difference, it is not rebuilding - although /proc/mdstat looks more or less the same as during a rebuild.
klaus@raagi:~> sudo dmesg | grep " md" ... [ 64.407382] md: data-check of RAID array md127 [21681.409218] md: md127: data-check interrupted. ... Any ideas on why it has started to rebuild after every reboot?
One obvious question. Have you checked that the disks are showing good status with no errors? Yes, I'd expect to get some warnings anyway but a specific test might be wise. Yes SMART declares both drive healthy. SMART overall-health self-assessment test result: PASSED
So now I just need to find out why the integrity check is interrupted. -- Thanks Klaus
