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. Only thing I find in dmesg (but I am not sure what to search for) klaus@raagi:~> sudo dmesg | grep " md" [ 4.131071] md/raid1:md127: active with 2 out of 2 mirrors [ 4.282183] md127: detected capacity change from 0 to 4000261472256 [ 64.407382] md: data-check of RAID array md127 [21681.409218] md: md127: data-check interrupted. [25477.760407] md: data-check of RAID array md127 [47096.271827] md: md127: data-check interrupted. I left the PC running after reboot, so I am not sure why the data-check was interrupted. Any ideas on why it has started to rebuild after every reboot? -- Cheers Klaus
