Aug 2 02:42:29 filemaster mdadm[2430]: RebuildFinished event detected on md device /dev/md0, component device mismatches found: 128I was a bit concerned about this, since this array is a 2-drive mirror, and I don't know how to tell which device is correct. I suppose I'll have to just let the kernel fix the mismatches and hope for the best. Google found some pages that say the way to tell the kernel to rebuild the array is:
echo repair >> /sys/block/md0/md/sync_actionI did that, waited for the rebuild to finish, and then initiated a re-check:
echo check >> /sys/block/md0/md/sync_actionHowever, once that finished, the same 128 mismatches were still reported.
I think the way to fix it is to make one of the devices as failed, remove it from the array, then re-add it.
