Hi,

I have an issue that I can't really pin down.

I have two RAID 1 arrays, one for /boot and another for an LVM.

Yesterday one of the arrays (the LVM) became degraded after a reboot
which included an automated fsck on all filesystems.

I've run full SMART tests on both drives and both completed without errors:
[SNIP]

I'd really appreciate some advice.

Regards

Hi,

Full SMART Self-test does that mean smartctl -t long? You could try a
nondestructive badblocks session on both drives, but it takes a while.
