tgtd segfault with software RAID, hard resetting link

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This night I had a SATA timeout on a drive in software RAID-1.

It recovered just fine, but unfortunately, tgtd crashed and some of the initiators had I/O errors.

This is how the kernel log looks on the target - everything happened in one second
(SATA timeout, hard reset, tgtd segfault) - is it a known issue? I use tgt-0.9.5.
