MPT2SAS deadlocking on failed disk

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

 



Hi,

In stock Linux 2.6.35.7 kernel,
with mpt2sas driver connected to two disks (no raid at controler level),
and Linux MD software RAID1,

if I hot unplug one of the disks,
instead of the failed disk beeing removed from the MD raid set,
I get locked disk subsystem with all applications trying to write to
the disks beeing locked. No kernel message related to disks, only
to applications beeing locked.

This bug is probably not related specificaly to kernel 2.6.35.7
because I had not used LSI controlers for years.

Regards,
Hubert Tonneau
