Subject: MD RAID1 deadlock on failed disk
Date: Tue, 26 Oct 2010 22:32:21 GMT [thread overview]
Message-ID: <0AFDL9Y11@briare1.fullpliant.org> (raw)
Hi,
The configuration is:
Perc H200 controler configured with no RAID (mpt2sas driver),
2 SATA disks (sda and sdb),
Linux MD Sofware RAID1 (md0),
stock Linux 2.6.35.7 kernel.
I hotunplug the second (sdb) disk, and the result is:
. as expected, I can read sda device,
. as expected, any read to sdb device fails,
. unexpectedly, and read to md0 never returns.
No oops or thing like that in the kernel log.
I did not try the same with other kernel releases.
Regards,
Hubert Tonneau
