Description

We have experienced an LBUG today on one of our OSS servers which I have not seen before.

LustreError: 16066:0:(filter_io_26.c:344:filter_do_bio()) ASSERTION(rw == OBD_BRW_READ) failed
LustreError: 16066:0:(filter_io_26.c:344:filter_do_bio()) LBUG
Pid: 16066, comm: ll_ost_io_126

Now after rebooting that OSS same LBUG is triggered as soon as OSTs finish recovery and start servicing their data. Has anyone seen this before ?

Our environment:
servers: RHEL6 2.6.32-220.17.1.el6_lustre.x86_64 Lustre-2.1.2
clients: RHEL6 2.6.32-358.6.2.el6.x86_64 Lustre-2.1.5 patchless
