Hello,
As I wrote in #11742 [1] I experienced a kernel panic after doing heavy I/O
on the 1.6.5rc2 cluster on the mds. Since nobody answered to this bug
until now (and I think in other cases the lustre team is _really_ fast
(thanks for that :))) I fear that it was not recognised by anybody.
This kernel-panic seems somehow to be related to the bug mentioned above
(#11742) as this bugnr. is mentioned in the dmesg output when it died.
Furthermore right before it started to fail there were several messages
like the following:
LustreError: 3342:0:(osc_request.c:678:osc_announce_cached()) dirty
81108992 > dirty_max 33554432
This behaviour is described in #13344 [2].
Any ideas?
Greetings
