[Lustre-discuss] kernel panic with 1.6.5rc2 on mds

[Patrick Winnertz]

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
Patrick Winnertz
