Public bug reported: Binary package hint: nfs-kernel-server
Twice in the past six months this box has experienced a kernel panic. There are two active client machines. The nfs exports are of a drbd (protocol C) mounted device formatted ext4 on an underlying 3ware 9650SE-16ML with 10 2TB WD RE4 SATA drives for a total of ~9TB. The networking includes an 4x LACP bonded network device. (Overkill, in hindsight.) CPU was fairly low at ~10%. There are no logs of the event, but we did snap a picture with a phone: http://geekomatic.ch/images /nfsd-goes-boom.jpg As I expect this to occur again at some point, I'm going to tweak the console settings in hopes of catching more information. Even peak loads are not that high...so adding some debug logging is an option. Let me know. Dropping the LACP is an option.
