next in thread | raw e-mail | index | archive | help
I recently updated all of our FreeBSD3 clients to use NFSv3/UDP when
contacting our servers (FreeBSD3 of the same build tree). We have
noticed an increase in crashing of our main home directory server
(which is the only server really handling RW mounts, our other servers
are mostly RO, with some minor RW activity.) The first crash was
obviously NFS. I traced it to one of 2 possible crash points in the
kernel (sorry, no stack trace, we don't [yet] have a crashlogs enabled
for that machine.).
The panic was:
mbuf siz=33476
panic: Bad nfs svc reply
The second panic just happened, it claims to be softupdate related. I
think it may have something to do with NFSv3 however since this machine
used to be very stable (ie, not 2 crashes in a week).
This panic was:
panic: softdep_write_inodeblock: indirect pointer #0 mismatch 0 != 102192
8
syncing disks... panic: softdep_lock: locking against myself
Here is some dmesg output for your amusement ;)
