Package: nfs-kernel-server Version: 1:1.2.2-4 Severity: grave Justification: renders package unusable
Hi there, appologies if this has already been reported but I couldn't see anything quite matching what I'm seeing. I have a 26TB debian squeeze fileserver providing NFS mounts to a large number of users. The system has been working flawlessly for a number of months but twice in the last week NFS seems to have crashed. The first thing I noticed is that users reported being unable to access shares. Logging into the system I see a single nfsd process taking 100% CPU with a very long run time. Restarting nfs-kernel-server has no effect. The process is unkillable (even with -9) and the system has required a reboot to get it usable again. jnettop is not showing significant network traffic and lsof on /export/ (where all my NFS exports are located) shows no nfs access to any files. Please let me know if you need any further information. I am going to reboot the server now, so I may not be able to reproduce the problem straight away (but as its happened twice, I am quite sure it will happen again at some point...). Thanks in advance for your help. Dan Tomlinson My /etc/exports file is below: # /etc/exports: the access control list for filesystems which may be exported # to NFS clients.
