Title:
NFS lockup (readonly udp nfsv4 gigabit)
Status in “linux” package in Ubuntu:
Expired
Bug description:
I've got a 12.04 precise client with lots of mounts like this.
morgul:/n2 on /n2 type nfs
(ro,udp,nolock,vers=4,addr=192.168.10.212,clientaddr=192.168.10.216)
morgul:/n1 on /n1 type nfs
(ro,udp,nolock,vers=4,addr=192.168.10.212,clientaddr=192.168.10.216)
Periodically, they all lock up, stuck until reboot. Some processes
(df) stuck like that respond to ctrl-C, others don't (ls)
Networking is fine, and interestingly I can remount the export from
the server on another path on the same client and the new mount works
fine, while all the old ones are still stuck. No useful messages in
syslog.
The server is runnig oneiric, 64 bit.
This seems like a recurrence of NFS bugs that people have reported
before, which have been claimed to be fixed. Its clearly not. I get it
randomly after transferring a few GB of data. (mythtv playback)
