yes - it still happens (happened) with trusty. I use a backup program called backintime which uses rsync, and I backup the laptop to an nfs4 mount. During the backup, the nfs4 server crashes just as specified above in trusty (kernel 3.13.0-32-generic). The backup program then stops, leaving the rsync running.
If I restart the server, without restarting the client, the backup program continues and corrupts the disk that is being backed up to, requiring an fsck. >From the logs of backintime, the command is:- (where pio is the laptop being backed up, mike is the nfs4 server, and the disk /media/seagate on mike is mounted nfs4 at pio as /media/mike/seagate rsync -rtDH --links --no-p --no-g --no-o --delete --delete-excluded -v --chmod=Du+wx --exclude="/media/mike/seagate/backintime" --exclude="/home/kit284/.local/share/backintime" --include="/home/kit284/" --include="/home/" --include="/home/mythtv/" --exclude="*.backup*" --exclude="*~" --exclude="/home/kit284/root" --exclude="/home/kit284/tmp" --exclude="/home/kit284/Ubuntu One" --exclude="*.thumbnails" --exclude="*.iso" --exclude="/home/kit284/.gvfs" --exclude="[Cc]ache*" --include="/home/kit284/**" --include="/home/mythtv/**" --exclude="*" / "/media/mike/seagate/backintime/backintime/pio/kit284/1/new_snapshot/backup/" I am currently running backintime via a FUSE mounted ssh connection built in to backintime, and this is working OK. However, is is very disquieting to know that NFS4 can crash, and take out the disk, requiring a reboot and fsck. I note that some research on the internet show that rsync can have problems with change attributes on nfs4 mounts, and the suggestion is that this is a bug with nfs4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1353730 Title: nfs4 daemon crashes, eventually PC locks up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1353730/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
