Forget the afforementioned error. The problem that I have is now when I issue a df(1) my shell hangs: e.g. # df -h ^C^C^D ^C^C^D # ps -aux | grep df username 3333 0.0 0.0 212 96 p2 D+ 9:04AM 0:00.00 df -h username 3332 0.0 0.0 212 96 p1 D+ 9:04AM 0:00.00 df -h # kill -9 3333 3332 # ps -aux | grep df username 3333 0.0 0.0 212 96 p2 D+ 9:04AM 0:00.00 df -h username 3332 0.0 0.0 212 96 p1 D+ 9:04AM 0:00.00 df -h No change. I'm not sure what has hung here, nor am I sure how to 'un-hang' my shell. Any thoughts anyone ? - aW To follow up to my own question, an NFS server not responding .... DOH ! - aW To follow-up again, why doesn't this work ? # sudo umount -v -t nfs -f /cdrom/ports/distfiles Just hangs. Surely you can force an un-mount of an NFS filesystem ? - aW
