I have a particular network share that's giving me grief. Basically, we had two NAS devices which had to be moved to another building. I updated /etc/fstab to the new IP addresses and tried to remount them. One of the NAS devices went through the process just fine. The other one, however, is being rude.
I tried the suggestions in this thread, but they didn't work:
When I type
umount -f /mnt/gsrnas2, it says
Device is busy
If I try to
cd /mnt/gsrnas2 and then
ls, the terminal locks up and I can't break out with Ctrl+C
When I try
fuser -mk /mnt/gsrnas2 or lsof |
grep /mnt/gsrnas2, the terminal freezes with those commands as well.
All of the other NFS mounts on the server are behaving just fine, and I can umount and mount them without any problems.
I'm sure that no one is actively using this mount point, because it points to an unoccupied IP address.
