My colleague made a mistake and gave:
mount -t nfs freenasip:\mnt\backup \mnt
on FreeNAS server itself instead of other server where it was to be mounted. Immediately he ran:
umount freenasip:\mnt\backup
but it hanged. Now both mount -a and zfs mount -a on FreeNAS show correct info but cd /mnt/ or any folder inside /mnt hangs at the prompt. Also, file sharing and NFS mounting to external server issue. Is there any way to resolve the issue without a reboot?
I have iscsi targets service running in it so have to wait for all servers to shutdown and then reboot FreeNAS which will resolve the issue. Is there another solution for same?
