Here’s another problem I encountered ages ago but figured I’d post about in case someone else encounters the same issue. After mounting an NFS filesystem,  I had run ‘mount’ and noticed the following

host:/#mount | grep db2inst_1
mount: /db2inst_1 has an unknown gfstype (35)

After seeing this I decided to attempt to unmount the filesystem but I came across the following error:

host:/#umount /db2inst_1
umount: /db2inst_1 has an unknown gfstype (35)

After much grief in searching for a solution on google, I remembered that the definition would reside in /etc/vfs. After adding the following entry into /etc/vfs all was well:

nfsv4   35      /sbin/helpers/nfsmnthelp        none            remote

Just thought I would post this as it may come in handy to someone else.

Thanks that really helped me. I almost requested a downtime for reboot. :)
