Re: Error in umount an ignite logical volume
You need to install lsof to find which process has it open.
Are you exporting this filesystem?

Re: Error in umount an ignite logical volume
>/usr/local/bin/lsof /var/opt/ignite/recovery
Ok, it doesn't find anything.
>I hadn't exported filesystem.
Then how were you going to make it an ignite server?
>don't know anything about share(1m)
What's in /etc/dfs/sharetab?

Re: Error in umount an ignite logical volume
Also there is an entry under dfstab file
root @ TEST: />cat /etc/dfs/dfstab
# place share(1M) commands here for automatic execution
# on entering init state 3.
#
# share [-F fstype] [ -o options] [-d "<text>"] <pathname>
# .e.g,
# share -F nfs -o rw=engineering -d "home dirs" /home
share -F nfs -o anon=2 /var/opt/ignite/clients

Re: Error in umount an ignite logical volume
>/var/opt/ignite/clients - nfs anon=2
What does "bdf /var/opt/ignite/clients" show?
(It's not exactly the filesystem in question, so it could be just /var.)

Re: Error in umount an ignite logical volume
If you can't figure out who is mounting it, you could try to unmount it with:
umount -f /dev/vg01/lvol7
