umount means make not accessible thats all

You won't loose any data, but it will be invisible or inaccessible to the applications, if any using /opt. By the way, what's the necessary for unmounting /opt ?

[Kapil Jha]

befor umounting
fuser -u /opt
will list u users using this file system ask them to close there work.

or
fuser -k /opt
will kill everything related to file system /opt.

in any case data loss is not possiblem.

BR,
Kapil

Hi Ajit,

make sure all the applications running in your system are down ..
Then go ahead..

It seems unlikely to me that you will be able to unmount /opt unless you re-boot into single user mode.

Just something to keep in mind.

You can't umount the /opt in multiuser mode.

In single user mode u can mount the required LV and execute the maintenance task.
