Re: RAW F/S Creation

Just use lvcreate to create your new LVOLs.

No need to create a file system (newfs) if you want to use them as raw devices.

Hope this helps!

Re: RAW F/S Creation

First you must delete 'lrvol191' using lvremove.

Then - as has been stated above - you can use
the freed up space to create new vols.
