RedHat No space in volume group. How to create a file system using existing logical volume

Hello Guys,

I want to create a file system dedicated for an application installation. But there is no space in volume group to create a new logical volume. There is enough space in other logical volume which is being mounted on /var.

I know we can use that logical volume and create a virtual file system. Unfortunately I couldn't recollect the procedure.

Scenario:
/dev/vg00/lvvar is mounted on /var

I want to use the same logical volume lvvar to create another file system /patrol without dismounting /var. Please let me know the complete procedure..


Thanks in advance Smilie

NAME
lvremove - remove a logical volume SYNOPSIS
lvremove [-A|--autobackup {y|n}] [-d|--debug] [-h|--help] [-t|--test] [-v|--verbose] [--version] [-f|--force] [--noudevsync] LogicalVol- ume{Name|Path} [LogicalVolume{Name|Path}...] DESCRIPTION
lvremove removes one or more logical volumes. Confirmation will be requested before deactivating any active logical volume prior to removal. Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem). Removing an origin logical volume will also remove all dependent snapshots. If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com- mand issued from one node can do this. OPTIONS
See lvm(8) for common options. -f, --force Remove active logical volumes without confirmation. --noudevsync Disable udev synchronisation. The process will not wait for notification from udev. It will continue irrespective of any possible udev processing in the background. You should only use this if udev is not running or has rules that ignore the devices LVM2 cre- ates. EXAMPLES
Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation: lvremove -f vg00/lvol1 Remove all logical volumes in volume group vg00: lvremove vg00 SEE ALSO
