This article explains how to create a new volume on your server.
You can change the partitioning according to your wishes.
Please note: This article describes deep changes to your server's file system. We therefore strongly recommend that you create a data backup before you start making these changes.
For example, create a logical volume with 20 GB and the name lv00 within the VolumeGroup vg00:
s12345678 ~]# lvcreate -L 20G -n lv00 vg00 Logical volume "lv00" created
Now create a file system (file system) on the volume with e.g. mkfs.xfs.
s12345678 ~]# mkfs.xfs /dev/vg00/lv00 meta-data=/dev/vg00/lv00 isize=256 agcount=16, agsize=327680 blks = sectsz=512 attr=0 data = bsize=4096 blocks=5242880, imaxpct=25 = sunit=0 swidth=0 blks, unwritten=1 naming =version 2 bsize=4096 log =internal log bsize=4096 blocks=2560, version=1 = sectsz=512 sunit=0 blks, lazy-count=0 realtime =none extsz=4096 blocks=0, rtextents=0
Now mount the partition as usual:
s12345678 ~]# mkdir /lv00 s12345678 ~]# mount -t xfs /dev/vg00/lv00 /lv00
