The following is only the installation record
1. create an lv
[Root @ Linux ~] # Lvcreate-L 20480 VolGroup_ID_25519-n lvdbra
Logical volume "lvdbra" created
2. create a mount point
[Root @ Linux ~] # Mkdir/dbra
3. an error is reported when mounting directly or mounting in ext3 format.
[Root @ Linux ~] # Mount/dev/VolGroup_ID_25519/lvdbra/dbra
Mount: you must specify the filesystem type
[Root @ Linux ~] # Mount-t ext3/dev/VolGroup_ID_25519/lvdbra/dbra
Mount: wrong fs type, bad option, bad superblock on/dev/VolGroup_ID_25519/lvdbra,
