How to create the /etc/lvmconf/vgdata.mapfile by OS?

[Rambo_1]

Hi ,
There are some files such as
vgdata.conf
vgdata.conf.old
vgdata.mapfile
under /etc/lvmconf/ . I wonder how&when these files to create by OS ?

Thanks & BR

Rambo,

The vgcfgbackup command will create those files for you. I don't have system access right now so you're best bet is doing a:
man vgcfgbackup

Most commands that make any LVM configuration change will also run the command above to get a backup for you.

I actually schedule a weekly vgcfgbackup to keep the data fresh. It has come in handy a couple of times. The vgcfgrestore command goes hand in hand with it.

The command to create them is vgexport

Man vgexport will tell you how to create the mapfiles.

Hi
vgcfgbackup is the command to create these files.
vgcfgbackup /dev/vg_name will create backup file named /etc/lvmconf/vg_name.conf
But if you want to change the default path use vgcfgbackup -f /tmp/vg_name.conf /dev/vg_name
for updating backup file use vgcfgbackup with -u option.see man pages for more details.
using vgexport command you can create map files.see the followin command
vgexport -m vg_name.mapfile /dev/vg_name.see man vgexport for more details.
