script to create /etc/lvmpvg file

[rleon]

Hi everyone ..

Just wondering if  anyone have a script that creates / appends the /etc/lvmpvg file for a specfic vg that is already created?

Thanks

Hi:

I don't have a script to create an '/etc/lvmpvg' file or its stanzas after the fact.  If you are creating a volume group from scratch, simply use the '-g pvg_name' option of 'vgcreate' to form the entry.  Otherwise, you can create the 'lvmpvg' by-hand after the fact from the physical volumes that comprise your volume group, using 'vgdisplay -v'.

See the manpages for 'lvmpvg(4)' and 'vgcreate(1M)' for more information.

Regards!

It can't really be automated, since you're the one who has to decide what disks go in which PVGs, right?  Maybe it should be a feature request for the pvchange command - pvchange -g PVG1 /dev/dsk/c0t0d0, right?

/etc/lvmpvg is a very simple file to edit, though.

VG<tab>/dev/vg00

PVG<tab>GROUPNAME

/dev/dsk/c0t0d0

/dev/dsk/c0t1d0

The key is that the white space between the VG and PVG keys and their values must be a single tab. Spaces won't work.
