backup & restore a volume group

donybangetgitu · #1 (**permalink**) 10-06-2009

Dear All,

I would like to ask about saving & restoring a user defined volume group. i have a user defined volume group, named as datavg. i want to save it & to restore it into different size of physical volume. currently, datavg consist of 4 pv, three fisrt pv size are 100GB & one pv size is 150GB. if i want to restore saved datavg into 4 pv that it each size 100GB, will problem occur? or any consideration to save & to restore my user defined vg? additional info, datavg is 70% used. pls advice.

Thanks

Hi,

you have 2 options:

1. use

Code:

savevg datavg 
restorevg datavg

2. do it without backing up anything:

Code:

extendvg datavg 'newpv'
migratepv 'oldpv' 'newpv' 
reducevg datavg 'oldpv'

Kind regards
zxmaus
