backup data from different systems where volume groups are duplicated

[kabucek]

hello @LL,

I have couple hard drives from different linux distro's.

on the hdd's are logical volumes created.

what i want to do is to backup the data from those hdd's.

but when I connect some of them and boot up the system it

gives me an error that there are volume group duplicated and it list the UUID.

My host system is centos 5.

What is the best solution to rename those volume groups or to

mount the drives from other systems, so the data will not get lost?

Thanks
