[linux-lvm] Importing a VG with existing name

[Oliver Tennert]

Hello,

can anybody tell me what the best way is to import a volume group, when the 
vg's name already exists in the system?

Many Linux installations (like Fedora or RedHat) use default names for volume 
groups. Whenever the issue arises to access the VGs from another system, 
trying to imprt the VG leads to an inconsistent LVM database.

I failed to rename the still exported VG, which is already plugged into 
thethis leads to a wrong checksum.

So: what is the best solution?

Best regards

Oliver Tennert

Version 2.02.05 lets you rename it by giving its uuid to vgrename
in place of its name.

Prior to that you can set up a one-off lvm.conf file with filters that
exclude everything except the disk(s) being imported and use the
LVM_SYSTEM_DIR environment variable to point lvm at the temporary
configuration file.
