Description Dave Wysochanski 2008-06-03 20:27:17 UTC

Description of problem:

Allowing the vg* commands to take a UUID as input would be very useful,
especially virtualized setups.  This is a bz to track all relevant commands. 
Currently AFAIK only vgrename allows a UUID.  To start, I will focus on vgremove
but probably common code will be modified.

Comment 2 Alasdair Kergon 2013-10-22 12:30:31 UTC

From bug 1021715: "it would suffice to add this ability to lvs, vgchange, and vgremove."

Comment 3 David Lehman 2013-10-22 16:41:47 UTC

In case it will help motivate you to fix this, see bug 1015474 for one example of a bug reported against anaconda related to this bug. There have been many dozens of such bugs over the years. Please fix this.

Comment 4 Peter Rajnoha 2015-09-24 14:01:26 UTC

We have -S|--select now - it should be possible to specify UUIDS instead of names using:

  lvs/vgchange/vgremove --select 'uuid=...'

I need to check if it works fine with lvmetad though...

Comment 5 Peter Rajnoha 2015-10-05 10:58:16 UTC

I think we can close this one as requested functionality is available by using the -S|--select now with the vg_uuid or lv_uuid specified as selection criterion. Support for using selection for reporting commands is available since lvm2 v2.02.107 and for other processing commands (like vgchange/lvchange/vgremove etc) is available since lvm2 v2.02.117:
