Description Corey Marthaler 2007-06-28 16:35:38 UTC

Description of problem:
Currently if you try to split out all the pvs from a vg with out much space left
in the pvs, you'll get the following error:
"Cannot split: Nowhere to store metadata for new Volume Group"

[root@taft-01 ~]# pvscan
  PV /dev/sdb3   VG stripe_3_1422   lvm2 [90.82 GB / 0    free]
  PV /dev/sdb2   VG stripe_3_1422   lvm2 [90.82 GB / 48.00 MB free]
  PV /dev/sdb1   VG stripe_3_1422   lvm2 [90.82 GB / 52.00 MB free]
[root@taft-01 ~]# vgsplit stripe_3_1422 split_65 /dev/sdb3 /dev/sdb2 /dev/sdb1
  Cannot split: Nowhere to store metadata for new Volume Group


Version-Release number of selected component (if applicable):

In lvm2-2.02.30-1.el5.

Comment 5 Corey Marthaler 2008-03-31 19:29:09 UTC

The fix for this bug has been verified in lvm2-2.02.32-2.el5, however I'm
curious about an extra message that is given when running this cmd.

[root@hayes-03 ~]# vgsplit corey feist /dev/etherd/e1.1p[123456]
  Logical volumes in "corey" must be inactive
[root@hayes-03 ~]# vgchange -an corey
  0 logical volume(s) in volume group "corey" now active

# Why is 'Volume group "feist" not found' reported, should that 
be a new bug?
[root@hayes-03 ~]# vgsplit corey feist /dev/etherd/e1.1p[123456]
  Volume group "feist" not found
  New volume group "feist" successfully split from "corey"
