Description Corey Marthaler 2005-07-07 21:03:21 UTC 
Here is the view of my volumes across all three node in the cluster:
[root@link-11 ~]# pvscan
  PV /dev/sda1   VG link101112   lvm2 [135.64 GB / 0    free]
  PV /dev/sdb1   VG link101112   lvm2 [135.64 GB / 0    free]
  PV /dev/sdc1                   lvm2 [135.65 GB]
  PV /dev/sdd1                   lvm2 [135.65 GB]
  PV /dev/sde1                   lvm2 [135.66 GB]
  PV /dev/sdf1                   lvm2 [135.66 GB]
  PV /dev/sdg1                   lvm2 [135.66 GB]
  Total: 7 [949.56 GB] / in use: 2 [271.29 GB] / in no VG: 5 [678.27 GB]
[root@link-11 ~]# vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "link101112" using metadata type lvm2
[root@link-11 ~]# lvscan
  ACTIVE            '/dev/link101112/lvol0' [271.29 GB] inherit


I then delete the lv and vg...
[root@link-11 ~]# lvremove /dev/link101112/lvol0
Do you really want to remove active logical volume "lvol0"? [y/n]: y
  Logical volume "lvol0" successfully removed
[root@link-11 ~]# vgremove link101112
  Volume group "link101112" successfully removed


I then recreate the vg and lv but with less space (one less pv)...
[root@link-11 ~]# vgcreate link101112 /dev/sda1
  Volume group "link101112" successfully created

Now, if I try and create the lv I'll see locking errors when trying to activate,
even if I do a vgscan on all nodes in the cluster before doing so (which I
shouldn't have to do).

[root@link-11 ~]# lvcreate -l 34724  link101112
  Error locking on node link-12: Internal lvm error, check syslog
  Error locking on node link-10: Internal lvm error, check syslog
  Error locking on node link-11: Internal lvm error, check syslog
  Failed to activate new LV.

Jul  7 11:01:09 link-10 lvm[2475]: Volume group link101112 metadata is inconsistent
Jul  7 11:01:09 link-10 lvm[2475]: Volume group for uuid not found:
ECFI1X41UcgAeKJHcw2XjRQSNgxO3QJUGq6hJKATVneajSLqRgfHduc8PiJ3UuwO

Jul  7 11:01:18 link-12 lvm[2469]: Volume group link101112 metadata is inconsistent
Jul  7 11:01:18 link-12 lvm[2469]: Volume group for uuid not found:
ECFI1X41UcgAeKJHcw2XjRQSNgxO3QJUGq6hJKATVneajSLqRgfHduc8PiJ3UuwO

If I then go and lvscan and lvchange on all nodes, it will work, but I shouldn't
have to do that.

Comment 1 Alasdair Kergon 2006-02-01 14:10:12 UTC 
Probably similar to bug 138396.
Comment 2 Alasdair Kergon 2006-02-01 14:34:47 UTC 
What's happening here is one VG is getting deleted then another one created with
the same name, and clvmd is failing to detect and handle this.

Same cause as bug 147361.
Comment 3 Alasdair Kergon 2006-04-21 19:13:27 UTC 
Patch added to cvs that might solve this - will be in 2.02.06.

Comment 9 Corey Marthaler 2006-12-11 21:01:04 UTC 
I can not reproduce this anymore with the latest rpms:
lvm2-cluster-2.02.16-1
lvm2-2.02.16-1

marking verified.
