Description Nate Straz 2009-11-05 20:43:58 UTC 
Description of problem:

When there exists a clustered volume group and LVM is configured for local locking, a memory leak message is printed from `pvs`.



Version-Release number of selected component (if applicable):
lvm2-2.02.53-2.fc12.i686
lvm2-cluster-2.02.53-2.fc12.i686


How reproducible:
Every time

Steps to Reproduce:
1. lvmconf --disable-cluster
2. pvcreate /dev/sdb1
3. vgcreate clustered /dev/sdb1
4. vgchange -cy clustered
5. pvs
  
Actual results:

[root@morph-01 ~]# lvmconf --disable-cluster
[root@morph-01 ~]# pvcreate /dev/sdb1
  Physical volume "/dev/sdb1" successfully created
[root@morph-01 ~]# vgcreate clustered /dev/sdb1
  Volume group "clustered" successfully created
[root@morph-01 ~]# pvs
  PV         VG         Fmt  Attr PSize   PFree
  /dev/sda2  vg_morph01 lvm2 a-    37.07G      0
  /dev/sdb1  clustered  lvm2 a-   271.34G 271.34G
[root@morph-01 ~]# vgchange -cy clustered
  Volume group "clustered" successfully changed
[root@morph-01 ~]# pvs

  PV         VG         Fmt  Attr PSize  PFree
  /dev/sda2  vg_morph01 lvm2 a-   37.07G    0
  You have a memory leak (not released memory pool):
   [0x90ecab0]
  You have a memory leak (not released memory pool):
   [0x90ecab0]

Expected results:

No memory leak

Additional info:

The memory leak goes away when cluster locking is enabled.
[root@morph-01 ~]# lvmconf --enable-cluster
[root@morph-01 ~]# pvs
  PV         VG         Fmt  Attr PSize   PFree
  /dev/sda2  vg_morph01 lvm2 a-    37.07G      0

Comment 1 Bug Zapper 2009-11-16 15:10:39 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle.
Changing version to '12'.

Comment 2 Milan Broz 2010-06-22 21:41:07 UTC 
This should be fixed in recent code.
