Description David Robinson 2007-03-15 07:50:18 UTC 
Description of problem:

LVM2 is unable to import striped LVM1 volumes. The following error is produced:

  LV testLV: inconsistent LE count 4 != 6
  Internal error: LV segments corrupted in testLV.
  Volume group "test" not found

Non-striped volumes import correctly - striping is the key.

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

Versions of LVM2 > 2.2.01.08 are unable to import striped LVM1 volumes.
LVM-2.2.01.08 (RHEL4 U1) works, but LVM-2.2.01.14 (RHEL4 U2) and later are
broken. The problem exists in RHEL4 U4, and RHEL5.

How reproducible:
100%

Steps to Reproduce:
1. Make a block device (sdb in this example) available to RHEL3 (any update).
2. pvcreate /dev/sdb
3. vgcreate testVG /dev/sdb
4. lvcreate -L 100M -i 2 -n testLV testVG
5. mkfs.ext3 /dev/testVG/testLV
6. Move the block device to a RHEL4 >= U2 system (LVM-2.2.01.14).
7. Any LVM commands will cause the errors below, and you won't be able to
activate the volume group - it will not exist.

Actual results:

# lvscan
  LV testLV: inconsistent LE count 4 != 6
  Internal error: LV segments corrupted in testLV.
  Volume group "testVG" not found
  ACTIVE            '/dev/VolGroup00/LogVol00' [2.28 GB] inherit
  ACTIVE            '/dev/VolGroup00/LogVol01' [512.00 MB] inherit

Unable to access the LV.

Expected results:

# lvscan 
  ACTIVE            '/dev/test/test_lv' [192.00 MB] normal
  ACTIVE            '/dev/test/test2_lv' [192.00 MB] normal
  ACTIVE            '/dev/VolGroup00/LogVol00' [3.25 GB] inherit
  ACTIVE            '/dev/VolGroup00/LogVol01' [512.00 MB] inherit

Able to access the LV.
