1660625 – The pvcreate command fails with "Metadata location has invalid summary for VG" error

RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description jhouston 2018-12-18 20:39:36 UTC

Description of problem:

Unable to see PV after reboot.

While attempting a restore of metadata seeing failure:

# pvcreate --uuid="<UUID>" --restorefile  /etc/lvm/backup/vg /dev/sdx
  Couldn't find device with uuid <UUID>.
  /dev/sdx: Checksum error at offset 7168
  Couldn't read volume group metadata from /dev/sdx.
  Metadata location on /dev/sdx at 7168 has invalid summary for VG.
  Failed to read metadata summary from /dev/sdx
  Failed to scan VG from /dev/sdx

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

lvm2-2.02.180-10.el7_6.2.x86_64                             Fri Dec 14 21:02:00 2018

How reproducible:

Issue is intermittently seen in different environments

Steps to Reproduce:
Unknown currently

Actual results:

Seeing checksum error offsets reported by LVM

Expected results:

Expect PV to be able to be read, and restore/fix features to ignore checksum errors

Comment 16 Jonathan Earl Brassow 2019-08-28 15:06:47 UTC

We have a solution for this problem upstream and in RHEL8.  Unfortunately, it is too invasive to consider back porting to RHEL7 at this stage.  We will have to address cases as they come individually.  If this is a widespread and frequent problem (which it does not appear to be), perhaps there could be a workaround found.

Comment 17 Frode Sætre 2019-10-08 07:46:59 UTC

Any solution ?

Comment 18 aborniak 2019-10-09 07:21:28 UTC

I faced with same issue. 
In our case it has been fixed in following way: 
Boot from CentOS 6 and run "pvck" for affected physical volume. 
Then just run "vgcfgrestore".

Comment 19 Frode Sætre 2019-10-09 07:34:57 UTC

Thank you, we solved it the same way.

Comment 22 aborniak 2021-12-24 17:17:17 UTC

I was just faced with this issue again. 
Read my comment (2019-10-09 07:21:28 UTC) and fix it the same way as before.

Comment 23 Rahul 2021-12-29 13:21:23 UTC

I'm facing a same issue. Error as follows-
# pvs
  /dev/mapper/mpathd: Checksum error at offset 35328
  Couldn't read volume group metadata from /dev/mapper/mpathd.
  Metadata location on /dev/mapper/mpathd at 35328 has invalid summary for VG.
  Failed to read metadata summary from /dev/mapper/mpathd
  Failed to scan VG from /dev/mapper/mpathd
  /dev/mapper/mpathb: Checksum error at offset 35328
  Couldn't read volume group metadata from /dev/mapper/mpathb.
  Metadata location on /dev/mapper/mpathb at 35328 has invalid summary for VG.
  Failed to read metadata summary from /dev/mapper/mpathb
  Failed to scan VG from /dev/mapper/mpathb
  /dev/mapper/mpathc: Checksum error at offset 35328
  Couldn't read volume group metadata from /dev/mapper/mpathc.
  Metadata location on /dev/mapper/mpathc at 35328 has invalid summary for VG.
  Failed to read metadata summary from /dev/mapper/mpathc
  Failed to scan VG from /dev/mapper/mpathc

I removed the LV/VG/PV. While trying with "vgcfgrestore" getting error /etc/lvm/backup/nfsvg : no such file or directory.

I suspect the fix referenced above is https://gitlab.com/lvmteam/lvm2/-/commit/ba7ff96faff052c6145c71222ea5047a6bcee33b and surrounding commits, so this is likely a slightly different problem, despite its similar symptoms.

Comment 25 Zdenek Kabelac 2024-04-28 13:54:51 UTC

Please collect 1st. MiB of you device.

Attach  -vvvv trace from a pvcreate command.

And just try to use  'wipefs -a  /dev/loop0p1'  and retry your command.
(eventually you may try  'pvremove -ff' first)

And likely open a new BZ  (and refer this old closed one)
