Re: [linux-lvm] pvs complains of missing PVs that are not missing



Dne 23.10.2013 18:43, Joe Harvell napsal(a):
Hi Joe,

I am having similar issues in that I have a LVM2 raid1 mirror between a
local disk and a iSCSI disk and once I remove the iSCSI disk and add it
back, the mirror stays broken. I traced the cause of that to be LVM2 still
complains about a PV missing even though the same PV has been added back.

I wonder if you have resolved your issue and what did you do.
Thanks a lot.
Shi

Shi,

This is not yet resolved.  I'm still waiting for Peter Rajnoha to follow up
after I provided him the information he requested.  He said he might be able
to look at it more closely later this week. In the mean time, I work around
this issue by activating the VG with --partial.  I can access my data, but I
can't make any LVM config changes.



If the missing PV is reattached to your system - you need to

vgextend --restoremissing   /dev/path_to_PV


Since once the PV is detected as missing - metadata are update on present PVs,
and the missing PV is marked as MISSING.
When such PV reappear - you need to run the command to re-synchronize metadata.
