Hi everybody,
I have the same problem when I use vgs command, so I used vgs -vvv command and it was slow when the output command showed me this "Archiving volume group "vgoracle" metadata (seqno 3)", I have many vgs with this status, Archiving volume group xxx, Is it normal? What can I do to solve this?
Thanks
Marcos Dutra

Thanks Alasdair,
Turns out I got a great suggestion to wrap this up in strace via the
IRC channel. Turns out I'm scanning on some devices that are being
plugged in and out of the system and the failure is due to the fact
that the raw device gets ripped out from under the vgscan.
Going to try limiting the devices I interact with via lvm.conf, I
think that will address the issue.
Thanks,
John
