Re: clvmd does not create vgs

[שלום קלמר <sklemer@xxxxxxxxx>]

Hi.

try add lvm to this volume.

I think that the locking is working on lvs & not on the VGs.  After creating the lvs, I think

you should see both vgs & lvs.

Shalom.

Hi,

thanks for your reply. pvscan finds the new created pv but vgscan can't find any new volume group on node2. Locking type is set to 3 on both nodes. When running in debug mode with "clvmd -d" I get this messages

have you tried to pvscan/vgscan on node2 after creation on node1 ?
