Hi David,
I's afraid the statement below in description section of lvmlockd manpage:
"
· prevent concurrent activation of logical volumes
"
is easy for normal user to mistake it as: wow, lvmlockd doesn't support
active-active
LV on multiple nodes?
What I interpret from it is:
with clvmd, 'vgchange/lvchange -ay' activates the LV on every node in a
shot.
But with lvmlockd, one needs to perform:
- start the lockspace
vgchange --lockstart vg1
- vgchange -ay vg1
The LVs in vg1 will only be activated on this node.
Regards,
Eric
