Re: clustered lvm volume activation

Hello Timm,

I had exactly the same problem a few weeks ago. It pissed me off quite a bit, but I made myself a reason.

My workaround is not to define the volume pool anymore. The domains are able to use any volume anyway, even when not part of any pool.

I use custom hooks to activate and deactivate LVs.

Hope that helps,

Guy

dear all,

i have a problem with clustered lvm storage and the "logical" storage
driver, perhaps someone has a suggestion.

i have a clustered lvm (lvmlockd, not clvm) with 4 hosts running.

when i start the storage on a host it activates all volumes in the whole
volume group. then i cannot start the storage on other hosts because all
volumes are already activated on one host.

if i then deactivate all volumes in the started pool i can start the
pool on other hosts. but then i have to manually activate the volume if
i want to start the domain.

it would be great if the logical pool driver would only activate the
volume of a domain at domain start and not on pool start.

does anybody have a workaround for this or any suggestions for me? do
you think i should open an issue on it?

Regards,
Timm
