Thank you David !
Would you consider the use of lvmlockd + sanlock as "production ready" ?
My goal here is to replace an existing cluster of 5 nodes using clvmd + dlm
+ corosync to access a shared VG of 6 TB containing around 300 LVs.
The current solution is working fine but I find using dlm + corosync "just"
for locking a bit overkill.
