Ferenc, regarding the flag use_lvmetad in /usr/lib/ocf/resource.d/heartbeat/LVM I read: "#lvmetad is a daemon that caches lvm metadata to improve the # performance of LVM commands. This daemon should never be used when # volume groups exist that are being managed by the

Re: [ClusterLabs] HALVM problem with 2 nodes cluster

Hi Bliu, thank you. I agree with you for use_lvmetad = 0 (setting it = 1 in a clustered environment is an error) but I think I have to set locking_type = 3 only if I use clvm In my case, I'm trying to use LVM so I think that locking_type = 1 is ok. What do you think about? Furthermore, I have an

Hi, I'm trying to realize a cluster with 2 nodes that manages a volume group. Basically I have a san connected to both nodes that exposes 1 lun. So both nodes have a disk /dev/sdb. From one node I did: fdisk /dev/sdb <- Create a partition with type = 8e (LVM) pvcreate /dev/sdb1 vgcreate myvg
