Hi, I am confused about the usage of clvmd. On a blank 80 GB disk I created a logical volume using the following commands (after the cluster was started with "ccsd; cman_tool join; fence_tool join" on all nodes): # overwrite a former partition table: dd if=/dev/zero of=/dev/hdb bs=512 count=1 # initialize the physical volume: pvcreate /dev/hdb # create a volume group "vg301": vgcreate vg301 /dev/hdb # create a 40 GB logical volume "lvol0" inside vg301: lvcreate -L 40G vg301 # start clvmd clvmd # mark the volume group as "clustered" (there are no other vg's): vgchange -cy # activate the volume group with/without cluster locking vgchange -aey ...or... vgchange -aly vgchange prints a notice if on some other node of the cluster clvmd is not running and activates the logical volume. Is this enough to use "vg301" or "vg301/lvol0" on the other nodes? If yes, how do I access vg301 from another (than the local) node? vgscan, executed on the other nodes, does not report anything. Distributing the local vg301/lvol0 (with GFS on it) with GNBD 'nearly' worked: At some point, the I/O was blocked on nodes accessing a specific directory. gfs_mkfs -p lock_dlm -t Isabella:lvol0_301 -j 4 /dev/vg301/lvol0 gnbd_export -v -e exp301_0 -d /dev/vg301/lvol0 Is there any information / documentation about clvmd? The lvm-HOWTO does not cover this topic :-( Many thanks! -- Michael Weitzel -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
