I finally succeeded making all working as expected!
What I did:
- compile corosync 2.3.0
- compile libqb 0.14.4
- compile dlm_4.0.1
- Compiled LVM 2.2.98
with your PREVIOUS patch (
I made a 2-node test cluster, both accessing a test iscsi target, all
daemons load fine.
Everything works as expected! Snapshotting is possible after -aey
--force explicit exclusive locking, lvresize works as well.
Previously, I tried your latest patch. I had a plethiora of errors,
starting with lvcreate failing:
#metadata/lv_manip.c:4137 Clearing start of logical volume "testvol2"
#device/dev-cache.c:599 /dev/san2/testvol2: stat failed: No such
file or directory
#metadata/lv_manip.c:4140 /dev/san2/testvol2: not found: device not
#metadata/lv_manip.c:4620 Aborting. Failed to wipe start of new LV.
I need to add -Z n to have it created. After that, most activations
failed, with error code 5. I went back to vanilla 2.2.98, all ok except
exclusive locking, applied the initial locking patch and voila! All done.
Thanks for your support!
