Description Jiri Belka 2024-04-08 08:34:01 UTC

CREATING AN LVM-ACTIVATE RESOURCE:

https://documentation.suse.com/sle-ha/15-SP5/html/SLE-HA-all/cha-ha-clvm.html#pro-ha-clvm-rsc-lvm-activate

There is not "glue" between lvmlockd and the actual VG, thus VG might be (and often is) activated before lvmlockd is ready and thus it would fail...

An example (from a customer case):

group base-group dlm clvmd
group group_GSXP Cluster_IP_gasxp VG_gasxp01vg_new FS_gasxp01lv01_new FS_gasxp01lv02_new FS_gasxp01lv03_new FS_gasxp01lv04_new FS_gasxp01lv05_new FS_gasxp01lv06_new FS_gasxp01lv07_new FS_gasxp01lv09_new FS_gasxp01lv10_new FS_gasxp01lv11_new FS_gasxp01lv12_new FS_gasxp01lv13_new FS_gasxp01lv14_new FS_gasxp01lv15_new rwe_GASXP \
        meta target-role=Started

clone base-clone base-group \
        meta interleave=true target-role=Started

# to be added: glue between clvmd and group using FS on shared VG
colocation col-group_GSXP-with-base-clone inf: group_GSXP base-clone
order ord-base-clone-before-group_GSXP Mandatory: base-clone group_GSXP

Could you improve the docs please? 12-SP5 has same issue for clvmd.

Here's the PR: https://github.com/SUSE/doc-sleha/pull/373

Jiri, let me know if this solves the problem :) 

Yan, could you please look too? Does this make sense?

LGTM. only a nitpicking there.

I'm looping in Roger to take a look as well.
