New location for drbd scripts

This document (000020749) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise High Availbility Extension 15 SP4

Situation

When upgrading from SLES15 SP0 , SLES15 SP1 , SLES15 SP2 or SLES15 SP3 to SLES15 SP4 version the drbd resource will stop handling Resource-Level Fencing with STONITH .

The drbd resource is defined. From supportconfig ha.txt:
# /usr/sbin/crm configure show
...
primitive drbd_demo01 ocf:linbit:drbd \
   params drbd_resource=demo01 \
   op monitor interval=15 role=Master \
   op monitor interval=30 role=Slave
primitive stonith-sbd stonith:external/sbd \
   params pcmk_delay_max=30s

From supportconfig drbd.txt, we see the paths used for the fencing scripts:
# /sbin/drbdadm dump
...
# defined at /etc/drbd.d/demo01.res:1
resource demo01 {
...
handlers {
fence-peer /lib/drbd/crm-fence-peer.9.sh;
after-resync-target /lib/drbd/crm-unfence-peer.9.sh;
}
}

Resolution

Update to latest drbd-utils version .
Fixed version is 9.19.0-150400.2.3.1 and later.

Cause

The SUSE Linux Enterprise High Availbility Extension 15 SP4 was released with drbd-utils version 9.19.0-150400.1.7 and the patch to conform to the location of the crm-fence-peer.9.sh , crm-fence-peer.sh, crm-unfence-peer.9.sh and crm-unfence-peer.sh scripts to /usr/lib/drbd/ got dropped by chance. The path /lib/drbd/ should have been changed to /usr/lib/drbd/.
