Thank you so much, Gianluca! Yes, the source and target environments are the same version.
I'm not able to find /root/DisableFenceAtStartupInSec.txt anywhere, but maybe that's because at this point I've reverted to the original hosted_engine? Here is the output of the commands you sent: ------ [root@lnxvirt-engine ~]# engine-config -g DisableFenceAtStartupInSec Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false DisableFenceAtStartupInSec: 300 version: general [root@lnxvirt-engine ~]# set -euo pipefail && engine-config -g DisableFenceAtStartupInSec | cut -d' ' -f 2 Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false 300 engine=# select * from vdc_options where option_name='DisableFenceAtStartupInSec'; option_id | option_name | option_value | version | default_value -----------+----------------------------+--------------+---------+--------------- 45 | DisableFenceAtStartupInSec | 300 | general | 300 (1 row) ------ I also tried the following from the host I tried running the restore on. ------ [root@lnxvirt07 ~]# set -euo pipefail && echo "Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false DisableFenceAtStartupInSec: 300 version: general" | cut -d' ' -f 2 up 300 ------ Any additional questions or suggestions would be greatly appreciated.

We are trying to migrate the self-hosted engine to a new iSCSI storage domain using the existing hosts, following the documented procedure: - set the cluster into global maintenance mode - backup the engine using "engine-backup --scope=all --mode=backup --file=backup.bck --log=backuplog.log" - shutdown the engine - restore the engine using "hosted-engine --deploy --4 --restore-from-file=backup.bck" This almost works, but fails with the attached log file. Any help or suggestions would be greatly appreciated, including alternate procedures for migrating a self-hosted engine from one domain to another. Many thanks, Devin If I'm right, the starting error seems to be this one: 2023-10-14 11:06:16,529-0400 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:113 fatal: [local host -> 192.168.1.25]: FAILED! => {"changed": true, "cmd": "set -euo pipefail && engine-config -g DisableFenceAtStartupInSec | c ut -d' ' -f2 > /root/DisableFenceAtStartupInSec.txt", "delta": "0:00:01.495195", "end": "2023-10-14 11:06:16.184479", "msg": "no n-zero return code", "rc": 1, "start": "2023-10-14 11:06:14.689284", "stderr": "Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=f alse", "stderr_lines": ["Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false"], "stdout": "", "stdout_lines": []} As the return code is 1 ("rc": 1,) and determines the failure of the playbook, possibly the old environment doesn't have DisableFenceAtStartupInSec engine config property correctly set and/or the "cut" command fails... Or some other problem with that config parameter. Can you verify what it put into /root/DisableFenceAtStartupInSec.txt? I have only a 4.4.10 env at hand and on it: [root@ovengine01 ~]# engine-config -g DisableFenceAtStartupInSec Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false DisableFenceAtStartupInSec: 300 version: general [root@ovengine01 ~]# [root@ovengine01 ~]# set -euo pipefail && engine-config -g DisableFenceAtStartupInSec | cut -d' ' -f 2 Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false 300 [root@ovengine01 ~]# what is the output of this command on your old env: engine-config -g DisableFenceAtStartupInSec ? Are the source and target environments the same version? If you have access to your old env could you also run this query on engine database: select * from vdc_options where option_name='DisableFenceAtStartupInSec'; eg this way [root@ovengine01 ~]# su - postgres [postgres@ovengine01 ~]$ psql engine psql (12.9) Type "help" for help. engine=# select * from vdc_options where option_name='DisableFenceAtStartupInSec'; option_id | option_name | option_value | version | default_value -----------+----------------------------+--------------+---------+--------------- 40 | DisableFenceAtStartupInSec | 300 | general | 300 (1 row) engine=# Gianluca
