Hi, I'm running ovirt Version 4.5.3.2-1.el8 with 1 + 3 nodes setup. Currently i'm encountering this issue of ovirt-engine portal certificate which has already expired. "PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed " I'm aware of the solution by running "engine-setup --offline" to renew the cert. (https://yaohuablog.com/zh/ovirt-engine-upgrade-web-certificate) However my host machine has this problem with the psql command issue whenever i run the engine-backup. [root@server1~]# engine-backup --mode=backup Start of engine-backup with mode 'backup' scope: all archive file: /var/lib/ovirt-engine-backup/ovirt-engine-backup-20240103163047.backup log file: /var/log/ovirt-engine-backup/ovirt-engine-backup-20240103163047.log psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) Backing up: psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) psql: /lib64/libpq.so.5: no version information available (required by psql) Notifying engine - Files - Engine database 'engine' Notifying engine FATAL: Database engine backup failed [root@server1~]# dnf module list postgresql Last metadata expiration check: 1:55:29 ago on Wed 03 Jan 2024 02:38:30 PM +08.

Should i fix the psql error first ? If i just want to renew my certificate , will the psql error cause me to fail to renew the cert in the "engine-setup --offline" command ? 2. What if after the "engine-setup --offline" failed to renew will my running VM be affected and down ? will there be any recovery method later ? will the reinstallation work on stand-alone machine ?
