Patroni and ETCD: Upgrade from PostgreSQL 10 to PostgreSQL 14 Begin by installing PostgreSQL 14.  In this case we're installing all PostgreSQL 14 packages. yum install postgresql14* Check version after installation: [root@psql04 ~]# /usr/pgsql-14/bin/psql –version psql (PostgreSQL) 14.5 [root@psql04 ~]# [root@psql04 ~]# grep -Ei bin_dir /etc/patroni.yml     bin_dir: /usr/pgsql-14/bin [root@psql04 ~]#

Restore VM's from snapshot.  Yes, this is a new attempt at restoring some FreeIPA hosts that have been, ahem, neglected slightly to the point where things expired and don't work.  A few unexpected reboots and FS corruption didn't help the matter either.  Regardless, the recovery will in many ways show off the restoration capabilities of.FreeIPA which […]

After regenerating the initramfs using dracut -f, we end up seeing the following, rather disappointing message: r8169 0000:09:00.0: no dedicated PHY driver found for PHY ID 0x001cc912, maybe realtek.ko needs to be added to initramfs?
