I've got a couple Fedora 15 boxes. One is a Primary/Master, the other is a Failover/Slave.
I'm looking for some advice on how image them so that they can be rebuilt within 3-4 hours.
My initial thought was to take weekly LV snapshots of / and /home (/home has a few things I can't lose). I would then re-install the OS, resize the LVs, dd the snapshots over / and /home, then apply the daily gzips and mysqldumps.
I ran through this process a few times. Worked sometimes, failed other times. The symptoms of the failures include startup failure of lm_sensors, iptables, and network. It would boot up to the GUI, but no Ethernet, and oddly enough, no auto-mounting of USB devices.
Don't know why it would sporadically fail like that, I run through the exact same commands each time.
Anyway....the failures have me thinking that this might not be the solution I'm looking for.
Any advice would be greatly appreciated.
