Q: Update B2 with LVM over 3 HDDs?

Post by sm4vlm »

After years of good service I wanted to try wordpress om my bubba and realised that my B2 haven't been updated to latest releases... Actually realised (sadly) a whole bunch of things regarding Excito!

So I have looked at the update instructions, how to take my B2 from 2.0.xx to the latest USB image and I miss one piece of information.

The instruction state that external HD should be disconnected if you run a raid-set but in my case I have
two externel eSATA HDDs expanding the LVM to all three drives.

How do I manage my update?
----------------------------------------------
- Disconnect HDDs and boot from USB and connect after update?
- Boot with the USB-image with the external HDDs connected?

Updating past B2 version 2 requires a fresh install, which means it wipes everything. The way to go is to remove the disks, freshly install the B2 system, then update to the latest release (2.6.something) and then attach the two disks and expand the LVM to those disks.

Just a friendly warning, these operations (with three disks) has probably not been tested with 2.6 on B2, so I cannot 100% guarantee it works. It should, but if you have bad luck you might need to do some manual work to get the final pieces in place.

Good luck!
