Title: Upgrading from b5 to b9
Post by: jdc0730 on December 28, 2005, 07:59:19 PM

I am currently running b5 on my server.  The OS is on 2 80g hard drives connected to a 3ware card running RAID1.  There is also a 1.5 TB RAID5 array on the system connected to another 3ware card.

When I start the upgrade using the CD from b5 to b9, I get an ominous "Converting to RAID" message and my big array starts to get hammered.  In a panic I killed the process.  Everything appears to still be fine.  What is going on here?  That drive holds all my photos and FLAC files (which represents months of ripping).   I am paranoid that I am going to lose data.  Can anyone shed any light or point me in the right direction?

Thanks!
Jeff

sounds like the o/s is trying to install using all the drives in some form of RAID.  I would disconnect the RAID 5 array, do the install, then reconnect the array.  I mean physically disconnect it.  If you don't, the o/s will use all the drives.

Just my opinion.

Will this do an upgrade or an fresh install?

"Converting to RAID" purely does the following:
- Change the partition table id from Linux to Linux raid autodetect
- Shrink the filesystem to allow a RAID metablock to be added
- Fsck the filesystem at the new size

If the RAID5 array appears as a single disk, it should be converted without issue. You should not lose data. However, we haven't tested such a setup.

If you take Marco's advice and disconnect the RAID5 device, you will be able to perform an upgrade (or fresh install if you choose that) on the main disk and re-add the RAID5 later.
