Comment 14 for bug 728088

I have upgraded my Ubuntu Desktop with iSCSI root from Maverick to Natty yesterday (it was installed originally as Karmic and upgraded to each new release with no problems regarding iSCSI). It started failing exactly like in this bug description and after a short trial and error trying to solve it, my root file system (XFS) was damaged beyond repair. If I indeed hit the same problem, then it's caused (also) by something else than debian-installer, as my upgrade had nothing to do with it.
By the way, it seems like a good idea for such upgrades to take a snapshot of iSCSI volume before upgrading...
