Given that, try checking and seeing if your old kernel also uses a
different fstab. If so, please see if somehow th eold kernel boot did
something like addressing EXT3s as EXT2s and then stripping the
journalling as a result. A Parted or Ranish run might tell you this
faster. Prefer fixing with Parted, however, as the Ranish that can
handle EXT3 right is still beta-- given that this appears to be a
production box, would back up if possible first also....
As for the multiple kernels, you might find some versions of running
software need some of the software loaded(called dependency h*** by
some)when the older kernels are used, would be careful with just syncing
unless you can do it when you expect at least a few hours of inactivity
and have a FULL backup in hand. An unhooked RAID or soft created backup
image\mirror snapped just before you experiment, with the image taken
offline, might be nice during the experimentation phase. Actually, if
were an option, would image to another box entirely, experiment and
annotate the changes there, then copy the process on a server.
