You should be able to check the boot logs to see if the file systems were mounted cleanly or if they had to have their journals checked.
I see this in messages: Aug 14 12:36:05 xen kernel: EXT3-fs: INFO: recovery required on readonly filesystem. Aug 14 12:36:05 xen kernel: EXT3-fs: write access will be enabled during recovery. Aug 14 12:36:05 xen kernel: EXT3-fs: recovery complete. Aug 14 12:36:05 xen kernel: EXT3-fs: mounted filesystem with ordered data mode.

Doesn't look good, but I wish I could get a definitive answer...
Thanks! jlc
