Nice story, but as a bug report, this is mostly useless:
* After umount, did you run an e2fsck -f?
* Do you have a script(1) log of the whole session? (You'd probably
have this started as a last resort log then you started the
fsck'ing after the resize.)
* What exactly is "ext resizing utilities"? Did you save a copy of
it (incl. sources to find out about additionally applied patches?)
* These nonsensical names you refer to are the file's inode numbers,
in decimal. For mission-critical systems, it's wise to regularly
get inode listings with filenames. Did you compare those inode
numbers with your backups?
* Did you prepare an image-backup of your 1GB container beforehand?
Helps for easy recovery as well as error reproduction (esp.
because 1GB isn't all that hard to store on one CD when there's
plenty of free space, which can be made to compress very well.)
