and then I ran fsck:

and ran it again, just to check...

There was, apparently, a power failure, today. My wife booted up the System0, but it didn't boot properly. There was some text on the screen with some error messages about mounting filesystems. I should've paid closer attention to those messages. Instead, I went straight to trying to repair the filesystems. I booted from live DVD for mythbuntu
ubuntu@ubuntu:~$ sudo parted -l Model: ATA SAMSUNG SP0822N (scsi) Disk /dev/sda: 80.1GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 1287MB 1287MB primary ext2 boot 2 1287MB 10.3GB 9052MB primary linux-swap(v1) 3 10.3GB 26.5GB 16.1GB primary ext3 4 26.5GB 47.9GB 21.5GB primary ext3 Model: ATA Hitachi HDT72101 (scsi) Disk /dev/sdb: 1000GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 1000GB 1000GB jfs Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 vhas been opened read-only. vError: /dev/sr0: unrecognised disk label
then I checked for errors
ubuntu@ubuntu:~$ sudo fsck.jfs -n /dev/sdb1 fsck.jfs version 1.1.12, 24-Aug-2007 processing started: 5/13/2011 2.43.16 The current device is: /dev/sdb1 Block size in bytes: 4096 Filesystem size in blocks: 244190429 **Phase 1 - Check Blocks, Files/Directories, and Directory Entries **Phase 2 - Count links **Phase 3 - Duplicate Block Rescan and Directory Connectedness **Phase 4 - Report Problems **Phase 5 - Check Connectivity **Phase 6 - Perform Approved Corrections **Phase 7 - Verify File/Directory Allocation Maps Errors detected in the Fileset File/Directory Allocation Map control information.

File system checked READ ONLY. Filesystem is dirty. Filesystem is dirty but is marked clean. In its present state, the results of accessing /dev/sdb1 (except by this utility) are undefined.
then I attempted repair
ubuntu@ubuntu:~$ time sudo fsck.jfs -f /dev/sdb1 fsck.jfs version 1.1.12, 24-Aug-2007 processing started: 5/13/2011 2.45.33 The current device is: /dev/sdb1 Block size in bytes: 4096 Filesystem size in blocks: 244190429 **Phase 0 - Replay Journal Log **Phase 1 - Check Blocks, Files/Directories, and Directory Entries **Phase 2 - Count links **Phase 3 - Duplicate Block Rescan and Directory Connectedness **Phase 4 - Report Problems **Phase 5 - Check Connectivity **Phase 6 - Perform Approved Corrections **Phase 7 - Rebuild File/Directory Allocation Maps **Phase 8 - Rebuild Disk Allocation Maps 976761716 kilobytes total disk space. 146089 kilobytes in 66698 directories. 953111998 kilobytes in 413620 user files. 20 kilobytes in extended attributes 506995 kilobytes reserved for system use. 23288792 kilobytes are available for use.

oh, yeah - that's the swap partititon. oops....

So both my /storage drive and my boot partition needed repair...
