lsdel hasn't worked since ext3 was introduced. Journaling requirements forced us to clear the i_blocks array, and this made lsdel non- operative. It's theoretically possible to change the kernel's unlink algorithm to avoid needing to zap the i_blocks array for most deleted inodes, but no one has

Yep, I just checked e2fsprogs_1.40.8-2ubuntu2.diff.gz, and sure enough, whoever packaged up e2fsprogs for Ubuntu simply snipped off the dietlibc-dev from the Build-deps line in the control file. Unfortunately there isn't a dietlibc-dev [!ubuntu] syntax for the rules file, so I guess Ubuntu package

The dietlibc-dev dependency can be safely removed. The rules files has a provision where if dietlibc is present, it is used to make e2fsck.static somewhat smaller in size --- from 1036k to 816k, for a savings of over 20%. But it is strictly optional, and perhaps a relic from the days when people

I very much doubt this was a problem with e2fsprogs, but rather with the RAID setup. If e2fsck was doing a full check after doing a journal replay, it's probably because the kernel had detected a filesystem consistency problem, and had set the "filesystem has an error" flag. The symptoms describe

Ah, OK, so the problem seems to be one UUID identification. OK, so this could be a blkid problem --- or the filesystem could just be corrupted enough that the UUID isn't identifying. We need to see the output of "sudo /sbin/blkid", and "ls -l /dev/disk/by-uuid", please. ** Changed in: e2fsprog

OK, so blkid is correctly identifying the filesystem. How about the output of this command: "sudo /sbin/fsck -C3 -R -A -N -V -a" The -N means to not actually do anything, and -V will print the commands that fsck would have executed. So you should see something like this # fsck -C3 -R -A -N -

The blkid library keeps old entries in /etc/blkid.tab even if the devices disappear, in the off-chance that it might be useful later. So the entries in /dev/sdc[12] are no big deal. The big indicator is the log from /proc/partitions; that indicates that /dev/sdb1 simply doesn't exist at the time
