As a guess, the partition label is screwed up. 
The OS uses this 
statement in fstab to attempt the mount at boot:

LABEL=/home/cj/archive  /home/cj/archive  ext3    defaults     1 2


and, somehow, the label gets mapped to /dev/sdb1.  But this is what works:

mount -t ext2 -w /dev/sdc1 /home/cj/archive


Definitely not the same.  A quick fix is to just change fstab to use the 
device definition that works:

/dev/sdc1	/home/cj/archive  ext3    defaults     1 2


I'm guessing there is a user program such as diskdruid to change the 
partition label.  Unfortunately, I don't know what it is.  Perhaps 
someone else on the list can enlighten both of us.

Cheers,
Dave

This is supposedly what should work, if I'm reading all the man pages 
correctly - that's the entry that had been created automatically by whatever 
process does that

Here's where the mystery begins - that command *does* work, but, it's 
incorrect! The file system is ext3 not ext2 - I know they're related, but, I 
just experimented, and I can mount manually using that command with either 
ext2 OR ext3???

I've tried this, but, it still doesn't work -

tune2fs is supposed to be able to do this, but I couldn't grasp the 
explanation of how it works well enough to attempt it when I tried in 
somewhat of a hurry a couple of weeks ago

apropos label

e2label              (8)  - Change the label on an ext2/ext3 filesystem
findfs               (8)  - Find a filesystem by label or UUID
mlabel               (1)  - make an MSDOS volume label
ppmlabel             (1)  - add text to a PPM image
vol_id               (8)  - probe filesystem type and read label and uuid

man e2label

SYNOPSIS
       e2label device [ new-label ]

DESCRIPTION
       e2label  will  display  or  change  the  filesystem  label  on the ext2
       filesystem located on device.

       If the optional argument new-label is not present, e2label will  simply
       display the current filesystem label.




"apropos" is to Linux, what "Google" is to the WWW.
