E2fsck uses the blkid library to map LABEL= and UUID= references to device names.
What about if th blkid library was to report some sort of 'duplicate label name' error, when it maps the devices to label names?
That would be a great help.
One thing that you might do for devices that are always present (which generally means you're not changing them in your /etc/fstab often) is to use a UUID= reference instead. They are definitely less convenient than labels, but they are also much less likely to cause confusion by having duplicately labelled file systems. Granted, no one wants to *type* "mount UUID=9e132c06-1fd0-4bbd-ad06-5995a8f45b26"; they'd much rather type "mount LABEL=websites". But if the only place the a UUID=... specification shows up is in /etc/fstab, it might be worth it.
Can I set the UUID value, with some descriptive text,(something like a long label name), or is the UUID only system generated?
Then you can just zap the label on file systems that you only plan to reference via UUID, and then that reduces the chances for confusion in the future. Best regards,PS Are there any PDF docs that would give me an overview of the ext3 FS, and how it works?Try the list of Articles and Publications here: https://ext4.wiki.kernel.org/index.php/Publications
I'm reading up on that stuff now. The first link in the list is interesting :)I think the reason the USB has SO MANY errors on the FS is because I possibly unplugged it, before umounting it!
I understand that the umount command flushes any disk I/O buffers back to the drive?
