Odd issue with df command

protocol · 04-03-2010, 07:22 AM

Hello all.

My "df" command provides this:

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 436G 1.0G 413G 1% /
/dev/sdc1 452G 199M 428G 1% /dsk/two
/dev/sdb1 452G 199M 428G 1% /dsk/one

I notice that my /dev/sdc disk appears before /dev/sdb, which i consider odd because i can clearly remember a time that this was not so. Does it mean anything? Should i do something?

I don't think this is something to worry about, but try "fdisk -l" also.

No, and no.

I believe df shows them in the order they're mounted in. If you want them the other way around, edit your /etc/fstab and put one before two.

Perhaps that's distribution dependent, but on my Fedora 12 system, df lists them in the same order that mount lists them, but that's not the order in which fstab lists them. (I suspect that the mount order is the order in which udev processed the entries from fstab, which is not quite the same thing as the fstab order.)

Good point. That's quite possible, depending on how clever your distro tries to be while processing mounts.
