How long does it take to fsck an 80GB hard drive?

I am in the middle of manually fsck-ing my dual 80GB MK-IIA, and need to know if it is going to be done before I get off work.

Anyone?

Moved from Off Topic. Because it's not.

Apparently there is no firm answer to this. It probably depends on how many files you have on each drive.

The first drive took about an hour to fsck. The second one took 20 minutes.

It is entirely dependent on how fsck'd up your drives are.

Well, it certainly depends on how full they are. A full 80GB drive can take up to about an hour (from memory). This is improved if the drive is not completely full, if you have more memory / swap enabled and if there are no errors.

Too long, unless you formatted with the spare superblock according to Roger's site.

I think it's between 10 and 20 minutes.

Also, since you've a dual drive, you should be able to run the fsck on each drive in parallel. Make sure fsck pass numbers are set up in /etc/fstab ( / = 1, and everything else = 2) and add a "-A" to your fsck, "fsck -faAy" fsck is smart enough to not check multiple partitions on the same drive simultaneously.

Huh? My 3/4 full 60GB takes longer than that and I know it is good.

Don't know what to say. Did you format with the sparse superblock?

Yeah, but your filesystem was unmounted cleanly. I don't know about Doug's or what situation Trevor was referring to.

I don't know about Doug's or what situation Trevor was referring to.

My situation was caused by an emplode failure during re-synch (lost network connection) so it got corrupted while it was in RW mode.

The manual fsck (on each drive) and manual database rebuild fixed everything. SInce the first drive took about an hour, and the second one only 20 minutes, I suspect that both Bitt and Jim (Hogan) are correct -- the first disk is the primary and is nearly full; the second was added later and is perhaps 25% full. (just guessing -- since the first one was nearly full when I added the second, and I haven't deleted anything) Probably the corruption was on the first disk.
