I was coping an ISO image via NFS to a directory on an ext3 partition
(dev/hdc2) and the computer locked up as soon as I hit the enter key. I've
had problems before with ext3 and nfs (see FYI below), but this time it was
on a different hard drive (first time was /dev/hda) and this time I got an
oops along with a machine lockup. After hitting the reset button (machine was
dead) I ended up having to delete a mysql index file because fsck couldn't
repair it.
LABEL=/storage /opt ext3 defaults 1 2
FYI - I ran into some reproducible problems before with ext3 and possibly
NFS. I had a 1365344k oracle database export gzipped down to 263688k and then
made into an ISO image. I'd copy the file from the file server
(2.4.3-SGI_XFS_1.0.1) via NFS , mount the ISO image, and burn it to CD
without any errors being reported. When I'd try gunzip the file from CD, I'd
get CRC errors. I then tried mounting the ISO image and running gunzip and
I'd get the same CRC errors.
I went back to the file server, mounted the ISO image, and had no problem
gunzipping it. I then tried coping the same file again via NFS but gave it a
different name to copy to. Running both diff and cmp told me the files were
different and both couldn't be gunzipped from mounted ISO images.
I could also copy this file to a new file name in the same directory (cp
db.iso timma.iso) and when I ran both diff and cmp, they reported differences
between the two files. I then tried using SCP to copy the file over and I had
no problems. All this was repeatable. I upgraded kernels from RedHat 7.3
stock 2.4.18-3 to vanilla 2.4.19 and problem seemed to go away.
I'd be happy to provide anymore information!
