Hello -
I'm having a problem with XFS and/or the 2.4.6 kernel. Since
2.4.6+XFS is not an official release, I'm guessing the first
thing would be to use 2.4.5-xfs-1.0.1... unless this is a known
problem which 2.4.5 might have as well? In any case, I'd like
your advice on which version to use, to try and recreate this
and get more debugging information. (I know what I've included
is probably not enough.)
Can you try a CVS kernel?
The symptoms are files which were written *minutes* ago retain
the right size, but seem to develop blocks full of zero bytes.
I think this mostly happens when memory runs very low, but I'm
not sure. I'm running an SMP kernel, with no swap space, and I'm
writing files to "tmpfs" at the same time. (With the UP kernel,
I've noticed a different, but possibly related problem when
memory runs low where bdflush gets stuck taking 100% of the CPU.)
What compiler did you use? Egcs 1.1.2 is the recommended compiler for
production use.
Usually, there are no errors from the kernel while this is
happening, but eventually I got these:
kernel BUG at ll_rw_blk.c:700!
invalid operand: 0000
...
And "free" showed:
total used free shared buffers cached
Mem: 254120 243684 10436 0 51688 215380
-/+ buffers/cache: -23384 277504
Swap: 0 0 0
Why run without swap?
Cheers

Every program has two purposes one for which
it was written and another for which it wasn't
I use the last kind.
