Eric,
I found your name and address on a thread about linux & xfs. I'm also
seeing the "kernel: __alloc_pages: 0-order allocation
failed." error on a 2.4.2-XFS system I just setup. We're comparing ext2,
reiserfs, and xfs with iozone. The xfs performance was looking great (50%
better on writes than ext2 or reiserfs) until the box fell over scrolling
these errors. It hangs the box and only a hard reset will suffice to
break out of it.
I seem to be able to reproduce the error by running iozone this way:
iozone -s 4000m
That's a big iozone run, but the systems all have 2gig memory so I've got
to go big to get out of linux cache and see meaningful numbers. Has there
been any progress with this bug? If you'd like, I can get you a temporary
acct. on the system where I'm testing.
-Galen
