I upgraded around December (upon the advice of some folks in the LVM
group) when my root fs when nuts and I had to try to repair it.

I do an initrd, to load lvm modules and register the lvm devices... so I
changed the linuxrc in the initrd to mount my root fs with the "conv"
option from within my Linuxrc:

	/bin/mount -o conv /dev/worley/newsys /mnt
	/bin/umount /dev/worley/newsys

It fed back the message:

	reiserfs: converting 3.5.x filesystem to the new format

Which made me hopeful that I'd found a solution.

But, I'm still not able to create large files:

	# dd if=/dev/zero of=./test.bigfile bs=1024 count=5242880
	dd: writing `./test.bigfile': File too large
	2097153+0 records in
	2097152+0 records out
	# ls -l ./test.bigfile
-rw-r--r--    1 root     root     2147483648 Jun 09 01:17 ./test.bigfile

So, I think the file system has been converted, but something is still
wrong in creating large files.  It's not a problem w/ dd or ulimit:

	# dd if=/dev/zero of=/dev/null bs=1024 count=5242880
	5242880+0 records in
	5242880+0 records out

	# ulimit -a
	core file size (blocks)     0
	data seg size (kbytes)      unlimited
	file size (blocks)          unlimited
	max locked memory (kbytes)  unlimited
	max memory size (kbytes)    unlimited
	open files                  1024
	pipe size (512 bytes)       8
	stack size (kbytes)         unlimited
	cpu time (seconds)          unlimited
	max user processes          8192
	virtual memory (kbytes)     unlimited

Thanks,
