Hi,
I've run a couple of tests with the different data logging modes
writeback, ordered and journal.
All data logging modes were perfectly stable, a kernel compile and a
bonnie benchmark on /dev/md0 mounted on / did not have any negative impact
on the filesystem. reiserfsck said that it was clean.
Testparameters:
===============
KERNEL=2.4.21-rc1 + Chris Masons data logging + quota patches (nr's: 02 to 10)
TEST PARTITITION SIZE=10GByte on LVM
PROCESSOR=AMD Athlon XP 2000+
RAM=512MB DDR 266
HARDDISK=Seagate Baracuda IV, 60GB
TEST WRITE_BUFFER=4096
TEST FSTYPE=reiserfs
TEST REP_COUNTER=3
TEST GAMMA=0.0
TEST NPROC=3
TEST SYNC=off
SER FILE_SIZE=4096
SER BYTES=250000000
reiser writeback reiser ordered reiser journal

Thanks for the measurements. Try it with writing a single large file
also....
