Hi,

I'm using Reiser4 for my filesystems on disk (/dev/sda) , and it
works just fine. Recently I bought a second disk (/dev/sdb) for
RAID-1 mirroring. With mdadm I created a degraded raid-1 array  on
/dev/md/0, devices missing,/dev/sdb1. After that I created a Reiser4
filesystem on /dev/md/0 and mounted it at /mnt. Then I copied the
data from /dev/sda1 to /mnt.


would it work better with "no_write_barrier" mount option?

It would indeed. What's the purpose of this option?

Kind Regards,

Arend
