Zfs and Oracle raw volumes

Question

This is the way I configured raw volumes to be used by Oracle 9:
# zpool create -f pool146gb c0t1d0
# zfs create -V 500mb pool146gb/system.dbf
# cd /dev/zvol/rdsk/pool146gb
# ls -l system.dbf
lrwxrwxrwx 1 root root 40 Oct 4 19:26 system.dbf -> ../../../../devices/pseudo/zfs@0:16c,raw
# chown oracle:oinstall ../../../../devices/pseudo/zfs@0:16c,raw
# zfs list -o name,volsize| grep system.dbf
pool146gb/system.dbf 500M
Resizing system.dbf to 600 MB
# zfs set volsize=600mb pool146gb/system.dbf
# zfs list -o name,volsize| grep system.dbf
pool146gb/system.dbf 600M
My question:
Is this a good approach for creating Oracle tablespaces in raw volumes?

Hi Marcis,
I tested raw device with Oracle but in AIX with Oracle 7.3 and
it worked perfectly. While I'm waiting for Oracle8i on Linux and
would test it with raw device, I don't think there would be too
much different.
