OCFS Performance vs. Raw
We are seeing some performance issues runnig on 64-bit
Linux. Running against a raw partition we can get
100MB/s write speed when creating a datafile. Using
OCFS we get 30-40MB/s and at times it is so slow it is
hard to measure.
Anyone else see these issues? We are running the
latest versions of both Oracle and OCFS. I've opened
a ticket with Oracle but am interested in other's

Mode context extremely poor performance.
Hi all,
I curently have a big problem. One request (listed above) using context
take up to 1000 more time than the on RAW or ext2 database. I have ran
this request on a single IA32 machine with Redhat and dbf on ext2. The
average reponse time is less than a sec. The same request on RAC 4 nodes
cluster on RAW take the same average time. On ext2 idem. But on OCFS it
took up to 15 sec randomly

OCFS Database too slow
Hi All,
we are using Red Hat 2.1 Kernel e38 along with MSA 1000.
ocfs version being used is
$ rpm -qa | grep ocfs
ocfs-tools-1.0.10-1
ocfs-2.4.9-e-enterprise-1.0.12-1
ocfs-support-1.0.10-1
Database Version is 9.2.0.5
However we find that the performance of the database on OCFS is too slow. even a select count(1) from all_tables takes like a while to complete.
We initially assumed RAC is

OCFS and split mirror backups
Are there any known issues with using a split mirror
of the OCFS partitions for backups?
One option we are looking at is as follows:
1. Put tablespace in backup mode.
2. Split the mirror at the SAN level.
3. end tablespace backup mode.
4. mount the OCFS mirror under a different mount
point.
5. backup the files on the OCFS mirror using RMAN.
The question is how feasibile it is for step #4 to
