[Ocfs2-users] Fwd: Returned mail: see transcript for details

Luis,
  Let me understanfd your suggestion. Are you suggesting:
  $ORA_CRS_HOME -- without datavolume,nointr
  $ORACLE_HOME   -- without datavolume,nointr
  But place OCR, Voting Disks & future datafiles with datavolume,nointr
   
  Did I understand correctly?
  I have also gone back to OCFS2 1.2.5-6.
  Okay, if this is the suggestion -- I will surely try.
  Thanks.
  Anjan

  Anjan,

    The two installs I did with x86_64 were with ASM, with kernel versions that
today are very old, some years ago. Here I am using x86 (even as the hardware is
x86_64 capable) due to a managment decision not to go to x86_64.

     Anyone else on the list?

     About the mount points, the CRS home is a ORACLE_HOME, so you shouldnt
mount it with datavolume. If you want to keep the CRS ORACLE_HOME and the RDBMS
ORACLE_HOME each on one filesystem you should have at least a third partition
for the cluster registry, voting disks and datafiles, mounted with the
datavolume option, and mount those two without it.

    If you need to get this working fast, I think you should try a older OCFS2
module version. If not keep working with Mark and the other Oracle people here
on the list as they can diagnose these errors and get it fixed.

    What is the firewire disk you are using?

Regards,
Luis

As far as I know, it's not recommended to mount ORACLE_HOME with
datavolume,nointr but that's not the case with CRS. So, I have different
mount options for ORA_CRS_HOME (home/oracle/ocrvotcrs) & ORACLE_HOME
(home/oracle/orasys). If I am wrong, please correct me. Also, I don't have
any datafile yet because I don't have the basic thing -- Oracle binary under
ORACLE_HOME. Once I have that, I will have datafiles & mount will contain
datavolume,nointr.
Do you know anybody has successfully implemented OCFS2 1.2.7-1 on Red Hat4.5
(kernel 2.6.9-55.EL) under 86_64 architecture?
What exactly you have?
Thanks for your continuous effort to help me.
I hope somebody else will also start joining this discussion & help me.
I am really stuck -- can't advance at all -- need help desperately.

Anjan,

   Well it is only a sugestion.

   About those mount options, perhaps the Oracle people can give you a feedback
on that also. But I noticed that you have two mount points, and seems to be
installing CRS binaries on one, and RDBMS binaries on the other. So, where are
datafiles?

    You shouldnt be installing the CRS home on /home/oracle/ocrvotcrs as it has
the datavolume option. It is not clear if you are trying this.

    The filesystems where you have binaries should not have the datavolume
option, and the filesystems with datafiles, voting disks and the cluster
registry need to have the datavolume option.

Regards,
Luis

  Thanks to both of you for trying to help me.
  I have alreaddy communicated to Luis that I have to have OCFS2 because my
software needs Clustering technology that is absent in EXT3. Moreover, both CRS
& RDBMS homes should also be on shared/clustered system -- so, OCFS2 is the
only choice.
  If you can help me to understand/resolve this issue, I will really appreciate
that.
  Please note that my FireWire shared drive works perfectly when I use RAW but
as soon as I am trying to use OCFS2, all the problems started.
  Thanks.

  Luis,
Thanks for helping here. I have one comment regarding moving the
shared home to ext3. If Anjan's setup is having issues like this, moving his
oracle home to a local disk would only hide problems which take longer to
reproduce for the crs and data files partitions. What needs to happen is
that the root cause of his problems is discovered and fixed.

Keep in mind, I'm not saying someone couldn't use ext3 for their oracle
install - it's an excellent choice for running a non-shared oracle home.
It's just not a good shared disk diagnostic tool ;)

Once again, thanks for stepping up and lending a hand.
