I know this isn't entirely OCFS related, but out of curiosity, but what experience have you had running RAC on RedHat or SuSE? I know Oracle supports both, but is one a better choice than the other? Seems to me like Oracle has been working more with RedHat. Does anyone know what Oracle mostly uses internally? What distro do you guys develop on? Would there be any drawbacks for choosing to

Hi, I am trying to install Oracle 9i RAC on SLES 8 SP3 with a shared firewire disk. I am using the following OCFS: OCFS Release 1.0.11-1 for suse sp3 2.4.21-138 smp kernel ocfs-2.4.21-138-smp-1.0.11-1.i586.rpm ocfs-tools-1.0.10-1.i386.rpm ocfs-support-1.0.10-1.i386.rpm 1/ I have configured OCFS and a shared file system /opt/oracle/oradata 2/ I have created a raw device for use as quorum

How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id:

A couple years ago, we moved to Oracle RAC on Linux using ocfs that is SAN attached to an EMC CLARiiON. At the time, there was a reason that we did NOT use EMC's Powerpath (I just can't recall what that reason was). What I'd like to know is if there are any issues with introducing Powerpath now. * RHEL 2.1 AS * 2.4.9-e.38enterprise * ocfs-2.4.9-e-enterprise-1.0.13-1 * EMC

Hi there, have a strange behavior if i?ll create a zfs pool at an EMC PowerPath pseudo device. I can create a pool on emcpower0a but not on emcpower2a zpool core dumps with invalid argument .... ???? Thats my second maschine with powerpath and zfs the first one works fine, even zfs/powerpath and failover ... Is there anybody who has the same failure and a solution ? :) Greets Dominik

On some machines running PowerPath, there''s sometimes issues after an update/upgrade of the PowerPath software. Sometimes the pseudo devices get remapped and change names. ZFS appears to handle it OK, however sometimes it then references half native device names and half the emcpower pseudo device names. So the SA can easily be confused. Is there a way to tell ZFS which device names

Dear All, Can somebody help me on the following issue: When I mount the SCSI device on storage with ext3 filesystem & perform cp in loop, it becomes readonly. The steps to reproduce the issue are: 1)Create a ext3 file system on HDLM device mkfs ?t ext3 /dev/sdn 2)Mount the device Mount /dev/sddlmaa /home/<dir. name> 3)Execute cp ?f command in a loop on mounted device.

Hi, We had received a new EMC storage (Clariion CX4) and the EMC analist has told us that CentOS aren't on their support list, but RHEL are :) Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage, preferably using the EMC Powerpath software, and can talk about you experience? Or I will need to buy some REHL licenses ? I'll put my hands on it only next

I used this command to create volume label on OCFS: mkfs.ocfs -F -b 128 -L data13 -m /oradata/data13 -u oracle -g dba -p 0775 /dev/emcpowerp1 emcpowerp is composed of /dev/sdad and /dev/sdk. It seems the above command created the same labels for /dev/emcpowerp1, /dev/sdad1 and /dev/sdk1. But when I tried to mount this ocfs filesystem by label, it gave me the following error. # mount -L data13

We are running Linux AS 2.1 .27 enterprise on an EMC CX400 SAN with ocfs version enterprise 1.0.9-12. After formatting the partitions the response from the filesystem is very slow during either read or writes. Even worse, while we can create a directory, we are unable to delete the directory after it has been created. Every time any directory is attempted to be removed with rmdir we get a

Hello, It is not total off-topic since almost all connected servers will be RHEL and CentOS. :) We are considering to purchase new storage system. The most probably we will be choosing between HP (EVA6000), EMC (CX3-20C) and Hitachi (similar model). iSCSI connection is also required. What are your experienced with listed systems? What to avoid? What ot expect? Now I just know

Doesn't instill confidence. Well wonder no more!! Simply look it up in the man pages. It is documented after all!! Hummm, lets see: (vcliff pts2) # grep Documentation=

Is anyone using CentOS 4.4 with an EMC Clariion SAN? In particular, I want to know if PowerPath and Naviagent will work on a CentOS 4 system connected to a san using Qlogic or Emulex cards. I tried a couple years ago with Fedora Core 1 or 2, and couldn't get the kernel modules from PowerPath to work since the kernel wasn't the official RHEL one. I'm most interested in

I''m having following issue .. i import the zpool and it shows pool imported correctly but after few seconds when i issue command zpool list .. it does not show any pool and when again i try to import it says device is missing in pool .. what could be the reason for this .. and yes this all started after i upgraded the powerpath abcxxxx # zpool import pool: emcpool1 id:

Hi, I just deploy the ZFS on an SAN attach disk array and it''s working fine. How do i get dual pathing advantage of the disk ( like DMP in Veritas). Can someone point to correct doc and setup. Thanks in Advance. Rgds Vikash Gupta This message posted from opensolaris.org

I just installed EMC PowerPath 5.0.0 and Navisphere Agent and CLI on a CentOS 4.4/x86_64 system. When I try to start naviagent, I get the error below. Before upgrading to CentOS4.4, this same system had RHEL3 ES for x86_64 on it, and the same problem was encountered. I spent weeks going back and forth with EMC tech support, but the problem was never resolved. I'm hoping someone here on this

I'm looking into deploying * for an internal conference call server (using MeetMe) and had a couple of quick questions for those of you who have used it. I checked the Wiki but there weren't a lot of details for MeetMe. - Can you limit the size of a conference "room", ie max 8 people, etc. - Is there a list somewhere (besides the source ;) that has all the commands availible to
