similar to: ZFS on CLARiiON SAN Hardware?

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:

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

Hello All. I'm working on building support for the Clariion range of standby power supplies. I've found you can get hold of these easily on ebay like: http://www.ebay.co.uk/itm/EMC-CLARiiON-Standby-Power-Supply-118031985- SPS-1000W-/160373295258 There is a problem that I haven't been able to work around. After 90 seconds without power, the device shuts down. This is because

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

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

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

I'm looking for RAID options for at least 10 TB to attach to a Dell PowerEdge 2950 running RHEL 5 64-bit Server. The system will act as a single sign-on server for XP and Linux, thus storing user's data from mounted home directories exported from the server to various workstations. It may also house a database. I'll need a storage solution starting at least 10 TB. Most of the

hello folks, I am running Solaris 10 U3 and I have small problem that I dont know how to fix... I had a pool of two drives: bash-3.00# zpool status pool: mypool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM mypool ONLINE 0 0 0 emcpower0a ONLINE 0 0 0 emcpower1a ONLINE

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

Hi all, I'm troubleshooting an ocfs2 performance problem where creating files in a directory containing ~180k files is taking significant time to complete. Sometimes creating an empty file will take >100 seconds to complete. This is a three node cluster. I'm currently running OCFS2 1.2.3-1. Are there any changes in a recent version that may address this issue? What should I look

Hi, We are running a server as an nfs head connect to a clariion, every couple of days we have our box fall over with the following msg in syslog.

We are running a benchmark that does single threaded 512 KB writes to a LUN on a CLARiiON storage array. The dual Xeon host (Dell 2650) with 4 GB of memory runs RHEL 4U3 We measured the write bandwidth for writes to the block device corresponding to the lun (e.g. /dev/sdb), a file in an ext2 filesystem and to a file in an ext3 file system.

Hi We've been using Dovecot as our primary IMAP and POP3 server for around 70,000 users for a couple of months now. On the whole, we've been very pleased with the performance of Dovecot - and are extremely grateful to the developers! However, we have had a few issues, some of which we have yet to resolve. We chose Dovecot because it was the only IMAP/POP3 server we could find that

Please reply to david.curtis at sun.com ******** Background / configuration ************** zpool will not create a storage pool on fibre channel storage. I''m attached to an IBM SVC using the IBMsdd driver. I have no problem using SVM metadevices and UFS on these devices.

Hello, I know, that you had this discussion a view days ago but I''m in the installation phase of our new production servers and I intend to migrate the data from UFS volumes to ZFS volumes in near future. For doing this it must be ABSOLUTELY sure that I can resize the SAN LUNs because during the last 4 years I had to double the LUN size every year. I tried to resize a test volume

If anyone is running this configuration, I have some questions for you about Page83 data errors. This message posted from opensolaris.org

I have the following configuation. My storage: 12 luns from a Clariion 3x80. Each LUN is a whole 6 disk raid-6. My host: Sun t5240 with 32 hardware threads and 16gig of ram. My zpool: all 12 luns from the clariion in a simple pool My test data: A 1 gig backup file of a ufsdump from /opt on a machine with lots of mixed binary/text data. A 15gig file that is already tightly compressed. I wrote

That should say below, we are using Powerpath on the CX300's AND the CX600's... ----------------------------------------------------------------------- We are using Powerpath with CX300's and Emulex HBA's, also with OCFS on Red Hat 2.1 AS. Kernel upgrades are the biggest issue that we have, as some of the drivers are dependent on modules built for specific kernels, and if your
