Fail to create OCFS volumn on the hard disk via a QLA2312 fiberchannel card.
/dev/rawctl is part of the "raw block device" driver interface. You need to turn on the raw device driver option (CONFIG_RAW_DRIVER) in your kernel build. I have always created a new file system from my 2.4 kernel (that has all possible modules built and properly configured to load when needed), so I don't know for sure if mkfs.ocfs will work correctly after turning on the raw

zfs in san
I am planning to use zfs with fiber attached san disk from a emc symmetrix''s Based on a note in the admin guide it appears that even though the symmetrixs will handle the hardware raid it is still advisable to create a zfs mirror on the host side to take full advantage of zfs''s self healing/error checking and correcting. is this true ? Additionally I am wondering how the zfs

ZFS panics solaris while switching a volume to read-only
Hi, I just found out that ZFS triggers a kernel-panic while switching a mounted volume into read-only mode: The system is attached to a Symmetrix, all zfs-io goes through Powerpath: I ran some io-intensive stuff on /tank/foo and switched the device into read-only mode at the same time (symrdf -g bar failover -establish). ZFS went ''bam'' and triggered a Panic: WARNING: /pci at

Multiple OCFS intances in the same LAN
Hi, is it possible and safe to use more than one RAC-Cluster using OCFS in the same LAN? I'm considering to following setup: a 2-node production and a 2-node test system, the production data is stored in an EMC Symmetrix and for the test-system the production data is copied once to a BCV disk internally. This will give me an new independant copy of the production disk with the same contents,

ZFS and powerpath
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:

ext3 and 64 bit addressing
Dear List People: I am doing some comparisons of different fs's and need to know where ext3 stands in terms of 64 bit addressing. XFS and JFS claim to be full 64 bit systems (though are there not still kernel limitations that would, for the time being, reduce the ability to use a full 64 bits?), what about ext3??

ZFS vs mpxio vs cfgadm in Solaris.
Folks, I''m trying to figure out whether we should give ZFS / mpxio a shot on one of our research servers, or simply skip it (as we have previously). In Nov 2009 Cindy responded to a thread concerning ZFS device issues, cfgadm, and mpxio: http://mail.opensolaris.org/pipermail/zfs-discuss/2009-November/033496.html I''ve got an x2270 with the Sun EZ-SAS HBA and external SATA

cfgadm, luxadm changes in OpenSolaris Development snv_128a
We recently upgraded last week to OpenSolaris Development snv_128a and all things went fine, zpool still works, etc. Our disks come off a Hitachi Disk Array and we have 2 qLogic fiber cards in our server. "cfgadm -al" use to report the cards and "luxadm probe" use to return all the disks on the array. "luxadm probe" now returns "ERROR: No Fibre Channel Adapters

Problems with custom service and webrick
Hi all, Windows XP Pro Ruby 1.8.2 I''m having a couple of problems with the following service. The first issue is that the code in service_start doesn''t seem to fire off. The second problem is that any attempt to do ''require "webrick"'' within webrick_daemon.rb causes the service to fail on start. Any ideas? # webrickctl.rb

Performance problem with CentOS and XFS on EMC
We have an appliance that uses the CentOS 4.4 Plus kernel with XFS on an EMC RAID array that performs about ? or less as well with cached i/o than with direct i/o. With direct i/o we get about 32Mb/s throughput or better, but if we enable the cache for the EMC RAID, we only get 8Mb/s or less. This doesn't happen if we use JFS, where we get a little less than 32Mb/s throughput with or without

CentOS and EMC PowerPath/Naviagent
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

EMC migration and zfs
We are going to be migrating to a new EMC frame using Open Replicator. ZFS is sitting on volumes that are running MPXIO. So the controller number/disk number is going to change when we reboot the server. I would like to konw if anyone has done this and will the zfs filesystems "just work" and find the new disk id numbers when we go to zfs import the pool. Our process would be: zfs

Does EMC use Samba for CIFS?
I have heard that EMC might be using a port of Samba for their CIFS protocol. Can anybody support or refute this? Are there any commands that can be issued or any operations that can be performed and sniffed to verify this one way or the other? Thanks, Paul

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

EMC Clariion stanby power supply
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
