Does anyone on the list have definitive information on whether ZFS works with CLARiiON devices? bash-3.00# uname -a SunOS XXXXXXX 5.10 Generic_118833-33 sun4u sparc SUNW,Sun-Fire-V245 bash-3.00# powermt display dev=all Pseudo name=emcpower0a CLARiiON ID=APM00033500540 [XXXXXXX] Logical device ID=600601607C550E00F25F4629AFBEDB11 [LUN 61] state=alive; policy=BasicFailover; priority=0; queued-IOs=0

Hello, I am using OpenSIPS to register all the users and planning to use asterisk for Auto Attendant, Queues, Voicemail and Conference Bridge. I have a scenario where the signaling does not happen properly: 1) A user from Opensips dials an extension 7000 which is an auto-attendant extension. The call is routed to asterisk to play the auto attendant messages like Welcome and Dial the

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

Does anyone know about this device? SESX3Y11Z 32 GB 2.5-Inch SATA Solid State Drive with Marlin Bracket for Sun SPARC Enterprise T5120, T5220, T5140 and T5240 Servers, RoHS-6 Compliant This is from Sun''s catalog for the T5120 server. Would this work well as a separate ZIL device for ZFS? Is there any way I could use this in a T2000 server? The brackets appear to be

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

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

I am [trying to] perform a test prior to moving my data to solaris and zfs. Things are going very poorly. Please suggest what I might do to understand what is going on, report a meaningful bug report, fix it, whatever! Both to learn what the compression could be, and to induce a heavy load to expose issues, I am running with compress=gzip-9. I have two machines, both identical 800MHz P3 with

I may be nuts, but... I would appear that rsync is not setting the exit code properly when it fails. Below are 2 cases where that seems obvious, the line with the '0' after the output is 'echo $?' from bash -- aka the exit code for the last command. Let me know if these are bugs, or I need to somehow get around these situations. Nic >>> starting rsync with

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, Is there a way to upgrade my current ZFS version. I show the version could be as high as 22. I tried the command below. It seems that you can only upgrade by upgrade the OS release.

I'm using an SVM as I've seen a paper that reported extremely good results. I'm not having such luck. I'm also interested in ideas for other approaches to the problem that can also be applied to general problems (no assuming that we're looking for spirals). Here is my code: library(mlbench) library(e1071) raw <- mlbench.spirals(194, 2) spiral <-

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

Hi. I'm trying to plot a pair of intertwined spirals and an svm that separates them. I'm having some trouble.

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
