similar to: OCFS and multipathing

Hi, I do have one iscsi storage with 4 GBit nics of which currently only one is configured with an ip and which is in productive use by one cent os 6.3 server. Doing some research brought me to the idea to use some nic bonding or multipathing for that storage, but multipathing I did about four or five years ago only once :) Furthormore I can't find the ultimate answer (may be there is not

Hi list! I have a server with dual port Qlogic iSCSI HBA. I set up the same LUN for both ports, and boot the CentOS installer with "linux mpath". Installer detects multipathing fine, and creates mpath0 device for root disk. Installation goes fine, and the system boots up and works fine after the install from the multipath root device. After install the setup is like this: LUN 0 on

First, I am new to Xen.... So forgive me if I am overlooking something. Here is my situation, I have multiple dom0''s that are part of an ocfs2 cluster. The dom0''s mount multiple volumes (/home, /app, /images) from an ISCSI storage array. Their eth2/eth3 network interfaces are attached to a private storage network. They are not part of Xen''s network bridge and have

hi. i've looked for (and not found) an assert() function. needing one, i created the following (from stop()). i'm posting it in case 1) someone sees a problem with this; and 2) someone else has a need. cheers, Greg ---- ## an assert mechanism... assert <- function (shouldbe, ...) { if (!shouldbe) { .Internal(stop(as.logical(TRUE),

Hello all, I have been doing some searching for information about disabling services within a CentOS 5.5 install. I have found a few different opinions, and wanted to ask for some feedback. First off, the system is running a LAMP stack to serve a web application. It will only be doing email to send occasional messages out (sent via the application only). It will not be receiving email for any

I'm trying to test out an Equallogic PS5500 with a server running CentOS 4.7 I can create a volume and mount it fine using the standard iscsi-initiator-utils tools. The Equallogic box has 3 Gigabit interfaces and I would like to try to set up things so I can read/write from/to the volume using multiple NICs on the server i.e. get 200+ Mbyte/s access to the volume - I've had some

Hi, Some body know how to attach a LUN directly to an VM? Is two node pool with storage over multipath FC tied by an Qlogic hba. I''m using lvmohba with out problems, but I want to assign it directly to VM to increase the throughput. Thanks for the advice. -- Atentamente, Julian M.

I successfully have OCFS running in a two-node RAC environment using RHAS 3 (2.4.21-4.EL) using Qlogic 2310 cards. IO performance, however, was terrible with the combination of OCFS and the Qlogic cards. After extensive testing, OCFS did fine on its own, as did the fibre cards. Put the two together, and everything literally ran twice as slow. Support at Qlogic pointed me to

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not

Hello, I hope to be in the right list. my question is the following. I can''t seem to get multipathing configure on XCP 1.6. In XenCenter I was able to enable "Multipath" however, in the LUN under general tab I see " multipath 1 of 1 active", the the CLI I do the following command xe --m node session it list only one session. Can someone help me please? Thanks in

Sort of a followup... We've been running OCFS in sync mode for a little over a month now, and it has worked reasonably well. Performance is still a bit spotty, but we're told that the next kernel update for RHEL3 should improve the situation. We might eventually move to Polyserve's cluster filesystem for its multipathing capability and potentially better performance, but at least we

Hi all- Usually i call out on this list for help on the CentOS matters but today I am fishing around trying to find an active forum for Solaris. It's hard to match the community here but I'd like to find the Solaris list where the most people are. Just having trouble configuring multipathing on QLogic iSCSI HBA's on Sparc_Solaris10. Thanks in advance- -rickp -------------- next

Dear list, we have a relatively new Sun Storage 7310, where we connect CentOS 5.5 Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades boot from SAN via qla2xxx, and have no harddisks at all. We want them to use multipathing from the very beginning, so /boot and / are already seen by multipathd. Problem is, that the Sun 7310 has two storage heads which run in

I've been reading this group for a while and I've noticed a variety of comments regarding running OCFS on top of path-management packages such as EMC's Powerpath, and it brought to mind a problem I've been having. I'm currently testing a six-node cluster connected to a Hitachi 9570V SAN storage array, using OCFS 1.0.12. I have six LUNs presented to the hosts using HDLM,

Hello, I have two OCFS file file systems mounted at /ocfs_1 and /ocfs_2. I have unmounted both OCFS file systems and was trying to then offline and unload OCFS. The offline command failed with - # ./o2cb offline Stopping O2CB cluster ocfs2: Failed Unable to stop cluster as heartbeat region still active Looking at the processes on this box shows a number of OCFS processes are still active -

/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
