Sorry for the off-topic question but I need advice on a buying a ISCSI SAN for 4-6 servers running CentOS 4.4 .The main purpose for the SAN is to store email accounts (that will be accessed by imap - dovecot) and other documents. Minimal redundancy is required (e.g. dual power supplies, battery backed write cache or mirrored controllers) and price for a 2 TB configuration should be under $ 10000.

We're having a problem with Linux and/or the SCSI controller failing to access an external RAID device. Components are: SuperMicro 6025B-TR+V CentOS 5.0 with yum update as of a week or two ago (kernel 2.6.18-8.1.8.el5) Promise Vtrak M310p Adaptec 29320 LPE -- aic79xx module Sometimes this fails on the initial device probing (before the kernel even begins to boot); sometimes the device is

Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

hi all We have a rh linux server connected to two HP SAN controllers, one an HSV200 (on the way out), the other an HSV400 (on the way in). (Via a Qlogic HBA). /etc/multipath.conf contains this : device { vendor "(COMPAQ|HP)" product "HSV1[01]1|HSV2[01]0|HSV300|HSV4[05]0" getuid_callout "/sbin/scsi_id -g -u -s /block/%n"

The reason for the behaviour observed below turned out to be that the device entry in /etc/multipath.conf was inadvertently appended *after* the devices section , rather than inside it - so that we had #devices { # device { # blah blah # } (file has a bunch of defaults commented out) # etc #} # # device { our settings } *rather than*

--Apologies if you get two copies of this message - it was submitted for moderation and hasn''t appeared on the list in two days, so I''m resubmitting. Hi all, Just a quick question. Is it possible to utilise an Apple Xserve RAID as an array for use with ZFS with RAID-Z in Solaris? I''ve seen various mentions of ''zfs'' and ''xserve

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

My network currently uses samba version 3.0.14 and doesn't seem to have any problems but alot of my logs repeat the following error message: [2005/08/09 09:29:42, 0] rpc_client/cli_trust.c:change_trust_account_password(248) 2005/08/09 09:29:42 : change_trust_account_password: Failed to change password for domain SPICE.

I need to replace a slow HP MSA20 that's a bottleneck right now (We are an HP shop). HP's only option with 3.5" SATA drives is stuck at SATA I behind a SAS controller. Dell makes an MD1000 that claims SATA II speeds behind a SAS Perc 5/E (Don't know anything about dell). Anyone got any real world info they can share? I need 3.5" SATA II at least 12 drives behind SAS, I am

hello! Can someone point me to some best practices in building high-available scalable mail system or! share your own success stories. I've read article in LJ "Building a Scalable High-Availability E-Mail System with Active Directory and More" but it seemed to be outdated and there's a single point of failure (Master node). What I want to achieve: high-available,

Tired of "little problems" trying to keep 7 drives working in an old desktop computer, I'm considering an external SATA drive enclosure with a controller card based on the Sil3124. http://www.ipcdirect.net/servlet/Detail?no=152 I'm a bit concerned about long-term support, namely that the company's driver page only lists drivers through RedHat 4.

Hi all,? I have a CentOS 4.5 server running on a workstation mainboard (PCI Slots only).? We have now one 200 Gigs IDE disk dedicated for e-mail server storage.? We use Communigate Pro and the server has 45 Outlook clients with the MAPI connector (All mailboxes on the server).? When a user opens Outlook, a refresh of the local cache is performed for his data.? There is a big "Public"

Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim

Hi all. While playing with iSCSI Enterprise Target + multipathd on CentOS 5.1 (both the target and the initiator/multipath/xen box are Cent 5.1), I encountered a strange fault condition that leads to a kernel panic in a version of Xen 3.2.1-rc2 pulled from a couple of days ago. My lab consists of two Clovertown machines with dual GigE into separate switches. The target box is softraid5

Hello, I'm trying to use smbutil with the user/pass/host argument. I have no problem using it this way.... smbutil -v view //user@host Password: ******* but if I try this way.... smbutil -v view //user:pass@host it prompts me for a password when I already specific it in my command line. Am I using the right syntax? Please let me know. Thanks. Tom

apparently if you don''t order a J4200 with drives, you just get filler sleds that won''t accept a hard drive. (had to look at a parts breakdown on sunsolve to figure this out -- the docs should simply make this clear.) it looks like the sled that will accept a drive is part #570-1182. anyone know how i could order 12 of these?

Hi, I was wondering if anyone has successfully configured two lsi/3ware 9750-4i series controllers for multipathing under CentOS 5.7 x86_64? I've tried some basic setups with both multibus and failover settings, and had repeatable filesystem corruption over a iscsi(tgtd) or nfs3 connection. Any ideas? Vahan

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

Hi all, I am trying to configure a failover multipath between 2 GNBD devices. I have a 4 nodes Redhat Cluster Suite (RCS) cluster. 3 of them are used for running services, 1 of them for central storage. In the future I am going to introduce another machine for central storage. The 2 storage machine are going to share/export the same disk. The idea is not to have a single point of failure
