Once this is installed you need to setup dm-multipath, look for
multipathd.conf in /etc, get the product id and vendor id from dmesg after
making an initial connection via open-iscsi and use that in the mutipath
config. Your going to need to use path utility 'rdac' in the config instead
of tur.

/etc/multipath.conf appears to be appropriately configured (we'd installed
the MDSM host components):
device {
vendor DELL
product MD32xxi
...
AFAIK the RDAC you have installed looks correct and the config also looks
good.
Thanks.
Did you start the multipath service make a connection to each IP and do a
'multipath -ll' and see what shows up?
Yes, and yes.
We've actually run some fairly intensive disk tests (bonnie++ and a few
tens of thousands of 100MB file copies of random data) with no errors
across various hosts.
The on-connect errors are the biggest issue we've got, though general
concensus seems to be that we can ignore these.
What's moderately maddening is the lack of any clear documentation or
guidance, from Dell, RH, or the upstream open-iscsi / multipath
projects, on what we should be experiencing, and what, if any, errors
are considered normal.
Think we've got a handle on it, but we're checking our sanity as well.

But my comment was not meant as a joke. By insecure, I mean that you don't mind that employee masquerades as another on your company's network. You therefore have no security and no accountability. No one should have access to anyone else's login. I have no admin privileges over my desktop. If I need something installed or uninstalled, I have to ask the Windows desktop support team who'll access my box remotely after I accept their request to a access my box in a popup on my screen. Of course, the Windows server support team can access my roaming profile on their boxes but (I presume since this is what we do and I don't know any of them to ask them) they'd have to justify that access. Yes, IT staff on a Windows Domain can access everyone's accounts, without their passwords or consent. Does it make it more secure? Yes. And No. IT staff can go rouge as well, just bear that in mind. Reminds me of a previous company I used to work for many years ago. Some of the IT admin scanned all incoming mail, especially if they contained any attachments. They casually copied whatever attachments they wanted to their own desktops, which was more often move clips, cracked games, music, pr0n, etc. Do you think management knew about this? Nope. Is it less safe than your environment? Really? Can you honestly tell me this doesn't happen in your company? You're confusing, as you have throughout this thread, an employee assuming someone's logon/identity on the network with an administrator accessing data on the servers that they manage. No one can or should be able to logon to the network with someone else's credentials. We have, AFAIK, two security teams that go through server logs and support tickets to reconcile them and to check that we aren't logging to boxes that we aren't supposed to have logged on to, checking whether we used su or sudo for a valid reason, and what we commands we've run while logged on. So we can't just go through data, confidential or otherwise, out of curiosity or with some bad intentions. So, no, there's no such activity on our network. Eleven years ago, I worked at a firm where the Exchange admins used to copy all the attachments that dealers and brokers received and burn DVDs for themselves, their friends, and for sale (!) with any porn-related files. There's no way that this is still happening. There's absolutely no reason to access a PC of a staff member who is busy, that's terrible practice; and there's absolutely no way that anyone should know anyone else's password (a punishable violation of IT policy in our environment). True, and that's not what I said either. Both the OP and I am trying to say that sometimes you need to get onto a PC when the user is not actually there. So why would you not want them to have password-locked screensavers. You either want to access that employees account or you want to access data on that computer by switching users. I've already covered the former and the latter simply shows that you're keeping data locally rather than on a server; not a good practice either... IF, on the other hand I worked at a financial institution or something like that then the security would have been more strict. I don't see the need for it in our office. I worked a few years ago, in between finance jobs, at a publisher who had similar rules. This is a standard for any properly-run IT department. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Could CentOS 5.5 on newer hardware make it freeze or shutdown?
Hi, I have built a new PC on which I've installed CentOS 5.5 64-bit (with updates) which after some hours of running suddenly either hard freeze or instant power off. The /var/log/messages log doesn't reveal anything of what has happened. The load has been either just idling or with moderate disc activities (transfers over 100GBit). Below is the hardware spec: Motherboard: Gigabyte GA-H55N-USB3 CPU: Intel Core i5 650 RAM: CORSAIR 8 GB RAM HDD1: Intel X25-M 80GB HDD2-7: Samsung ECHOGREEN 500GB ST LABS SATA/300 4-PORT PCI-E PSU: Corsair CX 430W I've also been running memtest86 for more than 24 hours without any errors. I was on my way to return either the motherboard or the PSU when I thought of installing Fedora 14 and give it a try. The PC has now been running for over 48 hours without any glitch, with varying load. I should also mention another problem that strangely disappeared with F14, and that was that the Samsung HDDs, which I have in a soft RAID6, now and then timed out (only one at a time). The message log showed a dump of NCQ queued commands, before it reconnected that disk. In F14 I haven't seen any errors at all in the log. Could those problems only relate to C5, or do you think I also have hardware problems and only been lucky so far with F14?

Re: [CentOS] Missing Dependency
I'm not sure what the problem is here. I asked a simple question. If I did not give enough or gave the the wrong information, a simple message to that end would have been good. I don't have a bunch of letters behind my name. I am almost entirely self taught. I started with Linux in 1995 on an old slackware server a very knowledgeable man built for me and was my remote lifeline for the first couple of years. Since then I have built and ran probably 15 Internet servers ranging from old slackware stuff to Redhat. I just retired my last Redhat 9 server a while ago. I currently have in service Gentoo, Fedora, CentOS and a Cacti Monitoring server that I can't remember the flavor of Linux they built it on. When I get a problem I don't know what to do, I Google or go to one of my many bookmarked sites. Or, I ask someone if all else fails. So, I was designing a Web Site and one of the scripts didn't work. Looking at the error logs and googling the error led me to determine my PHP needed an upgrade and even listed a painless way to do it. However, it didn't work because of a missing dependency. I had not found the answer about to how to fix the dependency problem and, I had joined this list about a week ago. I have been very impressed with the quality of most of the posts so I thought I would ask here. I am not really interested if the version of PHP came bundled with 4.8 or not. It seems it didn't. I probably upgraded it to fix another error I was getting. I thought I had given all the relative information with my first question. Sorry for bothering you.

Re: [CentOS] CentOS and Dell MD3200i / MD3220i iSCSI w/ multipath -- slightly OT
Hi, In last summer, I have had same problems with Dell + CentOS + multipath combination. For example I/O errors and stability problems on the initiator machines. The initator machines are (in a Pacemaker cluster): - Dell R310 - Broadcom 5709 Gigabit Ethernet card (4-port) - CentOS 5.4 - 2 Ethernet ports on initiator machines, 2 Ethernet ports in target machines -- 4 iSCSI pathes by initiators Irrespectively of iSCSI, we met the Broadcom MSI-X interrupt problem (corrected in RHEL/CentOS 5.5). We met more (iSCSI) problems with Broadcom cards, which are described on a Dell support page: http://support.dell.com/support/edocs/software/rhel_mn/rhel5_4/en/index.htm Since the CentOS is a recompiled RedHat, all RHEL problems and solutions are true for CentOS ;-) The Broadcom driver source code is frequently changed. RedHat follows the Broadcom kernel drivers and iscsi-initiator-utils with some months latency. CentOS follows the RedHat with some days/weeks/monts. Maybe you can find a solution for your problem on a newer Dell support page: http://support.dell.com/support/edocs/software/rhel_mn/rhel5_5/en/index.htm Or here: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/DM_Multipath http://opensource.marshall.edu/papers/rhel5-iscsi-HOWTO.pdf Some tips: - I've read somewhere about iSCSI multipath I/O errors, which can be a normal behaving in a multipath environment at boot time. (?) - Persistent reservation might be usefult against iSCSI multipath I/O errors. - Disabling iSCSI offload feature (for example: iSCSI over Broadcom ) and TCP offload feature (for example: NFS over Intel) may be helps. - The iSCSI kernel drivers and iscs-initiator-utils must be updated together. Finally, some comments: - Never use Broadcom GbE card. Intel might be better (mostly) - The Dell is hardware manufacturer (supplier), not an OS/driver/utility developer. If you would like to get more support, you may buy RHEL licenses (with the Dell hardware or from RedHat). Sometime it's cheaper than taking days for a problem (but sometime not). - IBM compiles the latest Broadcom driver if required, see: http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5073130 - Some Dell hardwares have only x86_64 RedHat certifications See: https://hardware.redhat.com/show.cgi?id=632145 (R310 + RHEL 6) BR, Peter On Sat, Jan 22, 2011 at 18:36, Rajagopal Swaminathan raju.rajs...@gmail.com wrote: Greetings, On 1/22/11, Edward Morbius dredmorb...@gmail.com wrote: CentOS is not a Dell-supported configuration, and we've had little helpful advice from Dell.
