Re: [lustre-discuss] lnet router lustre rpm compatibility

The only requirement for upgrade ordering in the past was during the 1.8->2.x upgrade. In that case, 1.8 clients could connect to both 1.8 and 2.x servers, while 2.x clients can only connect to 2.x servers. Since then there isn't a hard requirement for upgrade ordering, though we only test a

I checked the output of dmesg and found lnet: Unknown parameter `#’ The error was caused due to a comment that was inserted in /etc/modprobe.d/lustre.conf Thanks a lot for your time and your help. > On Jun 22, 2016, at 4:03 PM, Patrick Farrell wrote: > > OK, that's not the

Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

OK, that's not the error we started with. You were having a problem loading modules, but aren't now. (probably) The error output from that command is bad. It asks if the modules are loaded, but that doesn't mean they aren't. "No such device" is probably the key here. I'd look at the

Ah, now that I look more closely - that warning may not be fatal. Did you get a failure, or just the warning? (The guide looks good) On 06/22/2016 02:52 PM, Sangeetha Banavathi Srinivasa wrote: Patrick, I am following the steps on

Patrick, I am following the steps on http://lustre.ornl.gov/lustre101-courses/content/C1/L3/LustreBasicInstall.pdf Except that I am installing 2.8 instead of 2.7. Could you recommend any other article/blog that I can follow in order to successfully install lustre. > On Jun 22, 2016, at 3:43

Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

Well, that's not patching the kernel. It's making the initrd and and updating the boot stuff so your system will boot that kernel. But, yes, that should be what you need to do. - Patrick On 06/22/2016 02:36 PM, Sangeetha Banavathi Srinivasa wrote: When you say install the associated kernel do

Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

The kernel version is found with uname -r or cat /proc/version. That needs to match the kernel version in the Lustre RPMs. (The version string is the 2.6.32-573.12.1.el6_lustre) part. In fact, it looks like you've got Lustre server RPMs, given the _lustre in the name of the kernel. That

Re: [lustre-discuss] MDS Config Help: Are the lustre modules loaded?

Well, it says to check dmesg... Though that will just list the symbols. In general, this usually means you've got a mismatch between the version of the kernel (or OFED) Lustre is built against and your version of either the kernel or OFED. Given the number and locations of the mismatches,

Hi Yasir. You must add the lustre packages to the distribution following the rocks manual: http://central6.rocksclusters.org/roll-documentation/base/6.2/customization-adding-packages.html Finally you must add the lustre network and configure the compute network interfaces that you will use
