March 2014 - HPDD-discuss

by Matt Bettinger

Hello, We currently run 2 lustre file systems 1.8.6 (qdr) and 1.8.8 (fdr). We will be taking 1.8.6 off-line for an "upgrade" ( bare metal reinstall of OS and lustre!) to 2.X. I see quite a bit of activity on different releases which is a confusing as to decide which release to install. What is the main 'stable' release that is suggested for a new 2.X installation? 2.5? We are interested in looking at the newer tools such as lester, robinhood, latest collectl, and the HSM bits. The interconnects are Mellanox QDR to a very finicky IBM IB switch and fibre back end. The OS is going to be RHEL or CentOs but does not matter however we would prefer to use the lustre RPMs if possible so 6.4/6.5 I am guessing. We have two MDS available on this system as well. It is not a requirement that the 1.8.8 be able to talk to 2.X through Linux gateway routers but things change and we may need to have 1.8.8 cross mount the new 2.x. Does that have any bearing on which 2.X version we decide to land on? Thanks~ Matt Bettinger On Fri, Mar 14, 2014 at 2:05 PM, Jones, Peter A <peter.a.jones(a)intel.com> wrote: > > Hi there > > Here is an update on the Lustre 2.6 release. > > Landings > ======== > > -A number of landings made http://git.whamcloud.com/?p=fs/lustre-release.git;a=shortlog;h=refs/heads... > > Testing > ======= > > -Testing has continued on the 2.5.56 tag >

I had similar problems after a crash of my OSS.

Re : Re: Lustre 2.2 on RHEL 6.4 with infiniband

by Harry H

Hi everyone, Thanks for your answers. I plan to install lustre 2.2 because i have clients on rhel 5.5, by seeing the lustre matrix, it seems i'm stuck on lustre 2.2, or 2.3 if i upgrade my clients to rhel 5.9, isnt'it ? Is there any problems with this lustre release ? --- Message initial --- De : "Dilger, Andreas" <andreas.dilger(a)intel.com> Envoyé : 13 mars 2014 23:20 A : "Harry H" <laurus3000(a)hotmail.com>, hpdd-discuss(a)lists.01.org Objet : Re: [HPDD-discuss] Lustre 2.2 on RHEL 6.4 with infiniband On 2014/03/13, 2:07 PM, "Harry H" <laurus3000(a)hotmail.com<mailto:laurus3000@hotmail.com>> wrote: I plan to install lustre 2.2 on RHEL 6.4 with infiniband. I would ask why you are installing Lustre 2.2 at this point? That is an old version of Lustre for which no maintenance releases was or will be made. Better to stick with a version like 2.4 or 2.5 which will have maintenance releases with bug fixes. Cheers, Andreas Does i have to use the driver include in RHEL or install mellanox OFED ? If i'm not wrong, RPM from whamcloud are built against infiniband driver included in RHEL6. Is there something specific to install ? Thanks.
