I’ve created a Benchmarking process outline and tools overview here: http://wiki.lustre.org/Category:Benchmarking This has been recently updated and is based on notes I’ve maintained at Intel over the years. Malcolm Cowe High Performance Data Division Intel Corporation | www.intel.com From:

Re: [lustre-discuss] lustre client 2.9 cannot mount 2.10.0 OSTs

Lustre file system names cannot exceed 8 characters in length, but “scratch12” is 9 characters. Try changing the fsname to a smaller string. You can do this with tunefs.lustre on all the storage targets, but I can’t remember if you need to use --erase-params and recreate all the options.

I'm going to be testing an upgrade of a filled 2.9/0.6.5.7/CentOS6.x LFS to 2.10/0.7/CentOS6.9. I will report back results to the mailing list when it is completed. --Jeff On Mon, Aug 7, 2017 at 06:50 E.S. Rosenberg wrote: > We created a test system that was

Re: [lustre-discuss] Lustre 2.10 on RHEL6.x?

We created a test system that was installed with CentOS 6.x and Lustre 2.8 filled with some data and subsequently reinstalled with CentOS 7.x and Lustre 2.9 Everything seems to have gone fine but I am actually curious if anyone else did this pretty invasive upgrade? (Hoping to upgrade in the

Re: [lustre-discuss] Lustre 2.10 on RHEL6.x?

Correct – RHEL 6.x support appeared for the last time in the community 2.8 release. However, there has been some interest in seeing some kind of support for RHEL 6.x in the 2.10 LTS releases so I think it likely that at least support for clients will be reintroduced in a future 2.10.x

[lustre-discuss] Lustre 2.10 on RHEL6.x?

Hey all, I am looking to upgrade from lustre 2.8 to 2.10. I see that there are no pre-built RPMs for 2.10 on RHEL6.x families. Did I miss them, or will I need to build from source (or upgrade to Centos 7)? Thanks much! Best, ---Steve ___

I do apologize. This was my error – I seem to have sent it to lustre-devel twice when I intended to send it to both lustre-devel and lustre-discuss. On 8/7/17, 5:56 AM, "lustre-discuss on behalf of E.S. Rosenberg"
