[lustre-discuss] Group and Project quota enforcement semantics

2019-08-05 Thread Steve Barnet
Hi all, I am starting to work with project and group quotas since they seem like they would be a good fit for one of our newer filesystems. I think that I have the system configured correctly, and project quotas enabled on all OSTs and the MDT (lustre version 2.12.2). Basic tests appear to

2019-01-23 Thread Steve Barnet
Hi all, Since early last summer, we have been running a 2.10.4 filesystem pretty much without incident. Then about 2 weeks ago, it started crashing for no immediately obvious reason. There are no indications of hardware related problems in the logs, and the work loads have not changed

Hi all, We have a multipath OSS->OST hardware configuration which, in principle, allows us to move OSTs between OSSes if/when we need to do maintenance. In general, this has worked very well for us. However, today when I needed to do some maintenance, I discovered that we have a set of OSTs

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 ___

Hi all, This is Lustre 2.8.0 community edition, combined MGS/MDT. I was adding storage to a filesystem and mistakenly duplicated an index for one of the OSTs at creation time. Since these OSTs were new and no data had been written, I made the mistake of reformatting the affected OSTs
