Re: [lustre-discuss] Restrict who can assign OST pools to directories

2022-11-07 Thread Raj via lustre-discuss
Marco, One other idea is to give an unfriendly pool name that users can't guess. Like "myfs.mkpilaxluia" instead of myfs.flash or myfs.ssd so that it becomes difficult(not impossible though) for users to use :). Users don't have access to MDS to get the entire lists of pools defined. Thanks, Raj

Re: [lustre-discuss] Disk usage for users per project

I do not think this exists yet. But, if every user has individual area(sub folder) inside the main project folder, can you create a ‘lustre project’ per project-user? -Raj On Tue, May 17, 2022 at 7:21 AM Kenneth Waegeman via lustre-discuss < lustre-discuss@lists.lustre.org> wrote: > Hi all, > >

One other way is to install xltop(https://github.com/jhammond/xltop) and use xltop client (ncurses based linux top like tool) to watch for top client with more requests per sec (xltop -k q h). You can also use it to track jobs but you might have to write your own nodes to job mapping script

Re: [lustre-discuss] Multiple IB interfaces

2021-03-11 Thread Raj via lustre-discuss
Alastair, Few scenarios which you may consider: 1) define 2 lnets one per IB interface (say o2ib1 and o2ib2) and share out one OST through o2ib1 and other one through o2ib2. You can map HBA and disk locality so that they are attached to the same cpu. 2) Same as above but share the ost/s from both
