[Torsten Harenberg]

Hi Aurélien,

thanks for your quick reply, really appreciate it.

a running ssh shell only shows

kernel panic - not synced.

No trace, nothing. I will try to capture the console next time that happens.

yes.. though not deeply. Was difficult, as kdump is not installed on
that one and I was a bit afraid to deeply touch the system as we bought
it pre-installed and the kdump-tools are not installed and /var/crash is
empty, so I fear kdump was not configured :-( So my only knowledge is
that the kernel panics :-(

not easily, the system is always full and enforcing group quotas was our
way so far to keep the system from physically reach 100%. But of course
we could talk to the users and ask them to behave nicely.

That would be great!!!!!! Where do you find the server RPMs for this
version? I couldn't find them on whamcloud:

https://downloads.whamcloud.com/public/lustre/lustre-2.10.8/

only contains server RPMS for el7 as far as I can see.

Thanks again

 Torsten
