[lustre-discuss] old Lustre 2.8.0 panic'ing continously

[Degremont, Aurelien]

I understand you want to avoid deploying kdump, but you should focus on saving your console history somewhere. It will be difficult to help without the panic message.

For 2.10, maybe I was a bit optimistic. I think you should be able to build the RPMs from sources, but pre-build packages are not available.

    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 :-(
    
    > - It seems related to quota. Is disabling quota an option for you?
    
    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
