Over the past two weeks we have experienced Oakely login node crashes potentially caused by a Lustre bug. The bug (or issue otherwise) seems to be activated when a user does operations on a lustre directory that contains an excessive number of files (10000+ files).
Our support contacts have been contacted and we are working with them to resolve this issue. Updates will be posted both here.
Users should be aware of the increased vulnerability of Oakley's login nodes and save more often until the issue is resolved. Users should also actively work to avoid directories with large file counts (large == 10000+ files). Please contact OSCHelp@osc.edu if you would like assistance splitting up your large directories.
