Please work with Red Hat support to open a ticket - they can help us collect information that is needed for debugging issues. Thanks! Don't have a RHEL support contract and not sure how to contact/work with Red Hat support. Am willing to do what I can to help you reproduce this as fixing it will benefit all. This was experienced on a CentOS box. Red Hat bugzilla is normally used to help our support people work with our customers. If you don't have a subscription, I think that the best thing would be to have you report issue to the right upstream mailing lists (linux-ext4 in this case). For those reports, please put in lots of detail - type of machine (cpu type & count, DRAM amount, type of storage) - and the backtrace from the crash. Thanks! |
Created attachment 479222 [details] screen capture of crash Description of problem: When running a heavy load (db2 load) against several 1TB ext4 partitions the box will consistently hang/crash. How reproducible: 6 times over 2 days Actual results: See screenshot. Expected results: System doesn't crash Additional info: When runing the exact same load using xfs instead of ext4 the system has no issues.
