as we are about to throw users onto the new system, can I ask for a quick update pointing us to the current best guess at a workaround/fix for the 1.8.1 read cache problems please? to me it looks like https://bugzilla.lustre.org/show_bug.cgi?id=20560 is still evolving, but it looks like writethrough_cache=0 should now work (and not crash the OSS) with attachment: https://bugzilla.lustre.org/attachment.cgi?id=25833 so if I patched our OSS's with just this one liner, then would that be enough to run with until the situation has had some time to bed in? or would we be better off with all 4 patches from 20560 applied (and both read cache's still off)? cheers, robin -- Dr Robin Humble, HPC Systems Analyst, NCI National Facility _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
