Dear pnfs developers,
I would like to confirm client behavior which was hurting us for years. If for some reason the client is unable to connect to a DS, then this DS got blacklisted and the only way to whitelist it again was client reboot. With RHEL7 (and I believe with upstream kernel), after 2 mins client 'forgets' about bad DS and uses it again. This behavior is tested and confirmed during June bakeathon. Missing bits: i) it takes client 6 min to fall back to MDS, e.g time between LAYOUTGET and first WRITE to MDS ii) there are no log entries why client have decided to use MDS Thanks, Tigran. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
