Yes containers will go offline, but this fix is for a recent change to the driver; if it was 6 months ago, it was a totally different problem. You probably can resolve your problems by making sure you have the latest Firmware. I don't believe there are any changes in the driver in the past 6 months that would have worked around any Firmware/Hardware/Compatibility issues. Sadly, anything that goes wrong (including card, power supply, drives) can cause containers to go offline; it is a pretty generic symptom to a multitude of possible problems. Martin's initial problems were associated with using the WD JD drives, which are not compatible with RAID cards because their internal error recovery paths.

Would hitting this timeout issue cause the container to go offline? If so, I think this may fix the issues I was having 6 months ago. (We ended up taking the aacraid controller out of our production environment, in frustration.) I'll try to get some testing time in on this next week, though, the problems I've run into were very hard to reproduce on demand. -- Ryan Anderson AutoWeb Communications, Inc. email: ryan@xxxxxxxxxxx - : send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
