I recalled this problem was reported last month -- thread "File system becomes read-only", to which you contributed. No solution was posted to the list, no one mentioned anything about a bug report, and I cannot find any bug report summaries that look even remotely close to the problem.

There is a thread on Dell about problems with the MegaRAID sas driver (module name megasas) -- http://lists.us.dell.com/pipermail/linux-poweredge/2007-March/029974.html -- but you have not given enough information for anyone to know if this is relevant to your problem. Grep /var/log/messages for "megasas". One writer in that thread (on Dell) writes "the problem is that the Linux kernel's SCSI layer insists on a single timeout for all SCSI requests, and doesn't tolerate high variances in command completion times. If any single command times out, it resets the whole bus, even if there is still significant activity." This suggests that the problem is more widespread than just a RAID issue. This is that writer's message -- http://lists.us.dell.com/pipermail/linux-poweredge/2007-March/029982.html -- and it contains a suggestion that may be of use to you. You'll need to give us a lot more information about your system hardware (including the modules that are loaded for hard drive i/o), plus information from /var/log/messages about what is happening when the filesystem goes RO. -- Hypocrisy is the homage vice pays to virtue. -- François de La Rochefoucauld -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
