From: "Ted Mittelstaedt" To: , Cc: Subject: Re: kern/11226: Invalid files on disk after fsync Date: Sun, 12 Sep 1999 00:20:39 -0700 Hi All, I was struck by the similarities between this and what happens with our news server. Once every 2 or 3 months I come in to find the server rebooted itself during the night - and I'm sure it's due to a SCSI error because the news spool is always scrambled. Usually, multiple invocations of fsck will eventually clear the garbage out but I've had to regenerate the spools once because of it. The only one time that I have ever seen anything in the message log regarding this is a rather cryptic log entry: Aug 11 06:12:59 herald /kernel: biodone: buffer already done This was made seconds before the system rebooted itself during one of those times. The server has done up to 2 million articles in a day and I'm sure that it's during the peak times that this has happened. I suspect there is some sequencing bug or other within the Adaptec SCSI driver - of course I'm running with all go-fast options turned on including async mounts on the spools.
