I have a FreeBSD-based web/ftp server that is crashing regularly, and the crashes are causing (caused by)file system corruption. I'm suspecting (and hoping) that it's just a configuration problem, or a known bug with an easy workaround. I'd hate to learn that there was something inherently wrong here! Here are the details, hopefully someone will recognize the issue: * The server hardware is an Intel N440BX motherboard, with two Intel Pentium III 450 processors. 256 megs of RAM. Built-in graphics, and a PCI NE2000 Ethernet card (the built-in EtherExpress interface wouldn't work for me, another story, another time). * The disk subsystem is a SCSI RAID controller from DPT. It's a PCI card and has 4 drives attached, configured in a RAID 5 with one drive as a hot standby. * FreeBSD is version 3.1-STABLE-05051999, with the kernel recompiled for SMP support. * The server worked fine for me as I was installing and upgrading it, adding and compiling additional software, uploading megabytes of data to the ftp directories, etc. * The server also had no difficulties when I sent out a company-internal e-mail with a request to bang on it. That's a load of about 30 users at any give time (http only, though). * We put it into production use as our main web server on Wednesday night. It handled quite a high load as people checked out the new site design. * Thursday night was the first crash, we don't know what caused it. The server rebooted, but fsck failed on /home, and so it didn't come up automatically. Manually running fsck fixed the errors, with a few files recovered to lost+found. * The next morning while examining the files in lost+found, doing a cp of one of the files, the server crashed again. This time it rebooted itself, found no file system problems, and came up. * Last night (Saturday at 5:30am, actually) it failed again. This time there are file system errors on /usr and /home. fsck fixed the problems on /usr and most of them on /home, but now we're getting an error about a bad sector. /home obviously refuses to mount. Anything known about problems in FreeBSD-STABLE with SMP configurations and RAID sub-systems? Or other obvious (or subtle) problems? Thanks much! Michael === --- Michael A.
