Hello! I am trying to find a way to avoid filesystem corruption after system crashes. I am using FreeBSD 7.3 with DDB enabled. Sometimes system freezes and only DDB (via CTRL-ALT-ESC) is available.
Documentation says there is 'call boot(0)' function that performs graceful shutdown from DDB. To test it, I set up fresh install of FreeBSD 7.3 on a new server. Then I started background 'tar -zxf ports.tar.gz' on all partitions: /home, /usr, /var, /tmp and finally /. Waited ~30 seconds and pressed CTRL-ALT-ESC -> call boot(0) -> Enter. Unfortunately, DDB freezed on syncing bufdaemon. I had been waiting for ~5 minutes, but system freezed completely: I could not drop to DDB anymore and keyboard was not working. I had to restart by reset. What can be the reason of this last system freeze? I am using Adaptec controller 3405 with FreeBSD's driver, can it be the cause? I do not know indeed how to ask a good question about this situation because I have no more ideas. Any help would be appreciated! -- cronfy _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
