I am running 8.0 RC1 on a multi-user server with a few dozen vnet-enabled jails and netgraph. The swap partition is encrypted by its /etc/fstab entry, like:
/dev/ad2s1b.eli none swap sw 0 0 I am getting sporadic kernel panics on reboot, during the GEOM_JOURNAL shutdown sequence. However, they occur after geli detaches the swap partition, so I get an error like: Cannot dump. Device not defined or unavailable. I know I can set dumpdev in /etc/rc.conf to a file rather than a swap partition, but is there a way to (1) have an encrypted swap partition, and (2) dump a core to a swap partition without failure? If I set up a second unencrypted swap, I can't let the system write potentially confidential information into that space. Also, at the end of the panic, I get the message: Automatic reboot in 15 seconds - press a key on the console to abort but then the server hangs and requires manual power-down and reboot. I thought a reboot was inevitable after a kernel panic - that nothing could prevent it in terms of misbehaving processes, etc. Any idea what could cause such a freeze? Thank you. _______________________________________________ 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"
