I'm not sure I understand this. How would that negatively affect the raidz1? The swap isn't in the zpool. I understand the system may crash if the OS was using the swap space and the drive failed. But would you not be able to reboot into a degraded zpool state and still have a usable system? _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
