According to http://docs.sun.com/app/docs/doc/819-5461/gdswe?l=en&a=view , the zpool history file is between 128K and 32MB, depending on the size of the pool. The FreeBSD import at /sys/cddl/contrib/opensolaris/uts/common/fs/zfs/spa_history.c agrees with the docs :) -- Dan Nelson dnel...@allantgroup.com _______________________________________________ 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"
