You might want to try a reboot of the system. There is some low level caching of the encryption key in the kernel. I noticed that you can remove the key and continue to mount and umount it without a key so long as you do not reboot. Maybe this will clear it up. I never recommend "just reboot" however, in this case it may actually work.
Thanks but this doesn't help. This is not a "production" server, but a home based one that is powered down several times per week. The system went through many reboots both before and after the problems started. -- Roberto Waltman _______________________________________________ zfs-discuss mailing list firstname.lastname@example.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
