Nobody snipped attributions, and even if they did, get over it.

No. I don't know how to resolve this - I also have Solaris 10/09, and it's somewhat a regular occurrence for the system to halt and refuse to come up, because something went wrong with the external nonredundant zpool. Namely ... the power got accidentally knocked off the external device. Or the device enclosure failed. Or something like that. So I have to do as I said, power cycle, go into failsafe mode, do a "zpool import" and I'll see the external pool "is in use by system blahblahblah" And then I "zpool import" it, with the -f or -F, and init 6. And then the system comes up clean. I don't know why my experience is different from Robert's. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
