Thanks Cindy, In fact, after some research, I ran into the scrub suggestion and it worked perfectly. Now I think that the automated message in http://www.sun.com/msg/ZFS-8000-8A should mention something about scrub as a worthy attempt.
It was related to an external usb disk. I guess I am happy it happened now before I invested in getting a couple of other external disks as mirrors of the existing one. I guess I am better off installing an extra internal disk. is this something common on usb disks? would it get improved in later versions of osol or it is somewhat of an incompatibility/unfriendliness of zfs with external usb disks? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
