I mean, who is using hardware raid to create a 8.5GB "disk" > then create a zpool with that one "disk"? You mean 8.5TB. Believe it or not, a) You can buy 1 TB drives off the shelf so you need only 8 or 9 of them to reach that capacity, and 9 drives is a trivially small number in serious installations. b) Hardware RAIDs can be useful in some situations because they automagically handle certain situations like hot-plugging (including rebuilding) and reporting (audio-visual signs). c) "Hardware" RAIDs might not be DAS but also iSCSI or fibre channel, in which case it's useless and harmful (to performance) to do software RAID on them. Both hardware and software RAIDs have their uses, but the issue in this thread is to discover which component (if any) has a bug that makes the original configuration tried by the OP unusable. --------------enigD51114565ECD1AD185CFEE0D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHXx4JldnAQVacBcgRAkoKAJ9s49lvxsYu9sUu2RywRwcx3chjkQCfQsDS kCEiuAhKf9TNJU4rEGERMDs= =thrk -----END PGP SIGNATURE----- --------------enigD51114565ECD1AD185CFEE0D--
