Absolutely no problem. Just be aware that if *any* of your devices fail, all is lost. (Because you've said it's configured as a nonredundant stripe.) Also, one of the best features of ZFS is automatic checksumming. I love that demonstration where they create a raid set, shutdown, insert the disks into some other system, and start writing random bytes to random sectors ... Put the disks back into the first system and bring it all up. No data errors, because they were detected and corrected. Unfortunately, in a nonredundant configuration, you can only detect errors. Not correct them. So the arguments in favor of adding some redundancy are pretty compelling for all but the most worthless data. In your case, you would only need to add one more disk ... 3x 1.5T disks in a raidz set ... total 3T usable, and 1 disk redundancy. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
