Orvar, Two choices are described below, where safety is the priority. I prefer the first one (A).
Cindy A. Replace each 500GB disk in the existing pool with a 1 TB drive. Then, add the 5th 1TB drive as a spare. Depending on the Solaris release you are running, you might need to export/import the pool to see the expanded capacity (as a step 8) due to an existing bug. 1. Physically connect the new disks. 2. Replace the first disk. # zpool replace pool 500GB-1 1TB-1 3. Let resilver complete, then scrub. # zpool scrub pool 4. Replace the second disk. # zpool replace pool 500GB-2 1TB-2 5. Let resilver complete, then scrub. # zpool scrub pool 6. Repeat steps 2-5 until 4 disks are replaced. 7. Add 1TB-5 as a spare: # zpool add pool spare 1TB-5 B. Use zfs send/receive to copy ZFS datasets to new pool. 1. Physically connect the new disks. 2. Create the new pool with new disks. 3. Use zfs send/receive to copy ZFS datasets from old pool to new pool. 4. Make sure all data is available in the new pool between each zfs send/receive operation. Don't destroy the old pool until all data is verified. Orvar Korvar wrote: > I have a ZFS raid with 4 samsung 500GB disks. I now want 5 drives samsung 1TB > instead.

(Does cp warn if there was any error?) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
