Hi, I have a strange requirement. My pool consists of 2 500GB disks in stripe which I am trying to convert into a RAIDZ setup without data loss but I have only two additional disks: 750GB and 1TB. So, here is what I thought:
1. Carve a 500GB slice (A) in 750GB and 2 500GB slices (B,C) in 1TB. 2. Create a RAIDZ pool out of these 3 slices. Performance will be bad because of seeks in the same disk for B and C but its just temporary. 3. zfs send | recv my current pool data into the new pool. 4. Destroy the current pool. 5. In the new pool, replace B with the 500GB disk freed by the destruction of the current pool. 6. Optionally, replace C with second 500GB to free up the 750GB completely. So, essentially I have slices out of 3 separate disks giving me my needed 1TB space. Additional 500GB on the 1TB drive can be used for scratch non-important data or may be even mirrored with a slice from 750GB disk. Will this work as I am hoping it should? Any potential gotchas? Thanks a bunch! -devsk -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
