I have machine that had 2x 1TB drives in it. They were in the same zpool and that entire zpool is set to "copies=2". From what I understand this will store all my data twice, and if the SPA is doing its job right it will store the copies on different disks and store the checksum for any given block on the other disk.
I filled this with data. So I added a 1.5 TB drive to the pool. Where will my ditto blocks and checksums go? Will it migrate data from the other drives automatically? Will it migrate data if I scrub or re-silver? will it never migrate data and just store all the new blocks and checksums on the new drive? I am interested in making sure that a single drive failure will not cause loss of data, what should I do if anything? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
