Currently, no. If you haven't filled the pool more than 1 disk worth, you can juggle the data around.. * Create a new pool with just one disk, copy everything over (either via zfs send+recv or just plain copy). * Create a 4 disk raidz1 with one disk missing: * mkfile -n 250g /tmp/blah (if the disks are 250g) * zpool create pool_nas raidz1 c3d0 c3d1 c4d0 /tmp/blah * fail the /tmp/blah device * copy everything back * destroy temporary 1-disk pool * replace /tmp/blah with the single disk in the new pool /Tomas -- Tomas Ögren, st...@acc.umu.se, http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
