Hi Nhan, I get the following results with your metadata sample (/dev/dm-29, /dev/dm-33 being sparse devices in my testbed with your metadata on): # dmraid -r /dev/dm-29: ddf1, ".ddf1_disks", GROUP, ok, 486326272 sectors, data@ 0 /dev/dm-33: ddf1, ".ddf1_disks", GROUP, ok, 486326272 sectors, data@ 0 # dmraid -tay ddf1_4c53492020202020808627c300000000346e1ff400000a28: 0 486326272 mirror core 2 131072 nosync 2 /dev/dm-29 0 /dev/dm-33 0 After activation: # dmraid -s *** Group superset .ddf1_disks --> Active Subset name : ddf1_4c53492020202020808627c300000000346e1ff400000a28 size : 486326272 stride : 128 type : mirror status : ok subsets: 0 devs : 2 spares : 0 The only device created is: brw-rw---- 1 root disk 253, 34 19.
