[ Please Cc me in the answer as I'm not in the list ] We have working mdadm RAID-10 (2 near, 32k chunks) with these drives: sda: 250G sdb: 250G sdc: 160G sdd: 160G Since we would like get more free space, so we need to change our 160G drives (sdc, sdd) to bigger one. Is there a way how to switch/change drive in RAID-10 without having RAID degraded for a while? I simply do not want manually fail any of these drives. Option --grow for mdadm is not working for RAID-10 (this is probably desirable feature). I wonder if there is anything different which we might give a try.
