Another thing I noticed is that it seems impossible to hotadd to a raid with persistent superblock with bitmap support. If you do the test case from the FR1 readme (mkraid -> raidsetfaulty -> raidhotadd) you get: kernel: md: syncing RAID array md0 kernel: md: minimum _guaranteed_ reconstruction speed: 2147483647 KB/sec/disc. kernel: md: using maximum available idle IO bandwith (but not more than 2147483647 KB/sec) for reconstruction. kernel: md: using 124k window, over a total of 25679808 blocks. kernel: md0: removed bitmap e605bc80 and following a complete resync. Is this intended behaviour? Regards, Stephan
