Hi guys, thanks for your help getting me going with this over the last week. I kicked it off last night and all is well.
The only Q i have is it seems to be abit slow? When i kicked it off it insisted that i give a backup file --backup-file that i set to /root/backupfile and now the reshape seems to be constantly accessing my md3 as well as the md4 (the one that is being reshaped) i have set the min and max that is used when i am rebuilding the array/testing
cat /sys/block/md4/md/sync_speed_min
200000 (local)
cat /sys/block/md4/md/sync_speed_max
7168000 (local)
but still the speed is abit slow?
md4 : active raid6 sdg1[4] sdf1[0] sde1[1] sdd1[2] sdc1[5] sdb1[3] sda1[6]

As you can see lots of write access to md3 and low level read/write to the constituent drives of md4
Does this seem ok? or is it slow (like i suspect!)
