Hi,
I did a disk by disk replacement successfully for an existing Raid 5 array that had disk fail. Data is all present, and expanded from 4 x 3TB to 4 x 4TB.
However if I restart the NAS, I get an error and says RAID inactive on restart.
I can fix this by going to Storage Manager->Storage space → recover and once that completes all is well.
If I run MD_checker PRIOR to recover, this is result.
Welcome to MD superblock checker (v1.4) - have a nice day~

So seems to be something broken on boot. Any ideas what to start checking?
