I alway use my 219 with only a single disk configuration 1,5TB seagate sata disk with 3.6.1 Build 0302T. Yesterday a bought a identicality drive (same manufactor,size and firmware) and then I started the migration to RAID1 configuration. After 4hours the nas restarted and started to blinking red. Here the log:

A cat of /proc/mdstat give me that the main partition was degraded! I remove the drive from configuration but now I can't retry to build a RAID1 with the same drive. Is possibile to find more detailed log about what is failed during the creation? Thanks
