Thank you! but I don't need to pass from Raid1 to Raid5...I need to create a Raid1 with 2 single HDD.
Anyway, I dont know if this is right but I'll explain what I did :
the first disk was on the system with file system and folders active and mounted
I connected the second one that was formatted in NTFS
I deleted the partition and then created the array Raid1 with single disk : mdadm --create /dev/md0 --level=1 --raid-devices=2 missing /dev/sdb1
Created the File system and rsync folders from old one to new one
unmount the partitions with unmount /dev/sda1 and unmount /dev/md0
Then i recreated the array with : mdadm /dev/md0 -a /dev/sda1
now I can see, in Raid Manager, that the array is recovering...I'm waiting.
Is this correct?
I notice that in File System I have something like this :
/dev/md0/ | Label : share | File System EXT4 | unmount
/dev/sda1/ | Label : HomeNas:0 | File System Linux_Raid_Member | unmount
is anything all right?
Thank you.
