Dear all,
I've got the following problem:
Whilst inserting the 5th hdd to my raid 6 with 4 devices something went wrong and it's not possible to reach the raid.
This is what I get from mdadm --Detail /dev/md127:
/dev/md127:

2 8 32 2 active sync /dev/sdc
3 8 48 3 active sync /dev/sdd
4 0 0 4 removed
5 8 80 - spare /dev/sdf
Then I tried to scan via mdadm --etail --scan
mdadm: cannot open /dev/md/Raid6TB: No such file or Directory
Can anyone give me a hint to find a solution for my problem?
I just want to remove raid device number 4 from the Array.
Thanks in advance,
