Hi all,
Thanks a lot for your time. I appreciate .
Immediate Feedback (with jet lag :) -
Roger,
I’ve already forced the —- assemble, just forget to write it , no more
mdadm --assemble --force /dev/md127 /dev/sdb /dev/sdc /dev/sdd /dev/sde
/dev/sdf /dev/sdg /dev/sdh
mdadm: /dev/md127 assembled from 5 drives - not enough to start the array.
I’ll move to raid6 , that was my 1st choice, but i didn’t build it
Phil,
Md0 .. I got the point, I will use it again to avoid mistakes
