I do create with missing sdd. Than i mount -a and get :"
mount -a
"mount: wrong fs type, bad option, bad superblock on /dev/md2,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so"
And
"EXT4-fs (md2): bad geometry: block count 3651722880 exceeds size of device (3651721600 blocks)" and the mount fails

Ok is the superblock on sdf4 bad? What can i do next?
thx
