Read man mdadm the section on "CREATE MODE", the last paragraph before the "General Management options" are listed. Be sure that you have mdadm 1.4.0 or later. NeilBrown [ the paragraph reads: When creating a RAID5 array, mdadm will automatically create a degraded array with an extra spare drive. This is because building the spare into a degraded array is in general faster than resyncing the parity on a non-degraded, but not clean, array. This feature can be over-ridden with the --force option. if you remove the "-I" that really shoudn't be there... :-( ] > > TIA > > -- > J.A.
