Hi All,

I am using mdadm 2.6.4 for managing RAIDs. I've a query like whenever i tried to add a new disk to a running linear array(JBOD)i get a message "cannot add new disk to this array"

The exact steps are as follows:
create a new array as:
mdadm -C /dev/md0 -llinear -n2 /dev/sata/ /dev/sata2

it is getting added and i am able to see with -D command.

Now add a new disk sata3 as follows:

mdadm --grow /dev/md0 --add /dev/sata3 I get the output as:

md: sdb has invalid sb, not importing!
md: md_import_device returned -22
mdadm: cannot add new disk to this array.

So my first doubt is whether mdadm 2.6.4 supports this features or not if it supports then do i need to change the driver?

Please help!
