The following command can be used to find out the free space available in a Slice/Mirror.

metarecover -n -v < Slice/Mirror > –p

Example:

Suppose the slice c1t0d0s6 is of size 40GB, and there are some soft partition exists on the same. So to find out the free space available in the slice, the following command can be used.

bash-2.05# metarecover -v -n c1t0d0s6 -p | more

Here the free space is 37753596 blocks. So almost 18GB free space is available.

Note: The slice name can be replaced with the mirror name to find the free space in the mirror.
