more useful output from mmrestripefs failures

It is possible, in a number of scenarios, to have a mmrestripefs operation fail when many disks are suspended and the filesystem is being restriped to bring the disks to the empty state.  This is not an uncommon operation, especially when data is migrated between ESS/SSS building blocks and snapshots are involved.  Failures occur even when data have been migrated to new disk pools or building blocks, leaving only immutable inodes associated with snapshots on the disks.

Rather than emit a generic "No Space left on device" error it would be nice if mmrestripefs would warn about the presence of snapshots, or other limiting factors, before running until failure.

    We want to make sure we understand your use case / question. Question from our development team:

    • When data migration is running out of space, what kind of more useful output are you expecting? Are you looking to understand situations where the active file system data are migrated successfully but running out of space on snapshot data migration?

    • If we were able to tell you there are remaining snapshot data migration, then how they you proceed with these kind of output? Simply force a deletion for the being deleted disks with snapshot deletion for their data migration are still pending?
