Volume /acct is in use by NFS global service 'www.wwmed.com'.
Volume /acct in namespace wwmed is in use or being browsed by global services.
Migrating metadata for this volume will disrupt clients using these services.
No other volume will be affected by this procedure.
Proceed with metadata migration? [yes/no] yes

The CLI prompts for confirmation before it starts the migration; enter yes to proceed.
The nsck utility copies all of the metadata to the target share, verifies its integrity at
the target share, then switches the managed volume over to the new metadata share. If
the migration fails in any way before the last step, the volume comes back online with
its metadata still on the original share. You must manually restart the migration after a
cancellation or unexpected failure.
As with all nsck jobs, this operation produces a report to show its progress. The CLI
shows the report name after you invoke the command. Use
of nsck reports, and use
source and target shares, the size of the metadata, and the time required to migrate it.
For example, this command sequence migrates metadata for the wwmed~/acct
volume and then shows the report:
wwmed
/acct
nas1(192.168.25.21): /vol/vol1/meta1 (nfs3)
