NAME

     zfs-wait — wait for activity in ZFS filesystem to stop

SYNOPSIS

     zfs wait [-t activity[,activity]…] filesystem

DESCRIPTION

     Waits until all background activity of the given types has ceased in the given filesystem.
     The activity could cease because it has completed or because the filesystem has been
     destroyed or unmounted.  If no activities are specified, the command waits until background
     activity of every type listed below has ceased.  If there is no activity of the given types
     in progress, the command returns immediately.

     These are the possible values for activity, along with what each one waits for:
           deleteq  The filesystem's internal delete queue to empty

     Note that the internal delete queue does not finish draining until all large files have had
     time to be fully destroyed and all open file handles to unlinked files are closed.
