NAME
zvol_wait — wait for ZFS volume links to appear in /dev
SYNOPSIS
zvol_wait
DESCRIPTION
When a ZFS pool is imported, the volumes within it will appear as block devices. As they’re registered, udev (7) asynchronously creates symlinks under /dev/zvol using the volumes’ names. zvol_wait will wait for all those symlinks to be created before exiting.
