Can’t create new DTQ
A DTQ cannot be defined for existing regular directories. A DTQ must be created
using StorEdge administration interfaces (telnet, GUI or command-line), which
automatically creates a new directory as part of the DTQ setup.
The maximum number of DTQs per volume is 255. If creation of the 256th DTQ on a
volume is attempted, the DTQ will not be created, and an error will appear in the
system log.
Nested DTQs are supported. This means that a DTQ can be created as a sub-
directory of an existing DTQ. The sub directory DTQ must be created from the
command line, using the dtq create command.
If an existing DTQ is moved under another DTQ, the moved DTQ will be converted
to a regular directory object and its quota record will be removed. The containing
DTQ will take account of the moved objects.
Hard links can be created only inside the same DTQ. Creating a hard link between
different DTQs is not allowed. There is no limitation for soft (symbolic) links.
Files moved from DTQ to another directory get new time stamps
and copy more slowly.
When moving objects into a DTQ, out of a DTQ or between different DTQs, but still
within a single file system volume, the operation is treated as if the object had been
moved from one volume to another. The StorEdge will perform a copy & delete
operation rather than a rename operation. This takes much more time.
