Request to enhance the functionality of "lfs setdirstripe" to include the selection of specific MDT's as appose to a series.
The current implementation allows for stripe on a series of MDT's, e.g.:
This will stripe to 4 MDT's at the start index of MDT0.
I am proposing we enhance this to stripe to multiple specific MDT's, e.g.:
This will stripe to 4 specific MDT's with the indexes 1, 3, 5 & 7 - in which case no start index would be required.
This will allow for more controllable striping in a case where a file system could have many MDT's across many systems and in cases where multiple MDT's may exist on one server.
