DNE3: enhance "lfs mkdir" to select specific MDTs

XMLWordPrintable

    • 9223372036854775807

      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.:

      lfs setdirstripe -D -i 0 -c 4 /some/dir
      

      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.:

      lfs setdirstripe -D -o 1,3,5,7 /some/dir
      

      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.
