How to efficiently get sizes of all files stored in Lustre?
Hello, I would like to efficiently get sizes of all files stored in Lustre filesystem. My first idea was to use Lester, the Lustre lister, and 1) obtain all FIDs of all files from MDT (lester -A fslist -a format=lustre -a show_fid MDT_DEVICE) 2) then scan all OSTs with the same command, 3) and finally match FIDs, and compute file sizes. Unfortunately, FIDs on MDT are different from FIDs on OSTs. Why is it so? Is there any way to get sizes of all files efficiently? -- Best regards, Marcin _______________________________________________ Lustre-discuss mailing list Lustre-discuss-aLEFhgZF4x6X6Mz3xDxJMA@public.gmane.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
