Hi
The ID in the EMS message can be translated with "volume show-inode -volume <vol name> -inode <number>" command.
i'm not aware of NetApp way to show number of files. and the exact number dosen't matter in relation to this error. it's the size of the index that do (also something i'm not sure how to get).
You can get prey fast file count on a folder with the NetApp migration tool (XCP).
