Warning: You are attempting to increase the number of bits used for NFSv3
         FSIDs and File IDs from 32 to 64 on Vserver "vs0". This could
         result in older client software no longer working with the volumes
         owned by Vserver "vs0".
Do you want to continue? {y|n}: y

Warning: Based on the changes you are making to the NFS server on Vserver
         "vs0", it is highly recommended that you remount all NFSv3 clients
         connected to it after the command completes.
