In OpenAFS, the fs listquota command relies upon

struct AFSFetchVolumeStatus {
    afs_int32 Vid;
    afs_int32 ParentId;
    char Online;
    char InService;
    char Blessed;
    char NeedsSalvage;
    afs_int32 Type;
    afs_int32 MinQuota;
    afs_int32 MaxQuota;
    afs_int32 BlocksInUse;
    afs_int32 PartBlocksAvail;
    afs_int32 PartMaxBlocks;
};

which cannot represent volume quota or partition details for partitions
larger than 2TB.   The values reported by the file server will be
truncated to fit.
