The only one I know for sure is MFSMAXFILES, which represents the maximum number of files open at a time.
(reading a bit of code…)
MaxPacketSize seems to be part of the moosefs prococol. It represents the maximum size of a packet ;)
To be clearer, when a server talks « moosefs » to another, maxpacketsize represents the maximum length of
information send before trying to be decoded and understood by the receiver.
NODEHASHSIZE: a node seems to be recognised by a hash, and NODEHASHSIZE is the length of that hash.

Please remember I barely read the code, so I may be wrong !
