Hi!
Limit of 2TiB is for a single file. There is no limit for the total size of
all files in the system.
There is also no limit for number of files in the system. There are
installations with 100 million files.
RAM needed for the master server depends only on the number of files in
your system (not on their contents or size). Please have a look here:

Subject: [Moosefs-users] Hi, i have some doubts , please help me and answer
me
hi,i have some doubts ,please have a look as follows:
Some days ago, i asked the question that "About MooseFS, If the storage
500T, 3 million files, operating
500G times a day, how much memory the metadata needed? "
Your answer is:For 3 million files you need to insert just 4-8GB of RAM
into the master server.
However,today i see the FAQ about "
Does MooseFS have file size limit?
Currently MooseFS imposes a maximum file size limit of 2 TiB (2,199,023,255,
552 bytes). However we are considering removing this limitation in the near
future, at which point the maximum file size will reach the limits of the
operating system, which is currently 16EiB (18,446,744,073,709,551,616
bytes).
"
from the FAQ,such as "Currently MooseFS imposes a maximum file size limit
of 2 TiB (2,199,023,255,552 bytes),and so on."
i have some doubts,now i want to ask you some questions ，please answer
me :
problem one: About MooseFS,what size does it support the single file? and
what size about the total numbers of file??
problem two: As your answer"For 3 million files you need to insert just 4-
8GB of RAM into the master server. ",
wether it supports the situation "About MooseFS, if we insert just 4-8GB of
RAM into the master server,it'll support the storage 500T, 3 million files,
operating
500G times a day"??
That's all ,thanks a lot!
Sincerely look forward to your reply!
Best regards!
