[Moosefs-users] The implementation of append operation in MFS

[A.S. n. <a.s...@ho...>]

Dear all This is nagle, a new bie to MFS, I was wondering the implementation of append operation in MFS:Consider about this:1) A client want to create a very small file, then master allocates 64KB for it.2) The client writes so much for many times3) The size of file reaches the 64KB, but the client still wants to write much more, i name it as append operation.4) In this situation, the client may find that the space is used up, then it ask the master for much more space, then, what is going on?
Does any one give me a hint, thank you very much,Best regards,Nagle,
