Re: [Moosefs-users] bug ?

[Sébastien M. <seb...@u-...>]

Hi Michal,

I read your faq about the usage of memory . But how to calculate the 
quantity of memory with the master informations following  ?

all inodes: 16782386
directory inodes: 577617
file inodes: 16204746
chunks: 2104855


I added  a lot of swap but it change nothing. It's normal ?
