Re: [MooseFS-Users] Total space calculation

[Ricardo J. B. <ric...@do...>]

I believe MFS info (the CGI) shows you total space, not usable space, so in 
your case it would show ~30 TB.

I have 2 small clusters, 2 chunkservers per cluster, 4 x 1TB disks per 
chunkserver and MFS shows me 7.2 TB total for each cluster.

I have goal=2 so I know I have ~3.5 TB usable, but since you can mix (i.e. 
have some dirs with different goal if you have more than 2 chunkservers) I 
guess it's hard to estimate usable diskspace from th CGI.

Cheers,
