Hi,
I quite new on GlusterFS
Since the arbiter does not hold any data, how to choose it's size
compared to the other 2 bricks?
Regards
It depends on the maximum number of inodes (`df -i` ) any of the other
2 normal bricks can hold. The recommended inode size is 512 bytes but
since we store various gluster xattrs and possibly application's xattrs
on the file, I think 8KB per file is a good estimate. So "8KB x max. no.
of inodes " should be good for the worst case. If you have some idea of
the max. number of files you would actually be filling the bricks with,
that multiplied by 8KB works too as a practical estimate.
I hope I've not made any oversight in these calculations.
