[Tiling] Re: inodes

[Frederic Junod]

Hello Gabriel,

We had the same issue on a ext3 partition; our first fix was to
rebuild the filesystem with more inodes.
It worked but we realized that the tiles directories where impossible
to manage: it took more than 2 days to get the dir size with 'du' and
rsync never finish (> 3 days to compute the files to transfer).
Now we're using amazon s3 to store all our tiles.

Maybe a distributed filesystem (like HDFS) can be an option ?

Regards,
fredj
