"By design" we will never get this totally in-sync, but currently we see
very very clearly how bad it can be if the servers first have to build
metadata before the files will be usable.
If ftp4 runs 10.0, it should be possible to use ionice to give higher io
priority to metadata building and lowest prio to ftp serving.
Good idea. I have started experimenting with ionice now...
But it seems to be a hazardous tool: any user is able to starve a system,
f.e. by doing "ionice -c1 -n0 bonnie...".
I guess ionice needs a mechanism like nice: a user can only lower the
priority, only root can raise.
This probably needs some more work: each process needs a default cfq class
and priority "somewhere in the middle" which is hard to define.
Cheers -e
