pquota + xfs_fsr cron

Hello list,

Many of the posts here are DLEVEL, so I hope this won't seem too pedestrian.

My questions are:


1) do project quota's noticeably slow xfs down?

That might sound silly, but I'm planning to use them quite
extensively. Sure, initializing the quota can take a while (I don't
want to limit the depth), but aside from this can't find any ill
effects in the lab.


2) is it moronic to do a nightly xfs_fsr?

It seems reasonable that my system defrag XFS volumes automatically.

The problem is I often don't have access my machines (no SSH), so
would like to leave this simple option in place.

Sure I can write a little script to check the defrag % then act
accordingly, but xfs_fsr seems like it would already work.


3) Finally, according to the docs, unless instructed otherwise xfs_fsr
should check all XFS volumes present in mtab. My lab box only has one
volume, but supposing there were two (or more) should I expect it to
divide the 2 hours time it spends nightly between all mounted XFS
volumes?


Thanks in advance!
