No, it hits both. Fortunately, quotacheck is run in parallel on the
MDT and the OSTs, that's why it scales well.
ah ok. thanks
That sounds to me like it is only hitting the MDT and not the OSTs.
which would mean if you have a lustre system that has been upgraded from
an older version, most of the file sizes reported on the MDT will be
zero and this must affect the validity of the quotacheck...

We've had problems with suse in the past. These were avoided by creating
/etc/rc.d/after.local containing:
modprobe lustre
mount -a
not pretty, but effective.

Hi Prasad，
I'm not a SuSe user but I think it's because your system is trying to

anyone have views on whether this sort of caching would be useful for
the MDT? My feeling is that MDT reads are probably pretty random but
writes might benefit...?

One thing to watch out for in your kernel configs is to make sure that:

I hope this is not the case for the now obsolete:

I get lots of these errors when using Lustre with a preempt kernel.
Earlier discussions on this list suggested that preempt should work even
tho it used to be blocked during the build process.
This is with freshly compiled 1.8.2 patchless clients, vanilla 2.6.27.39
kernel on OpenSuse 10.3. The
We had an LBUG on our MDS (on 15th Feb) and so attempted a failover to
the 2nd MGS/MDS server. This mounted the MGT fine but hung while
mounting the MDT (longer than 5 minutes).
To resolve the problem I unmounted the MGT and the MDT on a freshly
booted MDS/MGS and mounted the MDT as ldiskfs.
