<P><FONT SIZE=2>I need step by step procedure of building patchless client for lustre file system.I referred wiki.lustre.org. But I have a doubt,For bulding patchless client, Is it required to patch and build kernel source first as given in wiki and then configure using<BR>
[lustre]$ ./configure --with-linux=/unpatched/kernel/source<BR>
or not?<BR>
I have kernel version vanilla 2.6.22.14 and I'm trying to install lustre 1.6.4.2<BR>

<BR>
The default for Lustre is to _not_ support cluster-coherent flock locking,<BR>
because it can cause problems in some cases (depending on locking mode).<BR>
<BR>
There are client mount options "-o localflock" which just pretends that flock<BR>
locking is working (it is using only the local node's flock locking), and<BR>
"-o flock" which enables real filesystem-wide flock. You can pick between<BR>
the two, depending if you need real flock or not.<BR>
<BR>
Also, there have been improvements for the Lustre ADIO driver done at ORNL.<BR>
<BR>

<BR>
You should be able to build a "patchless" lustre client for kernels ><BR>
2.6.16, though I'm not sure if we have all of the kernel API changes<BR>
for > 2.6.22 in the Lustre code. The issue is that even though Lustre<BR>
clients no longer require kernel patches, the kernel APIs change without<BR>
notice or documentation, so there is always _something_ broken when a<BR>
new kernel is released.<BR>
<BR>
Could you also elaborate on the "1.6.4.* compatibility issue"? There<BR>
shouldn't be any compatibility problems between 1.6 releases, though<BR>
the current b1_6 development branch has a feature (adaptive timeouts)<BR>
which is likely to be removed before the final release. I would suggest<BR>
getting the specific Lustre release you want by CVS tag (v1_6_4_3 probably)<BR>
instead of the CVS tip.<BR>

The discrepancies between lfs df -h and df -h I think that largely <BR>
have to do with the way GB are calculated. Ether based on 1000 or <BR>
1024. Remember you lose about 5% of each underlying volume due to the <BR>
5% reserved for root.<BR>

What the group upcall does is get all the secondary groups for the<BR>
client user. There isn't enough room in the LNET message to send them<BR>
all, so the MDS has to look it up in the /etc/groups. If you don't care<BR>
about secondary groups at all, there is no harm in clearing the<BR>
group_upcall param.<BR>
<BR>
In theory, there also shouldn't be any harm in having different passwd<BR>
and group files on the MDS and OSSes than on the clients. It's highly<BR>
important, however, that all the clients have the same passwd and groups<BR>
files. Otherwise the clients could interpret the same UID as different<BR>
users, and people could go mucking around in each others files.<BR>
