hi!
I tried to build lustre-1.6.4.2 in my system, but the following error occured,
/home/bharat/Desktop/lustre-1.6/lustre-1.6.4.2/lustre/lvfs/lvfs_linux.c:345: error: too few arguments to function ‘vfs_rename’
make[6]: *** [/home/bharat/Desktop/lustre-1.6/lustre-1.6.4.2/lustre/lvfs/lvfs_linux.o] Error 1
make[5]: *** [/home/bharat/Desktop/lustre-1.6/lustre-1.6.4.2/lustre/lvfs] Error 2
make[4]: *** [/home/bharat/Desktop/lustre-1.6/lustre-1.6.4.2/lustre] Error 2
make[3]: *** [_module_/home/bharat/Desktop/lustre-1.6/lustre-1.6.4.2] Error 2
make[3]: Leaving directory `/usr/src/linux-headers-2.6.22-14-generic'

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/bharat/Desktop/lustre-1.6/lustre-1.6.4.2'
make: *** [all] Error 2
my kernel version is 2.6.22.14.
and I configured patchless client in my system using the following command
[lustre]$ ./configure --with-linux=/unpatched/kernel/source
and after that I tried to build, using make then the above error occured.
can anyone help me in how to proceed building the patchless client for lustre.
Thanks and Regards,
Ashok Bharat

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

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