Hi, Bernd,
I did all the instructions as
http://www.pci.uni-heidelberg.de/tc/usr/bernd/downloads/lustre/1.6/Readme.install
described.
Everything is fine, but when I created lustre FS on MDS, I got the error
messages:
mkfs.lustre --fsname=spfs --mdt --mgs /dev/hdb
Permanent disk data:
Target: spfs-MDTffff
Index: unassigned
Lustre FS: spfs
Mount type: ldiskfs

512 -q -O dir_index -F /dev/hdb
mkfs.lustre: Unable to mount /dev/hdb: No such device
Is the ldiskfs module available?
mkfs.lustre FATAL: failed to write local files
mkfs.lustre: exiting with 19 (No such device)
-------------------------------------------------
I am using a linux-source-2.6.20 which is patched by ubuntu, not from
www.kernel.org. Of course, I made some modifications on the lustre-patched
files(vfs_intend-2.6.20 & vfs_nointend-2.6.20) you released.
When I using modprobe to check the ldiskfs module, it says "FATAL : Module
ldiskfs not found." How should install the ldiskfs module?
Any responses will be appreciated.
Chris

Bernd,
I have downloaded the file you suggested for 2.6.20+ and I am at a
stand still with the following issues:
1. After patching the 2.6.20 vanilla kernel and configuring lustre: ./
configure --disable-liblustre --disable-tests and then running I make
I recieve:
make[3]: Entering directory `/usr/src/linux-2.6.20'
CC [M] /root/lustre-1.6.0.1-rc1-ql6/lnet/libcfs/linux/linux-proc.o

interesting with gcc-3.4 this works, whats your compiler version? I was
from
the very beginning a bit sceptical if its legal first to declare a
variable
as extern and then again static. Anyway you can safely remove the entire
line
65, it was only required for a previous version of the
2.6.21-sysctl.patch.
Its good your compiler complained about it, so I can remove this useless
forgotten line :)
I tried patching against 2.6.22 but I received some errors in the
quilt push -av process which I will post later. Additionally the
configure process complains about not having a definition for 2.6.22
in "lustre/autoconf/lustre-core.m4"
Well, 2.6.22 was only released today and I only did run a very very basic
test
if it works at all. If you want to try it, you will need mercurial and
need
to run "hg qpush -af" before running configure. The 2.6.22 patches so far
do
not have any version tests, so applying them and using a kernel <2.6.22
won't
work, thus I didn't apply them to -rc1.
The configure script also still doesn't know about 2.6.22, so you need to
compile with "make LDISKFS_SERIES=2.6.21-vanilla.series ...".
Cheers,
Bernd
