[Lustre-discuss] problems with llmount.sh

[Kristen J. Webb]

I've gotten lustre installed on CentOS 6.0 and
I'm now trying to run llmount.sh as the first test.

#./llmount.sh
Stopping clients: lustre64.nm.teradactyl.com /mnt/lustre (opts:)
Stopping clients: lustre64.nm.teradactyl.com /mnt/lustre2 (opts:)
Loading modules from /usr/lib64/lustre/tests/..

mkfs.lustre: Can't make configs dir /tmp/mntnWOAUh/CONFIGS (Permission denied)

mkfs.lustre FATAL: failed to write local files



I ran in sh -x mode to get the failing command

sh -c '/usr/sbin/mkfs.lustre --mgs --mdt --fsname=lustre --device-size=200000 
--param sys.timeout=20 --mountfsoptions=errors=remount-ro,user_xattr,acl --param 
lov.stripesize=1048576 --param lov.stripecount=0 --param 
mdt.identity_upcall=/usr/sbin/l_getidentity --backfstype ldiskfs --reformat 
/tmp/lustre-mdt1'

And then an strace to get more info:
....

Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 0 mounts or
0 days, whichever comes first.  Use tune2fs -c or -i to override.

# ls -l /dev/loop0
brw-rw----. 1 root disk 7, 0 Sep 29 17:28 /dev/loop0


Is the EACCES error related to the permissions on the loop0
device or is it something else?

The / filesytem on my test system is ext4 and I'm trying to do it all as root.

Also, I've done all of the server rpm installs.  Do I need to do
the client rpms as well?
