Check var/log/messages and the lctl debug log:
lctl dk /tmpfile
The mount path looks like:
mount->mount.lustre->lustre_get_sb->lustre_fill_super

I'm making slow progress running Lustre OSS/OST in an embedded

embedded environment on a 'normal' x86 server.
Lustre 1.5.95 on Vanilla Kernel 2.6.18-3.
insmod of ldiskfs.ko complains about no version number for
posix_acl_from_xattr, but module seems to load ok.

However mount command fails with 'No such device' msg.
root@:/lib/modules/2.6.18-iop3.1tsPrivate/kernel/fs/lustre#
mount -t lustre /dev/sda /mnt/test/ost0
mount: Mounting /dev/sda on /mnt/test/ost0 failed: No such
device
The directory does exist:
root@:/lib/modules/2.6.18-iop3.1tsPrivate/kernel/fs/lustre# ls
/mnt/test/
ost0 sdTst
A grep through kernel and Lustre files give no references to "mount:" or
"Mounting" in source files.
Pointers on how to debug/where to look are appreciated.
