<br>
We have one of our Lustre filesystems that we export via NFS to a <br>
machine that we don't currently have the Lustre client modules built for.<br>
<br>
The remote machine can mount the filesystems however as soon as it tries <br>
to access a file on the NFS mounted filesystem, it causes the NFS server <br>
to crash and reboot.<br>
<br>
The NFS server is Ubuntu 12.04LTS x86_64, kernel 3.8.0-27-generic, and <br>
Lustre version :<br>
<br>
Lustre: Build Version: v2_4_90_0-g3917e62-CHANGED-3.8.0-27-generic<br>
<br>
This was checked out from git yesterday, so is the newest 2.4 code.<br>
<br>
The filesystems are exported as :<br>
<br>
/home 192.168.0.0/24(rw,async,no_subtree_check)<br>
<br>
On the target system I did the following :<br>
<br>
mount test1:/home /mnt<br>
ls /mnt<br>
<br>
At this point it crashes the server, the relevant section of the <br>
crashlog as captured from the console is :<br>
<br>
[ 472.439409] LustreError: <br>
2131:0:(llite_internal.h:1175:ll_inode2fid()) ASSERTION( inode != ((void <br>
*)0) ) failed:<br>
[ 472.449660] LustreError: <br>
2131:0:(llite_internal.h:1175:ll_inode2fid()) LBUG<br>
[ 472.478560] Kernel panic - not syncing: LBUG<br>
<br>
Does anyone know how I can fix this ?<br>
<br>
Cheers.<br>
<br>
Phill.<br>
