[Lustre-discuss] Vanilla 2.6.22.19 + Lustre 1.8.1: unable to open the tree_status file

[Vincenzo Spinoso]

Hi all,
we are currently using lustre 1.8.0.1 in production, using a Vanilla  
kernel 2.6.22.14.
No problems at all with the previous building, except for the new  
lustre 1.8.1.
I succeed in building the patched kernel and configuring lustre, but  
when running make rpms it build just
lustre-ldiskfs-3.0.9-2.6.22.19_200909021808.x86_64.rpm
lustre-ldiskfs-debuginfo-3.0.9-2.6.22.19_200909021808.x86_64.rpm
and then I get the following:

[...]

Now I've tried again the same procedure against lustre 1.8.0.1 with  
linux 2.6.22.19, and I've no problems.

The exception is on opening the "tree_status" file.  There is no  
"tree_status" in 1.8.0.1, while "lustre-1.8.1/tree_status" exists.
It seems that make cannot open it...  Can I simply move it somewhere  
else to solve the problem?

Thanks in advance!
