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

[Charles A. Taylor]

Hi Vincenzo,

We hit this too.   There is a bug about it in the lustre bugzilla.   You
can edit the script to fix it but you can also get around it by simply 

export LUSTRE_VERS=1.8.1

before your make.   With that defined, it skips right over the problem
with get_latest_mtime().
