[Lustre-community] Lustre client mount error

Hi there,

You really want to direct this conversation instead to lustre-discuss at
lists.lustre.org. There are several engineers who monitor that list and help
others out. This mailing list is for community planning related discussions.

Thanks,
Bojanic
