I've come across an interesting quirk in the lustre startup script (/etc/init.d/lustre) when using zfs as the back end filesystem... When I try to mount lustre using the service command I get the following error... :~]# sudo service lustre start Mounting lustre-ost0/ost0 on /ost0/lustre2-OST0000 mount.lustre: /lustre-ost0/ost0 has not been formatted with mkfs.lustre or the backend filesystem type is not supported by this tool But it works without complaint if I run the mount script directly... ~]# /etc/init.d/lustre start Mounting lustre-ost0/ost0 on /ost0/lustre2-OST0000 ~]# df | grep lustre lustre-ost0/ost0 105825194240 3456 105825188736 1% /ost0/lustre2-OST0000 Has anyone else seen this?
