Re: [HPDD-discuss] Can't Mount MDT on MDS/MGS server

Do the mount or df commands show the MDT as mounted? If so, this error can be ignored, I think, as a side-effect of not having any OSTs connected to the file system. For first time mounts, you have to mount the MGT and MDTs before the OSTs, but you get this side-effect. Malcolm.

I currently have 3 VM's each running CentOS 6.5. I have 3 nic in each box, with eth0 being used for ssh and eth1 and 2 being teamed under bond0. I want all LNET communication going through the bond0 interface. My lustre.conf: # cat /etc/modprobe.d/lustre.conf) options lnet networks=tcp0(bond0) I have disabled iptables, selinux, etc. I can load and start lnet. I can ping each machine's bonded interface using normal ping  so I know the networking is fine. Right now the MDS is the only server on. # lctl ping 100.100.100.10@tcp0 12345-0@lo 12345-100.100.100.10@tcp When I try to mount the MDT, I get this error: # mount -t lustre /dev/sdb /mnt/mdt LustreError: 11-0: <fsname>-MDT0000-lwp-MDT0000: Communicating with 0@lo, operation mds_connect failed with -11 Any help would be appreciated. Thank You, -Konstantin
