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

Yes, I replaced my file system name with <fsname> in the email. -Konstantin From: Patrick Farrell [mailto:paf@cray.com] Sent: Friday, October 17, 2014 1:35 PM To: Konstantin Litovskiy; hpdd-discuss(a)lists.01.org Subject: Re: [HPDD-discuss] Can't Mount MDT on MDS/MGS server Konstantin, A quick thought: Did you deliberately remove your file system name and replace it with <fsname> in your email? Otherwise, you probably want to change the file system name in the format command and try again. I' think the '<' and '>' symbols may cause problems. (If not now, they probably will for some other software at some point.) - Patrick Farrell From: Konstantin Litovskiy <konstantin@baymicrosystems.com<mailto:konstantin@baymicrosystems.com>> Date: Friday, October 17, 2014 at 3:28 PM To: "hpdd-discuss@lists.01.org<mailto:hpdd-discuss@lists.01.org>" <hpdd-discuss@lists.01.org<mailto:hpdd-discuss@lists.01.org>> Subject: [HPDD-discuss] Can't Mount MDT on MDS/MGS server Hello, I am new to Lustre and am trying to setup a simple environment (1 of each Client, MDS, OSS) to test basic functionality and to familiarize myself with the installation procedures. 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<mailto:100.100.100.10@tcp0> 12345-0@lo 12345-100.100.100.10@tcp<mailto: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
