[Lustre-discuss] How to verify the Elan network using lctl
Hi, When I configure the lustre using lconf command, the command hangs. I can get the information in the dmesg. It shows "Can''t route to 0xac101a04: router error". I think the Elan is not enabled to the OST nodes. Does anybody know how to verify the Elan network (like ping in TCP/IP network) using lctl or other tools? Thanks in advance. ********************************************************** * Kevin Dong (???) * Tel:+86-10-58812310 Fax:+86-10-58812306 * Network Technology and Applications Research Laboratory * Computer Network Information Center * Chinese Academy of Sciences **********************************************************

[Lustre-discuss] How to verify the Elan network using lctl
As of Lustre 1.4.6 you can use the lctl ping command for any LNET-supported transport, e.g.: lctl ping 3@elan LNET must be running on both nodes (modprobe lnet; lctl network up) Make sure modprobe.conf is correct on both nodes (options lnet networks=elan) Kevin Dong wrote:>Hi, > >When I configure the lustre using lconf command, the command hangs.

[Lustre-discuss] How to verify the Elan network using lctl
Hi Nathaniel, I can''t find any files about LNET. Should I install the lustre source rpm packages? I just have installed the following packages in our systems: kernel-smp-2.4.21-32.0.1.EL_lustre.1.4.5.ia64.rpm lustre-1.4.5-2.4.21_32.0.1.EL_lustre.1.4.5smp.ia64.rpm lustre-modules-1.4.5-2.4.21_32.0.1.EL_lustre.1.4.5smp.ia64.rpm Thanks a lot. ********************************************************** * Kevin Dong (???) * Tel:+86-10-58812310 Fax:+86-10-58812306 * Network Technology and Applications Research Laboratory * Computer Network Information Center * Chinese Academy of Sciences ********************************************************** -----Original Message----- From: Nathaniel Rutman [mailto:nathan@clusterfs.com] Sent: Friday, June 02, 2006 12:35 AM To: Kevin Dong Cc: lustre-discuss@clusterfs.com Subject: Re: [Lustre-discuss] How to verify the Elan network using lctl As of Lustre 1.4.6 you can use the lctl ping command for any LNET-supported transport, e.g.: lctl ping 3@elan LNET must be running on both nodes (modprobe lnet; lctl network up) Make sure modprobe.conf is correct on both nodes (options lnet networks=elan) Kevin Dong wrote:>Hi, > >When I configure the lustre using lconf command, the command hangs.

I believe lnet first made it into 1.4.6. The rpms you quoted were 1.4.5. -David Vasil [The original message will be inserted by the server.] -----Original Message----- From: "Kevin Dong"<kevin@cnic.ac.cn> Sent: 6/1/06 9:04:01 PM To: "''Nathaniel Rutman''"<nathan@clusterfs.com> Cc: "lustre-discuss@clusterfs.com"<lustre-discuss@clusterfs.com> Subject: RE: [Lustre-discuss] How to verify the Elan network using lctl Hi Nathaniel, I can''t find any files about LNET.
