Aha! I think I've found the problem. It looks like the filesystem name on the OSTs is different than the MDT you are trying to use. On the MDT you have datafs and on the OSTs it looks like you have spfs. I'm guessing you wan the name "datafs" so you need to use tunefs.lustre to change the fs name on the OSTs. Here's how-- 1. Unmount the OSTs 2. Run "tunefs.lustre --fsname="datafs" /device/of/ost" for each of your OSTs 3. Mount everything back up and post the output of "lctl dl" on your OSSs and MDSs. -Aaron ps "lctl dl" is a quicker way of running cat /proc/fs/lustre/devices On Dec 30, 2007, at 4:00 AM, Albert Ozilov wrote: Hi Aaron, Thanks in advance for your help.

Hi! Could you post the IPs over your MDT/MGS, OSSs and Client? Also on the MDT/MGS I'm wondering if the MDT is in recovery. To check recovery status run-- cat /proc/fs/lustre/mds/datafs-MDT0000/recovery_status and post what you get back. Also you can do an lnet ping to the various points in your system. The syntax is "lctl ping nid" so to ping [EMAIL PROTECTED] the syntax would be "lctl ping [EMAIL PROTECTED]". Also post what you get back from that. -Aaron On Dec 29, 2007, at 7:29 PM, Albert Ozilov wrote: Hi, I am new user with Lustre file system, I am trying to run over Infiniband fabric (ofed 1.2.xxx), I am using Lustre version 1.6.4.1 I have created mgs/mdt on the same node and two OST's on different nodes, all looks fine till now.
