[Lustre-discuss] Can someone help?

[Aaron Knister]

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 11.4.3.241 at o2ib the syntax would  
be "lctl ping 11.4.3.241 at o2ib". Also post what you get back from that.
