We've been running Lustre happily for a few months now, but we have one client that can be troublesome at times and it happens to be the most important client. Its our "file server" client as it runs NFS and Samba. I'm not sure where to start. I've seen this client disconnect from lustre nodes, but then recover and reconnect. There are hundreds of messages in dmesg about a few inodes. The big problem happened a few weeks ago when this client was booted and never could reconnect. The client and the lustre nodes simply kept saying HELLO to each other.
Anyways as of right now this is what I see in dmesg: nfsd: non-standard errno: -108 LustreError: 30558:0:(mdc_locks.c:646:mdc_enqueue()) ldlm_cli_enqueue: -108 LustreError: 30558:0:(mdc_locks.c:646:mdc_enqueue()) Skipped 2114 previous similar messages LustreError: 30558:0:(file.c:3280:ll_inode_revalidate_fini()) failure -108 inode 561619132 LustreError: 30558:0:(file.c:3280:ll_inode_revalidate_fini()) Skipped 777 previous similar messages LustreError: 29282:0:(file.c:116:ll_close_inode_openhandle()) inode 18382976 mdc close failed: rc = -108 nfsd: non-standard errno: -108 LustreError: 29282:0:(file.c:116:ll_close_inode_openhandle()) Skipped 17238 previous similar messages nfsd: non-standard errno: -108 nfsd: non-standard errno: -108 nfsd: non-standard errno: -108 nfsd: non-standard errno: -108 nfsd: non-standard errno: -108 LustreError: 29282:0:(client.c:858:ptlrpc_import_delay_req()) @@@ IMP_INVALID req@ffff81032da81800 x1360479978792199/t0 o35->[email protected]@tcp:23/10 lens 408/1128 e 0 to 1 dl 0 ref 1 fl Rpc:/0/0 rc 0/0 LustreError: 29282:0:(client.c:858:ptlrpc_import_delay_req()) Skipped 19011 previous similar messages nfsd: non-standard errno: -108 LustreError: 11-0: an error occurred while communicating with 192.168.5.104@tcp.

They gave us money and facilities, we didn't have to produce anything! You've never been out of college! You don't know what it's like out there! I've worked in the private sector. They expect results. -Ray Ghostbusters _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
