Hi,

A few weeks ago i have noticed one client failing with that kind of message all over dmesg:

[1291431.185694] LustreError: 1787:0:(client.c:571:ptlrpc_check_status()) @@@ type == PTL_RPC_MSG_ERR, err == -116 [EMAIL PROTECTED] x10138718/t0 o35->[EMAIL PROTECTED]@tcp:12 lens 296/392 ref 1 fl Rpc:R/0/0 rc 0/-116 [1291431.244792] LustreError: 1787:0:(client.c:571:ptlrpc_check_status()) Skipped 5 previous similar messages [1291431.273685] LustreError: 1787:0:(file.c:97:ll_close_inode_openhandle()) inode 3546284 mdc close failed: rc = -116 [1291431.304907] LustreError: 1787:0:(file.c:97:ll_close_inode_openhandle()) Skipped 5 previous similar messages

and server:

[1288626.454813] LustreError: 3624:0:(mds_open.c:1461:mds_close()) @@@ no handle for file close ino 3546284: cookie 0xddc618f5ff56c7b6 [EMAIL PROTECTED] x10138718/t0 o35->[EMAIL PROTECTED]:-1 lens 296/392 ref 0 fl Interpret:/0/0 rc 0/0 [1288626.454827] LustreError: 3624:0:(mds_open.c:1461:mds_close()) Skipped 9 previous similar messages [1288626.454842] LustreError: 3624:0:(ldlm_lib.c:1349:target_send_reply_msg()) @@@ processing error (-116) [EMAIL PROTECTED] x10138718/t0 o35->[EMAIL PROTECTED]:-1 lens 296/392 ref 0 fl Interpret:/0/0 rc -116/0 [1288626.454852] LustreError: 3624:0:(ldlm_lib.c:1349:target_send_reply_msg()) Skipped 9 previous similar messages

Both still running beta7, didnt tried 1.6.1 yet and out of total 3 clients it's happening only on one of them evry time same one, even if i access same files on other clients they run ok witn no such problems.
Any thoughts on what it is ?


Another question is, can i switch to Lustre 1.6.1 from beta7 without problems ?
