[LU-11550] replay-single test 48 fails with 'client_up failed'

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Affects Version/s: Lustre 2.12.0
• Severity: 3

Description

replay-single test_48 fails. Looking at the client test_log from https://testing.whamcloud.com/test_sets/85c0633e-d2a1-11e8-b589-52540065bddc , we see

Started lustre-MDT0000
CMD: onyx-35vm8 lctl set_param fail_loc=0x80000216
fail_loc=0x80000216
 replay-single test_48: @@@@@@ FAIL: client_up failed 

The client_up() routine calls ‘lfs df’ on the mount point on the client node.

If we compare the console logs from this failed test to a replay-single test_48 that passes, we notice there is one LustreError line in the failed test. From the console log (vm6), we see the following line

08] LustreError: 6616:0:(client.c:1193:ptlrpc_import_delay_req()) @@@ req wrong generation:  req@ffff8b10e7beaa00 x1614621037646320/t0(0) o13->lustre-OST0005-osc-ffff8b10fbd7b800@10.2.8.61@tcp:7/4 lens 224/368 e 0 to 0 dl 0 ref 2 fl Rpc:W/0/ffffffff rc 0/-1

This test has only failed with the ‘client_up’ failure once this year.
