[LU-14321] Interop: sanityn test 106a fails with '/mnt/lustre/f106a.sanityn btime (0:1608796627) diff'

Thu, 7 Dec 2023 21:45:44 +0000

sanityn test_106a was added by patch 3f7853b31ef6 “~~LU-10934~~ llite: integrate statx() API with Lustre” to Lustre 2.13.53.242 on 27 MAY 2020. When we test Lustre clients >= 2.13.53.242 and Lustre servers < 2.13.53.242, this test will fail.

Looking at the suite_log for https://testing.whamcloud.com/test_sets/cd04c059-55e9-475b-88de-2cbef096f515, we see the error message

In addition, the same patch added a call to ‘lfs setstripe’ that is failing for the same Lustre client/server combinations. The code added is

3090 
3091         $LFS setstripe -E 1M -c 1 -E -1 --extension-size 64M $DIR1/$tfile ||
3092                 error "Create $DIR1/$tfile failed"
3093

with error

We need to skip sanityn test 106a for servers with Lustre version < 2.13.53.242.

For test 51b, should we just skip the ‘lfs setstripe’ for Lustre servers with version < 2.13.53.242?
