Description

This issue was created by maloo for Andreas Dilger <[e-mail]>

This issue relates to the following test suite run: https://testing.hpdd.intel.com/test_sets/c7f684c6-2a8e-11e6-acf3-5254006e85c2.

This has failed quite a number of times, but was overshadowed by LU-8279 also causing a large number of sanity-sec failures.

The sub-test test_16 failed with the following error:

mgs and c0 idmap mismatch, 10 attempts

It looks like the OST rebooted for some reason, since the modules are not loaded and the dmesg log is empty:

trevis-54vm8: opening /dev/lnet failed: No such device
trevis-54vm8: hint: the kernel modules may not be loaded
trevis-54vm8: IOC_LIBCFS_GET_NI error 19: No such device
/usr/lib64/lustre/tests/sanity-sec.sh: line 981: [: ==: unary operator expected

Info required for matching: sanity-sec 16
