Description

ost-pools test_23b fails for RHEL 8.3 server/clients.

Looking at the suite_log for the failure at https://testing.whamcloud.com/test_sets/8445d81a-2e35-493c-bcf7-311524a97aa5, this is the first time we’ve seen ost-pools test_23b fail with

[4 iteration] dd: closing output file '/mnt/lustre/d23b.ost-pools/dir/f23b.ost-pools-quota4': Input/output error
total written: 20971520
stime=1607360253, etime=1607360637, elapsed=384
 ost-pools test_23b: @@@@@@ FAIL: dd did not fail with ENOSPC 
  Trace dump:
  = /usr/lib64/lustre/tests/test-framework.sh:6257:error()
  = /usr/lib64/lustre/tests/ost-pools.sh:1360:test_23b()

We have seen this test fail with the same error message, see LU-10396, and with “write error ... Input/output error“, but this is the first time we see dd fail with “close ... Input/output error”. From the value after total written, it looks like dd did fail, just not with “No space left on device" as the test requires/is looking for.

In the client1 (vm) dmesg log, we see
