root-6.24.2-1.el8 rebuild on mock on tmpfs one test fails

[bleve]

I tried to rebuild epel8 testing version of root and it failed one test case (three times so this is not just random failure).

150/1107 Test #109: gtest-io-io-test-RIoUring ...........................................***Failed 0.58 sec
Running main() from gtest_main.cc
Note: Google Test filter = -RCsvDS.Remote:RRawFile.Remote:RSqliteDS.Davix

Looks like this test is not proper.

No problem with previous versions so this is new failure.

Hi @bleve ,
the test does not fail in our builds, how can we replicate the issue on our side?

[bleve]

Have you tried to build on tmpfs?

[jblomer]

EL8 is tricky: there is a liburing but the kernel doesn't enable uring. Does it work if you build with cmake -During=off?

[bleve]

Disabling uring works. So problem is just epel - It must disable uring support for epel8 because kernel doesn't have support. Thank you I Add this information to epel8 bug report.
