[Test][BUG] Add testcase to replace-brick and test self-heal of files
Testcase steps: 1.Create directory on mount point and write files/dirs 2.Create another set of files (1K files) 3.While creation of files/dirs are in progress Kill one brick 4.Remove the contents of the killed brick(simulating disk replacement) 5.When the IO's are still in progress, restart glusterd on the nodes where we simulated disk replacement to bring back bricks online 6.Start volume heal 7.Wait for IO's to complete 8.Verify whether the files are self-healed 9.Calculate arequals of the mount point and all the bricks CentOS-CI failure due to the following bug: https://bugzilla.redhat.com/show_bug.cgi?id=1807384 Change-Id: I9e9f58a16a7950fd7d6493cbb5c4f5483892851e Co-authored-by: Vitalii Koriakov <vkoriako@redhat.com> Signed-off-by: Vitalii Koriakov <vkoriako@redhat.com> Signed-off-by: kshithijiyer <kshithij.ki@gmail.com>
