From c494e34291d9f8cabe66afcb9616d78697b33df7 Mon Sep 17 00:00:00 2001 From: Ravishankar N Date: Mon, 21 Dec 2020 10:54:07 +0530 Subject: [Test] Check directory time stamps are healed during entry heal After an entry heal is complete, verify that the atime/mtime/ctime of the parent directory is same on all bricks of the replica. The test is run with features.ctime enabled as well as disabled.
