Subject: [PATCH 2/6] iotests: Skip test 079 if it is not possible to create large files
Date: Tue, 19 Nov 2019 18:08:17 +0100	[thread overview]
Message-ID: <20191119170822.45649-3-thuth@redhat.com> (raw)
In-Reply-To: <20191119170822.45649-1-thuth@redhat.com>

Test 079 fails in the arm64, s390x and ppc64le LXD containers, which
apparently do not allow large files to be created. Test 079 tries to
create a 4G sparse file, so check first whether we can really create
such files before executing the test.
