+### Please describe the problem.
+
+Identically configured remotes behave differently in the "git annex push" command after "git annex sync" to only one of them.
+
+### What steps will reproduce the problem?
+
+I have a repository on Linux and two USB backup sticks, all Ext4 file system. At one point I accidentally did "git annex sync music-backup-one".
+
+When I now "git annex push music-backup-two" it works as expected and I see the correct files on the stick and "git annex list" shows the content correctly. This is not true for "git annex push music-backup-one" as I must also issue "git annex mirror . --to=music-backup-one" for the content and "git annex list" to be correct (both commands are required in either order).
+
+How do I diagnose the problem so push works without the need for mirror on music-backup-one?
+
+During my investigation, I noticed the filemode (executable) bit for annexed files is not transferred to either USB drive if that is the only change (perhaps a separate issue).
+
