We are trying to add a Windows Shared Folder as the repository location for a Single Node Elasticsearch Instance that is running on SUSE SLES.

However once we try to create a new snapshot we get the following error:

> [2018-12-10T11:00:36,436][WARN][r.suppressed] path: /\_snapshot/auto\_repo\_nov\_2018/test, params: {repository=auto\_repo\_nov\_2018, snapshot=test}

I think we might have made a mistake adding the windows Shared Folder in our linux server. What we did was the following steps:

1. Mount the Windows Shared Folder on linux with a command like the following in /etc/fstab by using command:

> \<windows server shared folder\> \<linux mount point\> cifs defaults,gid=,file\_mode=0777,dir\_mode=0777,noauto,nofail,credentials=\<credentials file\>,x-systemd.automount,x-systemd.requires=network-online.target 0 0

1. Add the mount point at **path.repo** inside our elasticsearch.yml.

2. Finally we just register the repository in Elasticsearch.

Do you have any idea what our problem is?.
