problem with executing file permissions

Asked by Marcin Jaciuk

We have two workstations with Ubuntu (Server) 18.04.5 LTS installed on them. Recently a CEPH storage was organised and it turned out that there is a problem with executing file permissions. Workstation local user_A can modify or remove files stored on CEPH, which benolg to local user_B, even though according to permissions he should not be allowed to. It is the same case for the files & directories stored on the additional local drives of those workstations which are mounted via fstab. We do not observe such a behavior in case of machines running on other distributions.

What would be the cause of this problem and more important the solution for it?

Check mount options on the storage. What file system are you using on the storage?
Can you please give the fstab line you are using to mount the device.
