Maybe I have not expressed myself clearly. I want to add the same data directory to multiple containers (bind mount). The data is stored in a zfs pool if this is relevant to my question.
Now, we presume there are two independant users (or services) working on two different containers. They are editing the same file on the common data storage at the same time. Can this corrupt my filesystem or is this managed by the host (or kernel or whatever) correctly? Could this be a problem and I damage my filesystem this way?
