Why doesn't the data on the disks match?

Question

Dell

Hello everyone, the essence of the question:
There is a Dell storage system that is connected to 2 Dell servers via SAS
, 3 disks are created, both servers see these disks (letters and disk names are the same on 2 servers), but when I upload any data from the 1st server to any from these disks, then this data is not on the 2nd server and vice versa, how can this be?

Answer 1

For shared drives, regular file systems are not meant to be. Most likely, as a result of simultaneous recording, you will lose data. In such cases, cluster file systems such as GFS2, OCFS2 are used.
