You're alluding to OSD replication problems, obviously assuming that one client would write to OSD A and the other client reading from OSD B. Which is not how Ceph works, but again, that's not your problem. > I have created an image on one client and mounted it on both 2 client I > have setup. > Details missing, but it's pretty obvious that you created a plain FS like Ext4 on that image. > When I write data on one client, I cannot access the data on another > client, what could be causing this issue? > This has cropped up here frequently, you're confusing replicated BLOCK storage like RBD or DRBD with shared file systems like NFS of CephFS. EXT4 and other normal FS can't do that and you just corrupted your FS on that image. So either use CephFS or run OCFS2/GFS2 on your shared image and clients.
