I have 2 servers. I crash one server1 and then write data on the mount say /mnt/ext/a.txt. Now I bring up server 1 and then do ls -alR /mnt/ext or even cat /mnt/ext. Even after running those commands I see that the contents of file on server1 are still old. It doesn't change until I do an update on /mnt/ext/a.txt, at that point it changes (which we know why). Could someone please tell me what am I doing wrong? Why is self healing not working?
