NFS not working with block storage
I'm running a setup for my application with 3 app servers, one of which has a block storage volume mounted to it. For my application to run properly, I had to set up NFS and open that volume to the other 2 droplets. I followed one of Digital Oceam tutorials on how to set up NFS, and everything worked fine for about 1 day. After that, whenever I try to do anything related to mounted drive on the "client" droplet, the command just hangs. For example, if I just do "df -h" to see all the drives, including mounted ones, the command just hangs.
Thanks in advance for any suggestions!
