I have a question on a issue that follows us for years, and we have never stopped to think about how to fix.
We have many NFS clients using a NFS server for backup purposes. The clients runs cPanel, and we see that when the NFS server have some problem for any reason, like hardware failure, nfs service is down, network issue or whatever, it happens that the client cannot see the /backup anymore, and if you do a "df -h" the shell is stuck. Other issues are that we cannot create any account on cPanel, the server start to be loaded, Webmail crashes, etc.
My question is, how do I set the fstab on clients to mount the NFS partition in a way that anything that happens to the server, the partition is either unmounted or anything that could not affect the client OS ?
Thank you !
