nfsroot use

[estrim]

Hi,

 

I'm a Unraid noob but have been using NFS for 20 odd years, my use case is a couple of Raspberry PI's utilising NFS root filesystems (ie. network boot) which I'm moving from some QNAP's over to Unraid.

 

Whilst booting over NFS is working as expected, I am having a hard time keeping these up for more than a couple of hours, as I/O type errors get logged on the RPI's.

 

I am therefore keen to hear if anyone else is using nfs root successfully, and if so what export and root mount options worked for you.

 

With some playing & reading I've,

• Disabled hardlinking to avoid the stale NFS handle issues
• Disabled my cache drive on the share to avoid what I can from a inode-move-perspective
• Export settings wise I've played with combinations of sec=sys,rw,no_root_squash,insecure,no_subtree_check,async & sync
• On the RPI side I've played with: udp,vers=3,lock, nolock, wsize&rsize's 

 

Appreciate any pointers!
