Linux can be equiped with CacheFS which is developed by David Howells. CacheFS is designed to operate on Network File System mounts and you will need to install the cachefilesd package which contains the CacheFiles userspace management daemon. The cachefilesd daemon manages the cached files and directories that are used by network filesystems such as NFS to perform persistent caching to a local disk.
NFS server /etc/exports
/home/nfs 192.168.1.11(rw,async,no_subtree_check,no_root_squash,no_all_squash)
NFS client /etc/rc.local
modprobe cachefiles
NFS client mount eg
/home/nfs -fstype=nfs,rw,noatime,fsc 192.168.1.10:/home/nfs
CacheFiles /etc/cachefilesd.conf
dir /home/fscache tag mycache brun 20% bcull 14% bstop 6% frun 20% fcull 14% fstop 6%
CacheFiles on tmpfs – CentOS 6.8 using tmpfs on /mnt/fscache and fscache on /home/fscache eg
#!/bin/sh mount | grep fscache || mount -t tmpfs -o size=2048m tmpfs /mnt/fscache ls /mnt/fscache/disk0 || dd if=/dev/zero of=/mnt/fscache/disk0 bs=1M count=2046 sleep 15 ls /mnt/fscache/disk0 && echo 'y' | mkfs.ext4 /mnt/fscache/disk0 mount /mnt/fscache/disk0 /home/fscache -t ext4 -o loop,user_xattr
… YMMV
