Show Suggested Answer

Suggested Answer: See explanation below.
1. vi /etc/auto.master
/mnt /etc /auto.misc --timeout=50
vi /etc/auto.misc
data -rw,soft,intr server1.example.com:/data
service autofs restart
chkconfig autofs on
When you mount the other filesystem, you should unmount the mounted filesystem, Automount feature of linux helps to mount at access time and after certain seconds, when user unaccess the mounted directory, automatically unmount the filesystem.
/etc/auto.master is the master configuration file for autofs service. When you start the service, it reads the mount point as defined in /etc/auto.master.

In RHEL8 and because de request is not with autofs, we can proceed in this way: # mount server1.example.com server:/data /mnt

One rule for the exam is that all changes we are making should survive reboot. Which is why autofs would be a good option.

Regarding the comments made in some posts=> which one to use static NFS mount (edit fstab) or autofs, well it is matter of preference but here points to keep in mind • It is RHCSA exam and it clearly emphasizes on autofs • Static NFS mount are manual and editing the fstab means prone to errors and hence there is good chance the system will NOT boot and also server1 where the share is hosted may be offline or network issue then you will need to go into emergency mode to repair that [reedit the fstab], even if boots will take long time to do so • You don’t need to create any directory on server2 using autofs, where as with static NFS mount you will need to create one like /mnt/Data etc in advance hence more effort involved, plus you need to set the correct permissions • Autofs onces configured correctly it works like Gem and hence Redhat emphasizing on it follow below

Server1 assume /data already share from server1.example.com, otherwise #echo '/data *(rw)' >> /etc/exports #exportfs -a Server2 #systemctl enable --now nfs-server #mkdir /mnt/shared #mount -t nfs server1.example.com:/data mnt/shared

At server1: # yum install -y nfs-utils # systemctl enable --now nfs-server # echo “/data server2(rw)” >> /etc/exports # exportfs -av At server2: #mount -o rw,sync server1.example.com:/data /mnt #df -h /mnt
