Look at the mounts right now
Run a few simple inspections and read the results directly; for example, execute these commands and compare their lines to see the source, type, and active options: ```$ sudo mount | grep nfs
nfs-server:/export on /mnt/nfs type nfs4 (rw,relatime,vers=4.1,proto=tcp,timeo=600,retrans=2)
$ findmnt -no SOURCE,TARGET,FSTYPE,OPTIONS /mnt/nfs
nfs-server:/export /mnt/nfs nfs4 rw,relatime,vers=4.1,proto=tcp,timeo=600,retrans=2
$ sudo nfsstat -m /mnt/nfs
/mnt/nfs from nfs-server:/export Flags: rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,proto=tcp,timeo=600,retrans=2,sec=sys```
Read the options and act
See concrete values: "rw" vs "ro" tells write permission, "vers=" shows NFS version, "proto=" selects TCP or UDP, "timeo" and "retrans" tune RPC retries, and "rsize"/"wsize" affect throughput; if the output shows unexpected options, remount with corrected settings or change fstab and reload the mount.
When the kernel tells a different story
Consult `/proc/mounts` for the kernel's view and `findmnt` for a structured display; sometimes automounters or systemd mount units add flags, so check the systemd unit or `/etc/fstab` if the live options differ from what you expect.
Tools worth using now
Use `mount` for a quick human view, `findmnt` to extract fields cleanly, and `nfsstat -m` for per-mount NFS diagnostics; combine those with `cat /proc/mounts` when you need the raw kernel line.
Wrap and move forward
Inspecting NFS mount options is fast and revealing: run the commands, interpret the key flags, and change the mount source where necessary; if he wants to master Linux storage and networking for certification, consider intensive exam prep such as CompTIA Linux+ or LPIC-1 with bitsandbytes.academy to turn these checks into confident skills.
