What does a connection timeout indicate when performing an NFS mount?
- by DeeDee
We have a shiny new QNAP NAS (TS-879U-RP), and I'm trying to mount it to our big ol' RHEL server in the same manner as our other two QNAP NAS devices. The IT department won't give me the root privileges to the NAS, so I can't SSH in (I know, I know). The first thing I did was to, via the QNAP web admin interface, create a network share named "Runs." I then added the IP of the RHEL server to the permissions list:
On the RHEL server, I then added the following line to /etc/fstab:
[IP of NAS]:/Runs /mnt/gsrnas3 nfs defaults 0 0
Aside from the IP and the specific mount directory name, this is how I mounted the other two NAS devices.
I then created the gsrnas3 directory under /mnt/, and then ran `mount /mnt/gsrnas3'
I got the following error:
mount.nfs: Connection timed out
My first thought is that it's a ports issue, but I don't have enough specific experience with this issue to know for sure. I have two other NAS devices by the same manufacturer already mounted to this RHEL server, so that leads me to believe the configuration issue is on the NAS side of things. I can ping the NAS device successfully from the RHEL server. Not being able to SSH into said NAS is a huge hassle, though. Any ideas?
