Re: NFS mounted but shows nothing even df -h has it

You made the point, thank you Maksim.

I checked /mnt/hdd and nothing there.

> # cat /etc/fstab
1593ab2ee369c420.b none swap sw
1593ab2ee369c420.a / ffs rw 1 1
1593ab2ee369c420.e /var ffs rw,nodev,nosuid 1 2
2b6c2b5b929f9a55.i /mnt/hdd ffs rw,noexec,nosuid,nodev 0 0

Disk: sd0 geometry: 121601/255/63 [1953525168 Sectors]

============
So /dev/sd0 is my NFS share hard disk, and when I tried to mount it manually:

> # doas mount /mnt/hdd
mount_ffs: 2b6c2b5b929f9a55.i on /mnt/hdd: Invalid argument

+++++++++++
The error message mentioned about "Invalid argument" of mount, anything wrong?

So the problem now is why can not mount the drive even it's detected?

Thank you,
