I have a server setup (2.6.10 vanilla kernel, nfsroot with local hard disks
that are exported). Recently the motherboard died and had to be replaced.
No configuration changes were performed to the system otherwise. Now I see
Permission Denied errors when attempting to mount any of the exported
directories. Server is called "nail" with IP of 192.168.2.15 (x86)
kmountd nfs-utils 1.0.6
exports:
/backup 192.168.0.0/255.255.0.0(rw,async,wdelay,no_root_squash)
/160g 192.168.0.0/255.255.0.0(rw,async,wdelay,no_root_squash)
/80g 192.168.0.0/255.255.0.0(rw,async,wdelay,no_root_squash)
Those are hdc sda and hda respectively
The clients are "vegeta" 192.168.2.7 2.6.12 (x86) and "kakarot" 192.168.2.6
2.4.20 (alpha)
The only workaround I found is to use exportfs -f and everything works fine.
I can't understand why this is now giving me problems.
I set nfsd_debug to 65535 and I see this:
Oct 28 21:14:27 nail kernel: nfsd: exp_rootfh(/backup [ef3c15a4]
192.168.0.0/255.255.0.0:hdc/2)
Oct 28 21:14:27 nail kernel: nfsd: exp_rootfh export not found.
However, running exportfs shows:
/backup 192.168.0.0/255.255.0.0
/160g 192.168.0.0/255.255.0.0
/80g 192.168.0.0/255.255.0.0
After exportfs -f:
Oct 28 21:15:07 nail kernel: nfsd: exp_rootfh(/backup [ef3c15a4]
192.168.0.0/255.255.0.0:hdc/2)

At this point I have no idea what's going on.
