 |
|
Hi,
I have a problem with my NFS on this computer. Yesterday, it was working like a charm but now I had to restart the server for a RAID expand and it's not working anymore:
On the client:
| Quote: | /etc/fstab
# NFS
192.168.20.101:/movies /mnt/movies nfs rw,_netdev,auto 0 0
192.168.20.101:/music /mnt/music nfs rw,_netdev,auto 0 0
192.168.20.101:/documents /mnt/documents nfs rw,_netdev,auto 0 0
192.168.20.101:/series /mnt/series nfs rw,_netdev,auto 0 0
192.168.20.101:/multimedia /mnt/multimedia nfs rw,_netdev,auto 0 0
192.168.20.101:/backups /mnt/backups nfs rw,_netdev,auto 0 0 |

I've tested from two different clients, I have the same errors. Something must have changed on the server, but I didn't find any packages related to NFS in the Gentoo logs. I didn't update the kernel on the server. After it didn't work, I did try to reboot both the servers and the client, to no avail.
On the server:

What could have caused this ?
I'll gladly provide more information, but I don't know twhat information to give, just tell me what you need, and I'll send the information.
Thanks
Baptiste

wichtounet,
Try mounting with nfsvers=3 unless you are sure that version 4 is off on the nfs fileserver.

I just tried and it gives the exact same error.
Weirdly, if I force to nfs v4, I have a timeout. |

I found the issue...
For some reason, the nfs-server systemd service was not started anymore... Something must have changed in the systemd service files or dependencies and the server was not automatically started.
I should have checked before...
Thanks guys
