zarkoff Posted March 29 Share Posted March 29 (edited) Hello, I have NFS shares since a while and it has always worked until now. Today I've installed 6.12.9 version and since, I can't mount NFS shares anymore (same for SMB). I can detect and find the shares I want to add but impossible to mount them anymore. I've the following message : Device 'xxxxxxxxxxxx' failed to mount. Check the syslog for details. and I don't know what or where to check. Do you know what can I try ? (share are on a Synology NAS, I used them for plex) Syslog says: (xxxxxxx = shares name) Mar 29 21:03:08 Lab unassigned.devices: Mounting Remote Share 'xxxxxxxxxxxxxxxxxx'... Mar 29 21:03:08 Lab unassigned.devices: Mount NFS command: /sbin/mount -t 'nfs' -o rw,soft,relatime,retrans=4,timeo=300 'xxxxxxxxxxxxxxxxxx' '/mnt/remotes/xxxxxxxxxxxxxxxxxx' Mar 29 21:03:08 Lab unassigned.devices: NFS mount failed: 'mount.nfs: Protocol not supported '. Mar 29 21:03:08 Lab unassigned.devices: Remote Share 'xxxxxxxxxxxxxxxxxx' failed to mount. NFS mount failed: 'mount.nfs: Protocol not supported... well does it mean I need to downgrade or something ?

DB_O Posted March 30 Share Posted March 30 same problem for me after Update to 6.12.9 My backup-share on a synology can't be mounted anymore Quote Link to comment
JorgeB Posted March 30 Share Posted March 30 IIRC NFSv2 is no longer supported, only v3 or v4, try to see which version the Synology is using. Quote Link to comment
zarkoff Posted March 31 Author Share Posted March 31 Hi Thank you for your answer. In Synonlogy (DSM), NFSv2, NFSv3 and NFSv4 are all activated... and I'm not an expert but what I understand is that the version is determined by the way it is mounted. On Synology - DSM (https://kb.synology.com/en-id/DSM/help/DSM/AdminCenter/file_winmacnfs_nfs?version=7)I read this: "When mounting, the parameter -o vers=2, -o vers=3 or -o vers=4 can be added to the mount command in order to specify which NFS version should be used." So is there a way to add this parameter when we try to mount ?? (a modification in Unassigned Devices plug-in for example ?) Quote Link to comment
JorgeB Posted March 31 Share Posted March 31 Suggest re-posting the issue in the UD plugin support thread. Quote Link to comment
Solution dlandon Posted March 31 Solution Share Posted March 31 When mounting NFS remote shares, UD uses a setting to request the server for the latest version of the protocol available. You can force UD to use NFSv4 settings when mounting NFS shares by setting the "NFS Version to use when Mounting Remote Shares:" to NFSv4. This disables the NFS request for version feature. There have been some changes in the latest Kernel in 6.12.9 that have probably caused this change in the way this works. Quote Link to comment
dlandon Posted March 31 Share Posted March 31 If that doesn't work, post back here. I have another suggestion. Quote Link to comment
DB_O Posted March 31 Share Posted March 31 set "NFS Version to use when Mounting Remote Shares:" to NFSv4 fixed the problem for me. My Synology Share is back Quote Link to comment
zarkoff Posted March 31 Author Share Posted March 31 (edited) Hello, I confirm it solves my problem too. Many thanks !! attached a screenshot for those who want to do the same change in 'Unassiged Devices' setting too : Edited March 31 by zarkoff Quote Link to comment
dlandon Posted March 31 Share Posted March 31 The real answer is to update UD. Then you won't have to change the UD setting. Quote Link to comment
zarkoff Posted March 31 Author Share Posted March 31 Ah ok, that's true that I did the change after the update of UD... so at the end I don't know what really solves (update or change in settings), so I suggest you do the both :-). Thank you. Quote Link to comment
dlandon Posted March 31 Share Posted March 31 Either one, but the "Auto" settng is best so UD will negotiate the server version. Quote Link to comment
zarkoff Posted March 31 Author Share Posted March 31 Ah Ok, so I'll change it back to 'Auto' Many thanks for your help. Quote Link to comment
