Remote Mount plugin OK but no Share Folder ?

Hi

On Linux 4.17.0-0.bpo.1-amd64 / OMV 4.1.9 (Arrakis) :
I mount well remote NFS devices with Remote Mount Plugin / NFS , but they are invisible in Access Rights Management/Shared Folders ?? Why ?
(I want that to do Rsnapshot jobs)

Thanks in advance for any help..

Hi ryecoaaron and thanks to take time to help me (us)

1/- I can create (or I don't see if it must be created automaticly after remote mount connected) a share folder based on remot mount device
2/- nfs shares are in not nfsv4 (not checked in my remote mount config)
3/- after remote mount added, I can see them in File Systems i see their size used, available stauts = online, mouted = yes, ...

root@SRVBKUP02:~# grep nfs /proc/mounts
192.168.1.31:/Data2 /srv/27a65d48-66bf-4967-bcf0-b66e227286cb nfs4 rw,relatime,vers=4.2,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=14,retrans=2,sec=sys,clientaddr=192.168.1.26,local_lock=none,addr=192.168.1.31 0 0

I use the same cibles on another srvbkup01 (omv 2.2.14) but with Remote Shares plugin... NFS conflicts beetween two server who want to mount the same cibles ???

Hello Ryecoaaron

"nfsvers=3" refused in option box, does some thing wrong in my config ? (this remotemount is in older version of omv and linux ...)

same issue from srvbkup02 side in edit mount

Hello ryecoaaron

Yes i'm considering the upgrade gradually, but before i'm testing omv4

Sorry, i'm not sure to understand well "I updated the plugin to support nfs v4."
- wich one ? remote mount ?
- how to update it ? do I have to load an upgrade ? which one ? I did not seen any thing about remote mount in omv update manager

Yes in Update Management I clicked Check
- first item of the list "intel-microcode 3.2018..."
- last one "Winbind 2:4.5.12+dfsg..."

Plugin : omv 4.1.10 installed

In OMV Extras I did an click on Update

I reboot the system

-> no change

PS : I remote mount on my OMV4 a volume from an OMV3, with or without the option versNFS=3 (or2) same issue as discribed in my first post (i see it in file system but not in Shared Folders)

Yes !

It works with remote OMV3...let's see OMV 2 and 1 ...

Thanks a lot ryecoaaron, I can progress to my OMV4 upgrade way ...

with remote server on OMV3 : yes "grep nfs /proc/mounts" give the same "nfs4" but the share works (with or without "nfsvers=3" option)

root@SRVBKUP02:~# grep nfs /proc/mounts
192.168.1.31:/Data2 /srv/7f0757af-0b3e-4a45-8109-8af7cfacfc0e nfs4 rw,relatime,vers=4.2,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=14,retrans=2,sec=sys,clientaddr=192.168.1.26,local_lock=none,addr=192.168.1.31 0 0
192.168.1.31:/Data2 /sharedfolders/RM_im_SRVDATA2 nfs4 rw,relatime,vers=4.2,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,timeo=14,retrans=2,sec=sys,clientaddr=192.168.1.26,local_lock=none,addr=192.168.1.31 0 0

i can't reproduce this success with remote server on OMV1 and 2 :
Error #0:OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C; mount '/srv/7ac743fe-2a09-4e73-824d-c9917a44e13c' 2>&1' with exit code '32': mount.nfs: requested NFS version or transport protocol is not supported in /usr/share/php/openmediavault/system/process.inc:175

yes, i tried with nfs4 option, nfsvers=3 option and nfsvers=2 option
