Remote Mount & Rsnapshot

Hello

i tried to remove the mount on the remote mount tab and get the same error again:

Failed to get the filesystem implementation for 'f3cb2b35-616d-4cd0-a004-49b05bb427b4' or the filesystem does not exist.

Fehler #0:exception 'OMV\Exception' with message 'Failed to get the filesystem implementation for 'f3cb2b35-616d-4cd0-a004-49b05bb427b4' or the filesystem does not exist.' in /usr/share/php/openmediavault/system/filesystem/filesystem.inc:855Stack trace:#0 /usr/share/openmediavault/engined/module/fstab.inc(84): OMV\System\Filesystem\Filesystem::assertGetImpl('f3cb2b35-616d-4...')#1 [internal function]: OMVModuleFsTab->deleteEntry(Array)#2 /usr/share/php/openmediavault/engine/module/moduleabstract.inc(145): call_user_func_array(Array, Array)#3 /usr/share/openmediavault/engined/module/fstab.inc(44): OMV\Engine\Module\ModuleAbstract->execTasks('delete')#4 /usr/share/openmediavault/engined/rpc/config.inc(147): OMVModuleFsTab->stopService()#5 [internal function]: OMVRpcServiceConfig->applyChanges(Array, Array)#6 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#7 /usr/share/php/openmediavault/rpc/serviceabstract.inc(150): OMV\Rpc\ServiceAbstract->callMethod('applyChanges', Array, Array)#8 /usr/share/php/openmediavault/rpc/serviceabstract.inc(528): OMV\Rpc\ServiceAbstract->OMV\Rpc\{closure}('/tmp/bgstatus0m...', '/tmp/bgoutput0i...')#9 /usr/share/php/openmediavault/rpc/serviceabstract.inc(151): OMV\Rpc\ServiceAbstract->execBgProc(Object(Closure))#10 /usr/share/openmediavault/engined/rpc/config.inc(208): OMV\Rpc\ServiceAbstract->callMethodBg('applyChanges', Array, Array)#11 [internal function]: OMVRpcServiceConfig->applyChangesBg(Array, Array)#12 /usr/share/php/openmediavault/rpc/serviceabstract.inc(124): call_user_func_array(Array, Array)#13 /usr/share/php/openmediavault/rpc/rpc.inc(84): OMV\Rpc\ServiceAbstract->callMethod('applyChangesBg', Array, Array)#14 /usr/sbin/omv-engined(516): OMV\Rpc\Rpc::call('Config', 'applyChangesBg', Array, Array, 1)#15 {main}

After that i check the /var/lib/openmediavault/fstab_tasks.json. There is a entry, which i clear: echo "[]" > /var/lib/openmediavault/fstab_tasks.json and after omv-mkconf fstab.

I deinstall the plugin (purge), clear the fstab_tasks.json, restart the system, check the fstab_tasks.json, install the plugin and retry it (create mount, delete mount) ... get the same error.

I create a fresh installation of OMV3 in a virtual machine. After installing the omv-extras and remote mount, i create a new nfs mount on the remote mount tab.

And .... the same error: the mount isn't displayed on the shared folder wizard and i get the following error on apply delete:

Failed to get the filesystem implementation for 'fb8932a2-aa45-4399-b4cc-6ea1bf0e9358' or the filesystem does not exist.

Can you please send the output of /proc/mounts on your testsystem, where nfs is working ?

SMB is working. Is there maybe a problem with my /etc/exports ?

/export/brocken 192.168.1.202(rw,all_squash,no_subtree_check,anonuid=0,anongid=0)

Have you an idea, why i´m getting the exception on delete ?

I have debug your plugin and find the reason.

I create my mounts on the remote mount tab without NFS4. But the system create a nfs4 mount (cat /proc/mounts).

The problem is the function getImplByMountPoint. There are no backends for nfs4 - only for nfs (/usr/share/php/openmediavault/system/filesystem/backend/nfs.inc).

Workaround:
I add "nfsvers=3" on fstab (later on the plugintab) and remount my nfs-share. Now its called nfs on /proc/mounts.

nfsvers=3 vers=3 "The NFS protocol version number used to contact the server's NFS service. If the server does not support the requested version, the mount request fails. If this option is not specified, the client negotiates a suitable version with the server, trying version 4 first, version 3 second, and version 2 last."

Maybe nfs4 is on your remote server disabled?

I don`t use nfs much, too. Only for rsnapshot :P.

"nfsvers=3" in options on the plugintab works for me

Today there was a update for openmediavault: Fix bug when a non-existent file system will be removed.
