MeshCentral fresh Install: WARNUNG: Unable to find mongodump, MongoDB database auto-backup will not be performed

NethServer Version: 7.9.2009
Module: MeshCentral

Hi Markus

On a freshly installed NethServer as VM on Proxmox inside a Hetzner Cloud, I’m getting the following error on first log-in on MeshCentral. The server is completly up-to date as from NOW !

MeshCentral is installed as virtualhost with working LE SSL certs. NethServer has only one NIC, Internet / Firewalling is done with an OPNsense. LE is done by NethServer.

During the install of MeshCentral (done with SSH from remote) no issues were reported…

The Problem?

WARNUNG: Unable to find mongodump, MongoDB database auto-backup will not be performed.

How can this be fixed? (I suppose installing mongodump, but which version and how?).
I didn’t get this error the last time I installed MeshCentral (a few months ago).

Thanks iA!

I need to check, maybe something changed in newer versions of meshcentral…

bug

I'm running MeshCentral v0.7.47 with NodeJS v12.20.1 on Debian 10 and I'm using …MongoDB v4.4.3 as the database backend. I've verified that the package `mongodb-org-tools` is installed and that the `mongodump` binary exists on my system. ``` whalehub@pdh:~# sudo apt list --installed | grep mongodb-org-tools mongodb-org-tools/buster,now 4.4.3 amd64 [installed,automatic] ``` ``` whalehub@pdh:~# mongodump --version mongodump version: 100.2.1 git version: 0cb6f592fcb425ee5b3d5540341de75531d28dac Go version: go1.12.17 os: linux arch: amd64 compiler: gc ``` The appearance of this warning appears to be a purely visual bug in my case since I can see that MeshCentral has been creating its daily database backups in the `meshcentral-backup` folder just fine.

@pike

I installed last night, I still don’t see any Backup (yet).
It could be OK, but I’ll have to wait until tomorroy to verify…

At the moment, /var/lib/nethserver/meshcentral/backup is still empty…

You may create a symlink in /usr/bin to /opt/rh/rh-mongodb36/root/usr/bin/mongodump, this way mongodump is found by meshcentral and the message should disappear.
I’m going to add the symlink in the next update.

@mrmarkuz

Hi

Might be a bit difficult:

seems a “rh” is missing in /opt/rh/rh-mongodb36/root/usr/bin/mongodump…

But if the path is corrected, your solution works!
Sorry, was a bit to early. the error still remains.

Thanks!

Nethserver-meshcentral depends on rh-mongodb36, so it should be installed…

[root@testserver2 ~]# yum deplist nethserver-meshcentral
...
  dependency: rh-mongodb36
   provider: rh-mongodb36.x86_64 3.0-18.el7.sc1

EDIT:

Yes, you are right, I’ll correct my post…

Andy_Wismer · October 24, 2021, 8:38pm

Seems to be all there…

A reboot was needed - i suspected as much…

You know the old german saying:

“Reboot tut immer gut”…

freely translated into english:
“A reboot always does a lot of good”…

The error message is now gone.
Maybe a restart of the services would have been enough…

like this

more precisely:

ln -s /opt/rh/rh-mongodb36/root/usr/bin/mongodump /usr/bin/mongodump
