PBS: error fetching datastores - 401 Unauthorized (500)

[adminkc]

Hi all,

if I try to connect the PBS to my nodes I get the following error: PBS: error fetching datastores - 401 Unauthorized (500)
Is this error known?

Best,
KC IT-Team

do you use the correct user with the correct permissions? any logs on pbs side (syslog/journal)?

 

[adminkc]

Okee the one error is now ok.

I get a new error kcs-pbs: Cannot find datastore '/mnt/datastore/rpool', check permissions and existance! (500)

I try everthing and nothing work?

Best

 

[dcsapak]

you have to put your datastore name in, not the path

 

[adminkc]

the same error if i put only the datastore name: kcs-pbs: Cannot find datastore '/rpool', check permissions and existance! (500)

 

[dcsapak]

you have to put the name of the datastore (as defined in pbs) in the field 'datastore' (you have /rpool there now)

 

[adminkc]

The name of datastore is rpool.

 

[dcsapak]

yes but without the slash '/rpool' vs 'rpool'

Datastore --> Permissions --> add

add you need user

like down image

The fix is to create an admin user shown in this video.

You will then have no connection errors between the VE and PBS servers

I had the same problem with me, it was because I had set up 2-factor authentication with the PBS. After I removed them, everything was integrated correctly again

same here, after removing 2.factor everything is ok again

Same here, but I would like to use 2FA auth. How can VE backup to PBS with activated 2FA? Same happens on sync from PBS <-> PBS

hi, you have to use a token instead of the actual user. 2fa does not make sense really for automated stuff (like the pve -> pbs backup)

The solution is : Choose Linux When you Downloading Backup Server Proxmox and setting , not Windows

Creating the user from the video, and using the <user>@pbs worked.
I tried to use my hostname so it was <user>@pbs01. That does NOT work.

Thank you for this thread.

In case someone is running into this issue, also do check what the users authentication method is. If the user is available locally, use pam, instead use PBS.

So, local account (i.e. root):
Username: root@pam

PBS acount:
Username: user@pbs
