tklbam-backup sts agent error after

David McNeill's picture

tklbam-backup is giving sts-agent error after running for a couple of hours...

It's got through 571 volumes of 25Mb, so configuration is obviously ok.

Then it gives sts agent error, which is something to do with auth token handling.

Does the generated token for s3:// have a limited life span?  Anyone know how long that is?

What happens if a backup can't complete in that time?

Is there any way to get more detail on that the issue is?

Kicked it off again, and it got as far as volume 1404 a couple of hours later.

Site is on 100Mbit fibre, so a good connection, and transit is from Auckland -> Sydney.

Sort of implies tklbam is good for about 20 to 25Gb compressed backups in it's current state.

This does seem to be a change, as larger backups of 6,000 volumes were working last year.

Up to 2141 volumes, next morning, then same sts agent error.

AFAIK the tockens expire after one hour, but TKLBAM should request new tokens as it needs them.

Is this a v14.x server? If so, we have relatively recently released an updated TKLBAM build to make it more robust. Perhaps that will resolve your issue? (Or perhaps it's the cause of your issue?).

So please get the current TKLBAM version like this:

apt-cache policy tklbam

Assuming that you are running at v14.x server and haven't updated to the latest version, it should look something like this:

tklbam:
  Installed: 1.4.1+12+gd34d79b
  Candidate: 1.4.1+17+g71478bd
  Version table:
 *** 1.4.1+17+g71478bd 0
        999 http://archive.turnkeylinux.org/debian/ jessie/main amd64 Packages
        100 /var/lib/dpkg/status

If the 'Installed:' version is NOT '1.4.1+17+g71478bd' then please run "apt-get update && apt-get install tklbam" and retry.

If you continue to have these issues after updating to the latest TKLBAM (or you were already using it) then please let me know ASAP and I'll get Liraz to look into it.

Still on wheezy with Univention Memberserver 4.0-3.  Will have to upgrade that circus first.

apt-cache policy tklbam
tklbam:
 Installed: 1.4.1+3+g8005390
 Candidate: 1.4.1+3+g8005390

Jeremy Davis's picture

I'll update Liraz with that info.

Perhaps we should look at backporting the latest version of TKLBAM to v13.x too?
