"Target exists but has no matching snapshots!" Incremental sync not working about sanoid HOT 7 CLOSED

Very strange. Can you give me info on distro and version (ie Ubuntu 14.04
or whatever) on both sides please?

(Sent from my tablet - please blame any weird errors on autocorrect)

Hi there,

first of all thanks for your effort. So far i really like Sanoid :)

But unfortunately syncoid doesn't work for me.

I try to pull my VM dataset from my server (n1) to my secondary server.
The first sync with syncoid seems successfull, but incremental syncing
doesn't seem to work.

I tried this now several times. Removed all snapshots and made new ones
with sanoid.
It's always the same.
The first sync works, succeeding ones stop with:

CRITICAL ERROR: Target exists but has no matching snapshots!

Maybe i'm making some errors, but i don't know what I'm doing wrong...

Could you have a look at this?

Thanks in advance!

Here are some infos:

Both nodes run Proxmox VE.
n1 has VMs running.
n2 was fully reinstalled yesterday.

Both have the latest sanoid files (yesterday downloaded) in /usr/local/bin/sanoid/

from sanoid.

Just a quick follow-up:
I updated n1 to the latest kernel and debian version 8.5 and rebooted.
Then i destroyed again the dataset on n2, removed the syncoid snaps on n1 and started all over with a completly new sync.
The first syncoid run succeeded, the following sync failed again.

Error message was the same as before.

from sanoid.

Finally i resolved the problem.

sudo was missing on my target machine n2.

Maybe you could add some package requirements to the readme.
For debian i also had to install some perl dependencies.

These are the dependencies i needed on debian jessie 8.5:

perl -MCPAN -e 'install Perl::OSType'
perl -MCPAN -e 'install Module::Build';
cpan install Config::IniFiles
apt install mbuffer lzop pv sudo

from sanoid.

You shouldn't need mcpan - I believe debian has libconfig-inifiles-perl in
repos, just like Ubuntu does.

apt install libconfig-inifiles-perl

(Sent from my tablet - please blame any weird errors on autocorrect)

Well, maybe i should have checked that first :)

Anyway thanks. On my next install i will try that.

So far sanoid and syncoid chug along happily now.
Keep up your good work :)

from sanoid.

It definitely does. I run it on Proxmox (Debian).
