[SOLVED] [pve-zsync] error on local sync

[DzAirmaX]

Hi,

I think I found a possible bug in pve-zsync. The schema is simple:

• I want to create a snapshot of a pool to a dataset on another pool
• This is a local snapshot, no ssh
• Both of the pool / dataset exist
  • source: rpool
  • dest: test/weekly

Here is the full error msg:

pve-zsync sync --source rpool --dest test/weekly --name test1 --maxsnap 4 --method local
Use of uninitialized value in concatenation (.) or string at /usr/sbin/pve-zsync line 898.
COMMAND:
        zfs send -- rpool@rep_test1_2016-09-08_00:20:23 | zfs recv -F -- test/weekly/
GET ERROR:
        cannot receive: invalid name

The problem is that the snapshot is not created on rpool, so it cannot be sent.

I thought first it was a zfs restriction. But "zfs snapshot rpool@test1" does create a snapshot of the pool.

zfs list -t snapshot
NAME  USED  AVAIL  REFER  MOUNTPOINT
rpool@test1  0  -  96K  -

I think pve-zsync is struggling with creating snapshot at the "root" level of a pool...
What is your thinking? Is a fix possible?

Hi,

this is not a bug.
What you try to do is a recursive send/receive and this is not implemented.

Thanks for your quick answer.

Is that something you will implement in a near future?

There are no plans for this, but you can make a feature request on bugzilla.
