Is it safety to use cv4pve-autosnap in conjunction with Storage Replication (pvecm)?

[GusevVictor]

Hi all! I'm very like to use cv4pve-autosnap for years. In all time when I use it, I have a question about safety use it with Storage Replication (pvecm).

For example:

1. case when cv4pve-autosnap runs for create a new snap and del some old snap while pvecm (send diff/full snapshot)
2. case when pvecm runs for create a new or del old diff snap while cv4pve-autosnap want to runs too.

There is vm lock, but I have doubt about that will be work good.

It there any dangerous when use both tools?

what command do you use with pvecm?

First of all: Thank a lot for your answer.

I use gui of proxmox replication. I mean this one:

Hi, this is replication vm. cv4pve-autosnap uses the API and there is no problem

Best regards

Thank you so much. Yes, I understand about API. Below of the API resides zfs layer and I don't know what about when zfs send snapshot and during this cv4pve-autosnap send by API - "HEY! We need delete this snap." - Is there possible to destroy of zfs tank at all? :)

Will be glad for any update :)

Don't worry, it will be safe. The PVE API serializes all commands and organizes them to avoid conflicts (snapshoting while replicating is an example). I've been using autosnap for months on 8 nodes, replicating vms between them.

Thank a lot. I have some error messages like this one: command 'zfs snapshot tank/vm-113-disk-1@__replicate_113-0_1675396830__' failed: got timeout

Think this is no so dangerous.
