But it does nothing. there are still plenty of chunks in /mnt/datastore/XXX/.chunks/ I don't know what to do to get back an empty datastore before the tonight backup.

I'm in a situation I don't understand and I don't know what to do. To prevent it happen again, I deleted little by little all content from my Datastore. Deleting one didn't do anything, neither the second and so on... And now I have deleted all, the storage remain full. I can't even do zfs...

Thank you so much for these information. I'll keep them very preciously.

I'm facing this issue and I'm struggling to solve it. I can't even make Garbage collect as I gives me the same issue too. I'll try moving some chunk files in order to be able to make a Garbage collect but it isn't a pleasant task and it is very stressfull. I wish there would be an option to...

Solved : /usr/share/proxmox-acme/lebureaunsupdate.key should content something like : ``` key "lebureau_coop_mydomain_com" { algorithm hmac-sha512; secret "KEY_VALUE"; }; ```

Hello, I created a file /usr/share/proxmox-acme/lebureaunsupdate.key with the content : ``` key "update" { algorithm hmac-sha512; secret "AAA/MY/SECRET/AAA=="; }; ``` and I filed the acme plugin like that but when I try to order a certificate, I get the following error : ```...

Sorry, I meant Proxmox Backup Server. Thank you for your answer. I don't understand what you meant by pve and the VM are indeed running on a 1TB SSD. The VM has a 900GB disk on the ZFS pool. Do you mean that with such conf, an ARC Max size set to 2GB would be enough and I can keep the VM to...

Thank you. What would you recommend instead of ZFS to be able to benefit from snapshot and proxmox backup?

Hello, I have a pve running on a 8 GB RAM computer with ARC Max size set to 3 GB and a VM set to 5 Gb (4GB min and ballooning enabled) but I got an oom-kill last night (so the backup failed and the VM remain down till I check) and I wonder how can I avoid it to happen again. Here are systemctl...

I don't know, I read it's stop mode is providing the highest consistency of the backup. I didn't get what you recommend. You seem to say that having guest-agent enabled, I should choose an other mode but I didn't get which one and why guest-agent change something about the choice. Would you mind...

I'm trying to backup manually. Shutdown took about 1 min and the backup is now running (around 3%). It has already pass where it was failing previous nights. [edit] : manual backup shutting down the VM did work!

Hello, I set up a backup of a VM with stop mode. It used to work nicely before the day before yesterday. Now, I get the following error : INFO: starting new backup job: vzdump 100 --notes-template '{{guestname}}' --mailnotification failure --quiet 1 --mode stop --prune-backups...

I tried to look for it in PBS GUI and could not find how to create a "dataset". Could you give me some detail how to do so? And @Neobin what do you think of leesteken solution?

I'd say that the main usage is PBS and PVE is secondary. I think pbs will be use mostly during night so I was wondering who I can use this computer during the day and that's how I got the idea to use it for test and preprod VM.

No, it's not for windows. Again, PVE would be used only for testing and pre prod VM so I won't backup them and PBS will get backup from other PVE from other remote computers.

One last wonder that might solve everything. Is it possible to use PVE's 16TB ZFS RAID 10 rpool as a datastore in PBS? Like that I have only one ZFS zpool of 16 TB on which I install PVE and PBS, somme testing VM and the datastore too.

Hello, I have a computer which have currently 4 HDD of 8TB each but I may be able to add one SSD to it. I want to install a PVE for pre-production that I would use during the day and a PBS that would receive backup from prod computer at night. I wonder if I should either : - install PVE and...
