From time to time, I am getting, "cannot receive new filesystem stream: destination has snapshots" error with pve-zsync task. To fix it, I have to delete all snapshots. What could cause this?

I was able to create two task so : root@backup:~# /usr/sbin/pve-zsync sync --source 1.2.3.4:101 --dest D3 --name 101DAILY --maxsnap 10 --method ssh root@backup:~# /usr/sbin/pve-zsync sync --source 1.2.3.4:101 --dest D4 --name 101WEEKLY --maxsnap 10 --method ssh Then I was able to see...

As far as source will be same, do not I have any option for multiple task for different time internal like weekly and daily sync jobs ?

I think it is not with crons because one job which is daily will eares weekly one. So I meant to create two seperate sync jobs. But this time I will also (I think) need to create two dataset for each jobs.?

I want to take snapshos of zfs weekly and daily. So can I create two cron task like: /usr/sbin/pve-zsync sync --source 1.2.3.4:100 --dest D3 --name 101DAILY --maxsnap 10 --method ssh and /usr/sbin/pve-zsync sync --source 1.2.3.4:100 --dest D3 --name 101WEEK --maxsnap 10 --method ssh

Sometimes, I see high disk io in GUI. How can I see what really causing it in ssh ?

Can I now install it nvme disk ? Has someone tried? Is this fix for https://forum.proxmox.com/threads/nvme-zfs-problem.30727/

How do I mark as Solved ?

not yet as I need to wait for couple of days. But so far so good..

Ok I think I found the reason. It seems to be bug with OS. See: https://wiki.hetzner.de/index.php/Low_performance_with_Intel_i218/i219_NIC/en

Server is located at hetzner and they say it will take around 14 hours to check hardware which is too long for me. I loose all connection to server ssh, ping etc. and I send a hardware reset from panel and it becomes online again. Only things I found in logs are; but in two months, this...

But anything I would see via kvm, must be also in log files? I am thinking of moving to a new server.

My proxmox lately hangs or loose connections and I have to reset node to become online. But I can not see any failure in logs. Actually not sure which log to look at. Can you please guide ? I look at all logs files but can not see anything.

Sorry I did not mention that; after I tried zerofilling this vm, I see its size 250GB but other wms are not same, For example vm 113 has 50 GB limit and I can see the real usage in listing (20GB), NAME USED AVAIL REFER MOUNTPOINT P2/vm-113-disk-1 20.8G 1.07T...

Thank you. I read many articles but confiused. I enabled thin-provisioned on storage AFTER wm is created and used for some time. But it did not change anything. What must I check? Do I need to zerofill disk inside vm?

I am using zvol. Windows kvm has 250 GB disk and only 150 GB is in use. But zfs list show as: NAME USED AVAIL REFER MOUNTPOINT P2/vm-124-disk-1 250G 1.07T 250G - Is this normal?
