Good day! I have some massive I/O full stall with a software Bitcoind. Let me explain the issue.

I have a p330 running on Raid 1 ZFS proxmox. I have a SSD 2.5 enterprise SDA P883 Samsung.

I have Zfs the SDA Samsung P883 and I have a production node on it which mean I run Bitcoind and LND. Separated of the Raid 1 proxmox install.
I wanted to monitor my system so I installed as well Grafana and I realize that Bitcoind full sync fully operational was writing about 10 gb of data each hour create A MASSIVE FULL STALL I/0 about 20% each hours...

This is not normal at all Bitcoind should only write read few mb 4 mb by block really...
I do not know much about proxmox but would this be an issue related to proxmox? Few of my friend that run node does not have issues with ZFS so I doubt it could be... The vm run ubuntu Ext4 format...

Would anyone see massive spike I/O running bitcoind each hours?

I put a screenshot to explain it better but 10gb of writing instead of few mb that my friends got seems to be excessive!

Thank you
