Ram used

[jaj1105]

Hello,

After installing proxmox ve 6.0-11 i used a lot of ram without any VM started.

Is it normal?

You have a screenshot in attachment.

I have a ZFS raid.

Best regards,

Joseph

Hi,

Is it normal?
I have a ZFS raid.

The ZFS ARC defaults to using half of the memory by default - note that some of it still can be reclaimed if there is need for memory in the system. But you can reduce it's default max-use-size, if you want: https://pve.proxmox.com/pve-docs/chapter-sysadmin.html#_limit_zfs_memory_usage

Thanks for your feedback, so I can leave at 50% and if my vm need more ram they will take in the ram used by ZFS ARC?
