howdy. I'm using freenas on ssd disks & nfs share for proxmox vms disks.
have periodic snaphot task.
afaik, before creating new snapshot or after doing it, this task removing old snapshot that was made e.g. yesterday.
i've noticed that deleting old snapshot affects performance of vms that most sensitive for iops.
i having iowait on those vms.
i tried to change next sysctl values but it don't changed anything:
vfs.zfs.vdev.trim_max_active=32
vfs.zfs.vdev.max_active=64
how can i fix it?
thanks
