I/O wait everyday at 06:12

Hi,

I have a 7.2-5 host that every morning at 6:12 has a very high I/O wait. Is there something that PVE does at that precise hour? Like a a cron or something?

Thanks

fstrim -a -v may be started inside the VMs as a cron.daily job.

I don't have any job or cron in the CTs/VMs. I will try and update the cluster to 7.3. The disks are fine. The boot drive is a raid 1 of SSDs and there are 2 pools, 1 is ceph with nvme drives and the other one is a zfs mirror of NVMe SSDs.
