Hi
We have strange problem with Proxmox VE 5.3.8 + Dell SCv2020 over FC.
HDDs in storage have 512n sector size but fdisk reports physical sector size 4096 and also I/O size is very high.
On top of that we use multipathd.
After i create VM on this volume and install OS i get this error:
VM works but there no problem like this Dell Eqallogic over iSCSI.
Thanks for advice
