@bvitnik Not really, what is elusive here is if we can reduce the auto scan frequency and why is set by default to frequent but that to cause the increase of logs is the auto scan is quite clear from MajorP93 test.. The auto scan log shows a lot of lines for each disks and when you have like 400 - 500 disks and you scan them every 30 seconds you definitely have a lot of logs. I think the log partition is quite small to be honest but the logs is also very chatty.

Create an appliance with all those VMs and configure the order and delay inside it.

@manilx there is some cheap NETGATE appliances (Netgate 1100 or 2100) to put your PFSense+ out of virtual infrastructure. this is the way.

@pilow : thanks for let me know your experience. I was afraid someone would say that. Unfortunately for us going out of XOSTOR is not so simple because we really need VM mobility to allow for host maintenance which otherwise we would not be able to perform and budgeting for a redundant external storage is not an option either. The annoying thing is that before start this journey with Vates we did engage with them and made them aware of our environment ( it is a migration from vmware) and no one has ever mention that could have been a problem to store so many VMs into xostor so I am really hope that support can shed some light and provide some fix to the situation. Overall is not a bad experience but waiting for 3 / 4 minutes for a VM to start when you are in hurry is not really great.
