Hello, I stumbled upon this bug after migrating two uncritical VMs and after setting up new ones with Ubuntu 20.04. The host system for the VMs is running esxi 6.7.
After searching for the error I found one interesting forum post [1], wich solves the problem with options on the hosts system (VMware ESX). After setting the option "disk.EnableUUID" to "true" mutipathd is not reporting any "failed to get ... uuid". But not everyone has access to the host system. Also the solution in Comment 17 [2] solves the problem. One VM uses raw disks and there the error doesn't occur. Also the vendor and product of raw disks differs from the default vmdk in a data store. Some interesting finds: "multipath -v3 -ll": Using a default vmdk: sda: fail to get serial Using a default vmdk with disk.EnableUUID enabled: sda: serial = 6000c29adee74d1efcd3057f58416b7e Using a raw disk: sda: serial = 021845000405 Hope that can help. If you need more infos, let me know.
