@Sergei_Genchev Welcome to the Rockstor community.

This is due to the minimum system requirements for Rockstor not having been met by VMware by default.

Please see our Quick start doc section specifically the Minimum system requirements:

  • All drives must have unique serial numbers (real drives do); not all VM [*] systems default to this

where the [*] references the following inline note:

[*] For VMware ensure you have disk.EnableUUID=“true” in your .vmx file

Hope that helps.
