@Bruce,
No you will not loose any data, as you can use second LVM as storage and first LVM for OS installation..

However, I wonder abouit having a second LVM? If so, and I have to reinstall the basic system, will I then lose the data in the second LVM?

I Currently have an Asius Maximus VI for my main workstation, but I make minimal use of the LVM for working data. Instead, I have 2 more 4 Tb. WD Red drives for the working data, and back up to 2 more NAS boxes from that, using a lot of Filezilla FTP, and a lot of filtering to get rid of garbage data arising out of characters that don’t suit my code page, 0 data files, etc.

I also use several docking stations (“Toasters”) and 2w mof Medicaonscs USB3 RAID boxes, each configured with 2 WD 4Tb. RED drives in firmware managed RAID0 volumes.

Some of those external drives, I hope to use with the server, as a way of reducing the processor burden on the main machine which arises from all the Filezilla filtering and sorting as it backs up file by file.

Drives used in the “Toasters” will be a way of having offline backups that are not powered until needed. Those drives can than be stored in metal toolboxes as a partial hedge against print through from the earth’s magnetic field.

but I really don’t like having to work in console mode. For SU, I think I have seen an RPM package that will allow the GUI to work as SU. That T.B.D. in forther experimenting.

@Almnssor,

@Rashid,
You’ve selected Federa 21 Server installation, which doesn’t provide any GUI mode, in order to have GUI on Fedora 21 Server, you need to install GNOME3 Desktop Environment using following command.

# yum groupinstall gnome
OR
# yum groupinstall "Fedora Workstation" --skip-broken
