@siringo said in Windows Servers Archived onto Linux, suggestions/help pls:
Just installed Proxmox on a Dell T620 with 4 x 600GB physical disks.
Proxmox tells me this:
When I installed I didn't install any RAID option, I just chose the default.
I know this is elementary for you linux guys, but is that telling me that it has used 3 of the disks to create a volume of size 557.87GB?
If not and it's only using 1 physical disk, how can I add more disks for Proxmox to use?
Thanks for any help.
You must be looking at LVM under Disks because that’s normal. Take a look at LVM-Thin under Disks.

Default is to assume that you are using hardware RAID, that's by far the standard in the SMB and micro-computer industries. No one is going to do software RAID as a default as there's almost never a case where people want that - to the point where VMware has no accommodation for software RAID and Hyper-V has no production ready software RAID options. So while ProxMox has solid enterprise grade software RAID, the ecosystem that they are used in will rarely want to use it, it's nearly a foregone conclusion in the micro-server space that hardware RAID will always be used (because of VMware, Hyper-V, and Windows needing it.)

LVs are logical volumes. This isn't a Linux thing, this is the same on every OS including Windows. LVs are what we've used since the late 1990s instead of partitions. They are a more powerful mechanism with abstraction and no direct tie to the hardware.
Windows confusingly uses LVs but doesn't label them that, instead they call them "dynamic disks". But LV is the generic term that applies in all cases.
So your PVE system is saying that on the physical partition /dev/sda3 you have a logical volume manager (e.g. using dynamic disks) and it is split into three volumes. The total size of the physical device is 557GB and all of it has been used by the volume manager at this point. That's all it is saying.

The way you WANT to do it is to put them into RAID. Do you not have hardware RAID? If not, that's fine. Just think of it as "doing something complex enough that VMware and Hyper-V don't really accommodate it, technically Hyper-V does, just not in a way you should trust yet and has a train wreck of a track record.)
But, in general, RAID isn't another thing you'd want to be learning here. Treat it like VMware or Hyper-V and stick to hardware RAID that takes care of all of this for you.

Thanks for the info Scott, I appreciate it.
It's the next day now, what I was wondering yesterday was had Proxmox created a RAID set out of the 4 disks in the server? The confusion came about as what Proxmox seemed to be telling me yesterday was it had used 3 disks, which to me looked like a RAID set with the capacity of a single physical disk.So I was wondering if it had created a mirror with a hot spare???
If it hasn't done that, then I'd like to add the extra disks for Proxmox to use so I can learn about Proxmox as I play, this is just a lab server.
This is what is shown under LVM-Thin

That looks like a single drive to me. Can't be sure without seeing the outputs from
zpool status -l -
@siringo During the installation setup you do have an option to use raid by using ZFS but it’s not selected by default. I’ve never used it because I’m using hardware raid.

Yep I can remember looking at that option when installing, but it came up with a message along the lines of "that option is not supported etc" so I just went with the default.

The defaults we're very likely no raid at all and to use a single disk.

No zpools by default.

No zpools by default.
That would confirm it for sure!

Thanks for the help everyone, just become very busy.
I get this:
What does that tell us?

That you went with the default setting, so are only using a single drive.

Oh, great. Thanks travisdh1, we got there in the end. Now I know I can add the extra disks.
