Partitioning and Install on 3 NVMe disks

I can run some tests on it for that specific software. But my hardware is very inferior to yours.
As far as rendering time goes, if the rendering time is normally 1 second, then it may take twice as long.

That’s very kind of you, TY very much
my P15 is stock: i7-11850 8cores (16 virt), 24M cache; 128GB DDR4 (maxed to); Intel UHD IG + NVIDIA RTX A2000 12GB GDDR6 ; 802.11ax Wi-Fi 6, 2.5GbE;

@Vael_S

All depends what else you are doing on the machine and the quantity of resources that you have assigned to the renderer,

usually, when I’m on such work, I don’t do anything else, besides the occasional podcast or youtube.

@Vael_S

If it has it’s own dedicated resource pool that nothign else can touch or use, then that may also be advantageous for that, which is what I do.

I could indeed have the same core setups; as my day to day is mainly browsing (intensively, I currently have over 60 tabs on 3 browsers) and LibreOffice writing official doc, and a few spreadsheets

@Vael_S

I have set up VRAM assignment for the guests as well. So they have more VRAM available.
The default is set to 64MB for each guest by default, but the graphics intensive ones I do assign more RAM, generall up it to 128 or 256. Gaming I have at 2 GB (unless I use the passthru)

I haven’t seen DVMT in my bios, so I’ll probably be limited to the 12GB VRAM of the card itself

@Vael_S

And as I had stated, you can set it up to use Windows as a virtual system and appear as such when the USB isn’t in there. Meaning you would always be running under Qubes.

yes, and it is an interesting feature, which I will definitely try if/once I’m confident about removing native win10

@Vael_S

Only 2 GB. Then you would have to have the root file system on the 2TB then. But still, it’s only 24+ GB.

TY, good, so not 256GB for root, just 30-ish GB

@Vael_S

EXT2 is just EXT2, it is jsut EXT3/4 without the extra overhead. even disabling those features means that it still has to check those features if they are on or off when performing write operations. EXT2 doesn’t have that, so it saves time again.

Right.

• Performance : Ext4 is generally considered to be more performant than ext2, especially in terms of handling large files and directories. However, ext2 can be faster in certain scenarios where journaling overhead is a concern.
• File Size Limit : Ext4 has a much larger file size limit than ext2, with a maximum file size of 16TB compared to ext2’s 2TB limit.
• File System Size Limit : Ext4 also has a maximum file system size of 1 exabyte compared to ext2’s 32TB limit.
  => I think I’ll be ok with EXT2 indeed …
  What about ZFS ?

@Vael_S

Disabling the ports does not un-mirror the drives. It merely turns off the ports, so the hardware doesn’t see them, and nor does Windows.

When I played with it after you convinced me, every change (RAID-on, RAID-off) had the warning: any data will be lost.

@Vael_S

So the 2TB Mirrored drives would be…

/ 32 GB EXT4 (LUKS if you want)
SWAP (Depends on how much RAM you have, you may not need this)
/var/lib/qubes * EXT(X) (LUKS if you want)

Great !
LUCKS FDE.

• 32 GB EXT4 (or ZFS?) for /
• 16 GB EXT2 (or ZFS?) for /tmp
• 32 GB Swap (fallback)
• 100% EXT2 (or ZFS?) for /var/lib/qubes which will contain /vm-templates; /vmapps … and ?
  So I would have to backup this partition and if I have to re-install Qube, I will just re-attach (mount at install) et voilà !

@Vael_S

One password for both if that is what you want, or else use 2 different passwords for the LUKS.

For as long as they are saved in the usb key, it doesn’t matter much how many.

I’m feeling excited, it takes shape ! happy me
Even knowing I still have a long way … once up and running, I’ll have to transfer files, transfer bookmarks, setup access to my NAS, install my VPN (I guess Proton GUI doesn’t work) and so many other things … still smilling !

Note to self: Buy a spare 2GB usb key to make a copy of the first.
