Storage Setup Advise

[klabacita]

Hello.
I have running v 8.1.x, the server that I have, support 8 HD.
I'm thinking in how to setup the storage, any sugestion welcome.
The idea is to setup 4 Raid1(1/1) and create 1 volume for all our vm's that would run under this server.
Any other recommendation I will appreciated, thanks.

Rotating rust or SSD? If rotational: sacrifice 2 of them, replace them with SSDs and add them as a mirrored "Special Device". Search for this term for the reasoning. (No SLOG and no Cache, except you have a specific reasoning for this.)

Oh..., is it ZFS? I do not do anything else...

you're almost there- instead of 4 individual volumes, make one striped mirror volume. @UdoB point should be well taken- if its 8 HDDs you'd be better off adding 2 SSDs (replacing 2 HDDs if necessary) and use those as your virtual disk storage, and use the HDDs for bulk storage only.

That still isn't answering if those are SSDs or HDDs.

You may need to / it's recommended to install Virtio Guest Tools if you are running a Windows OS. This may help getting the disc recognized. If not, we'd need more info about your setup.

Yes, I saw that picture, please check my recommendation.

not working

not working

Can you provide any more information? It's really hard to help debugging else wise.

• What OS are you using inside your VM?
• Is the disk shown via 'Windows Partition Manager?
• How is the disk you passthrough partitioned?
• What is your expected outcome of passing through this disk? As far as I can tell from your previous post this seems to be a single disk of a raid5 array? (Windows 'Raid 5', mdadm or hardware Raid 5? )

Can you post output of:

lsblk
mount

Okay please see my above post, I added more questions.

 

[Dunuin]

Did you really install all the virtio drivers? You probbly see the first disk (ide) because IDE doesn'T require additional drivers. The second disk (scsi) won't work without the virtio disk drivers.
