New install Raid(1) does not seem to work?

[Dariusz]

Hello
I'm setting up new proxmox after years of using old one. So new version new problems :- )
I Want to have HDD redundancy on OS just in case one of them dies, I can quickly swap it & keep rolling. As it will be my work-home-office server...

I have 2x500gb Samsung disks. The idea is to use them as Raid1 - main OS for Proxmox + maybe 1-2 critical VMs.
The Rest of the Disks will be hocked up to TrueNas running in VM and that will be used for other VM's.

In any case, I've hit setup & install & Raid(1) & next next/ and wohoo I'm in WebGUI!
BUT
Summary gives>
224.00 KiB of 896.69 GiB
Which look a bit wrong as I should see 465gb max...
So... I'm a little confused...

I also tried Hardware Raid in bios, but Proxmox did not see that volume at all and he just saw individual disks...
I've installed the Proxmox 3x now as I though I "miss clicked" but no luck...

Any idea how to solve this issue?
Thanks!

What raid1? ZFS? In case of ZFS see the outputs of zpool status -v and zfs list -o space.

Hey
There is only 1 raid(1), the other one is raidz(1) and BTXXX raid(1) I think during install.

I think you are right


It seem to be mirrored,
I also noticed that each time I create new "Storage" in datacentre, it just adds up 465gb to summary... so that is somewhat weird...
In any case, it seems to be workign! Wohoo!
Now I just have to figure out where would I see alerts if one of the disks broke!

By configuring zfs-zed+postfix or external monitoring tool.

After having been a user of an older Proxmox setup for many years, I think it would be prudent of you to understand what ZFS is & isn't.
Its not simply Raid(1). It has many advantages & caveats that you need to be aware of.
I suggest now is a time (freshly installed) for you to read up & research carefully what the ZFS system actually is & isn't. Specifically within the Proxmox environment.
