how to mount second partition or disk?

[artisticab]

Hello,

I am trying to figure out how to mount a second drive or partition so that it is available in the proxmox console for vm's, backups, and storage. I have 6 2TB SATA drives in RAID10 configuration, drive #1 (/dev/sda) is 2.0 GB, drive #2 (/dev/sdb) is 3.8 GB (the rest of the drive). When I installed proxmox, I had the option to choose which partition, so I think it is mounted already? How do I activate it in the console?

Thank you for your help.

Hi,
use the search function - there are plenty posts about this (I have wrote many answers).

Udo,

I have used the search, and have read many posts (before just asking). I will continue to search then...

Thanks,
G

This solution worked the best in my scenario to add the disks/partitions:

First, followed this: http://www.debiantutorials.com/add-a-second-hard-disk/

Second, using the pve web console, go to: datacenter > storage > select "add" folder

"ID" is what you want to name the drive
"Directory" is the folder created in the first step (must include the / ). I used ( /disk2 )
"Content" is what types of data you want


I am still learning, so I thought I would share my results as I hope this helps others.

Thanks,
G

Thanks artisticab, your reply 100x more useful that the well-known members.

Thank you for this valuable post. I have been trying to sort this out for two days and stumbled upon your article and it helped me out. Cheers!!!

For sure it helped much better than a "use the search function".

I hoped a way to do it inside the web-GUI but it seems not possible.
Assigning the disks to a VM or directly to pve for storage still need to be done by command line, a pitty compared to all the GUI can manage !

So I did it like you, like for a standard debian system. Just used EXT4 instead.
Then I disabled the "local" directory which was very small (less than 10Gb)

So now :
Proxmox is running on a SSD 120Gb.
vm are stored on the SSD
backups and iso on a mounted 2,5" hard drive

This is what I needed to do to store VMs on mdadm raid1. I'm running the ve on an ssd and wanted to use mdadm raid1 as vm storage. Thank you so much. If you've been searching like me, just create the software raid per your favorite guide, mount /dev/md0 to /yourpath/raid1 or something similar, and use the content field for disk images. Disable disk images on local. Remember to add it to fstab so it mounts on reboot.

Searching this forum is pretty much useless since all of the answers are staff or greybeards telling you it's unsupported or dumb for x reason rather than offering an answer to your question. Just give me a way to do it, say it's unsupported and I'm an idiot for doing it, and move on.

People learn best from mistakes and figuring out why things failed rather than just hearing "you're wrong do it my way."

I'm looking for a LVM Thin version of these instructions. My system won't start up after doing this so far.

This forum's search and the "manual" (and wiki) on this and other topics are frequently abysmal.

Woohoo! Took me a while but I got it done, pretty new to Linux. Thanks a million times!

Thank you very much for the time and effort you put forth in answering the question. I am new as well and this was the perfect answer.

Thank-you artisticab the procedure worked like a charm. I added a disk to my NAS VM and I was able add the drive with two active partitions.
