Maximun Size of Volume or Disk that can be assign to Proxmox

[kirelgt]

Hello everyone, I have a SAN system in which I will store lots of data, the question is I am sure that I will use much more than 2 terabyte of data and I use a program called glusterfs that will not allow me to add more than one disk for storing, the only way out is to have a disk that can hold more than 2 terabytes of data.

Can someone please tell me the size limit promox will allow to assign to a VM. In the case is less or equal to 2 Terabyte, what other choice I have.

I'm using up to 10 TB of Storage. so far no problems

Thank you for your reply. My real question is the following, a specific volume called volume3, how big can this volume3 be?. I know there is with VMWARE a limitation to 2 Terabyte per volume.

I just used google and found the following answer, I dont know if true:

• For 32-bit CPUs on 2.6 kernels, the maximum LV size is 16TB.
  
• For 64-bit CPUs on 2.6 kernels, the maximum LV size is 8EB. (Yes, that is a very large number.)
• For 2.4 based kernels, the maximum LV size is 2TB.

Sorry about asking you again, what will be the maximun size that can be assign to a VM.???

That depends on the underlying storage technology you choose.

Thank you for the reply, would you mind telling me what do you mean by "underlying storage technology".

I have a SAN, and I normally create the volume in the SAN and assign to the proxmox machine using iscsi. My question is if I create a volume that is 3 terabytes big and assign to proxmox. My main goal is to assign this 3 terabyte volume to a specific VM. Will I be able to assign this volume to the VM..

Thank You in advance.

yes, that should work without problems.

I tried this already without any luck. Here is what is happening.

I have an adaptec card with 8 HDDs of 1.5 Giga each. Because I cannot install proxmox into a partition larger than 2 Tera, what I did was created a RAID1 of 2 HDD, and the other 6 Disk created a partition of 4 Tera. Now the concern is the following. I need to assign this 4 Terabyte partition to specific VM. When I assign the 4 Terabyte to the VM the VM only sees 2 Terabyte, what can I do regarding this problem.

Thanks in advance for your response.

what VM did you try? should work.

VM type, if you meant OS I used ubuntu LTS 10.04
