Hi!
When trying to setup Proxmox on using ZRAID10 on 4 1TB disks i get this error:
Warning: mirrored disks must have the same size. Please fix ZFS setup first.
So I installed the Proxmox on an extra 500GB hdd and then added the 4x1TB using this:
zpool create -f -o ashift=12 <pool-name> mirror <device1> <device2> mirror <device3> <device4>
from here https://pve.proxmox.com/wiki/Storage:_ZFS#Create_a_new_pool_with_RAID-10
The system is working and the pool can be seen in the GUI size is 1.8TB but if i do zpool status It shows state of all disks ONLINE and READ, WRITE and CKSUM is showing 0 on all disks.
So I figured this is ok, if there is an error it should showup here. I created 2 VM (simple ubuntu installs) and if both of them are running everything slows down by 99%. Meaning a login after inputing the password takes 2 minutes.
Is the problem comming from the initial problem of all disks not having the same size? All of the 4 disks are 1TB WD BLUE, but one of them is NEW, the other 3 are about 3 months old and when I check them in DLGDIAG, the new one is 1kb different in size from the others.
What kind of a setup would you recommend in my case?
Thanx for your help!
