Disk Management in Proxmox while installaion

[Upendra Dhoble]

hi Support,
I am new to proxmox , and installing 4.1 on server class machine.

I do have 5 HDD with 465 GB and 1 with 1 TB , I did successfully installed proxmox however I am not able to locate the disk in web GUI

Questions
1 ) what is best approach to install Proxmox on high configuration server , like how we can use it for best performance

3) how to design swap or /var partitions

here is output for my current disk configuration, kindly suggest

#lsblk

does it also support teaming of LAN card for network performance boost

 

[LnxBil]

It's Linux, so everything is possible :-D

The Proxmox VE Installation is a rudimentary installation that is built for machines that have either hardware raid (one disk, normal for "server class" hardware) or use multiple disks with the same size to use ZFS RAID. If you do not want to it this way, please change it after the installation or install Debian Jessie and upgrade to Proxmox VE afterwards.

 

[Upendra Dhoble]

ok let me try

 

[Upendra Dhoble]

Hi, here what is my setup
There are currently 6 HDD, each 450 GB

I installed Proxmox on one disk , and can see the other disk when run lsblk command

root@pve:~# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 465.8G 0 disk
├─sda1 8:1 0 1007K 0 part
├─sda2 8:2 0 127M 0 part
└─sda3 8:3 0 465.7G 0 part
├─pve-root 252:0 0 96G 0 lvm /
├─pve-swap 252:1 0 15G 0 lvm [SWAP]
└─pve-data 252:2 0 338.7G 0 lvm /var/lib/vz
sdb 8:16 0 465.8G 0 disk
└─sdb1 8:17 0 465.8G 0 part
sdc 8:32 0 465.8G 0 disk
├─sdc1 8:33 0 1007K 0 part
└─sdc2 8:34 0 465.8G 0 part
sdd 8:48 0 465.8G 0 disk
└─sdd1 8:49 0 465.8G 0 part
sde 8:64 0 465.8G 0 disk

Now I want to create the volumes of 900 GB is ( can combine logically two disk) I followed the below steps

pvcreate Test /dev/sdb1 /dev/sdc1
created a group using vgcreate Group name

now I was able to see the group in Proxmox Web Gui , however it doesn't show any disk or volume associated to it.
what I am missing here

I can see the aggregate size for each ( I did combine two disk for each volume ) Volume but , can see the mount point

Thanks
Upendra

Why not combine all disks in a real RAID over all disks, this is best for you current confusion with volumes, mountpoints etc.? You will most definitely not run your disks in RAID-0 mode.

 

[Upendra Dhoble]

let me configured the raid and see if I can able to mount and make visible in Proxmox

 

[LnxBil]

You should configure all disks in one raid array and reinstall Proxmox VE on it. Then you'll have a better setup with easier storage integration.

 

[Upendra Dhoble]

does it affect the performance , means I can create multiple RAID 5 disk groups and create volumes and mount them separately

 

[LnxBil]

In general this is the rule of thumb:
The more disks a disk array has, the better performance it can get. If you only optimize for speed, you could use raid10, but with 146 GB disks I doubt that you could only optimize for speed, so I'd suggest a hardware RAID 5 over all available disks.

 

[Upendra Dhoble]

Thanks for answer.

"Performance" is an open ended criteria. define your use case, establish the I/O requirements (normal and max). Also, performance may not be your primary driver, what about fault tolerance? Once you establish your criteria, a good place to start is here: https://pve.proxmox.com/wiki/Storage_Model
