Question about local storage and resizing

[fleon]

On a default Proxmox 4.2 install, you get two storage containers:

local: size 94.37 GB, content vzdump backup file, iso image, container template
local-lvm: size 900+GB, content disk image, container

If i want to create a virtual machine, it only allows me to install in local, which is very small, therefore pointless.
Shouldn't virtual machines go inside local-lvm? Am i overlooking something?

The machine has 2 hdd sized 1TB each, and the other disk (sdb) wasn't touched. So i looked at http://pve.proxmox.com/wiki/Extending_Local_Container_Storage and i did the following:

• deleted all partitions on dev/sdb
• created one big partition type 23 linux lvm (NOT type 8e, that doesn't exist)
• pvcreate /dev/sdb1
• vgextend "pve" /dev/sdb1
• lvresize -l 446439 /dev/mapper/pve-data

Everything worked, but the last step in the guide is to actually resize the filesystem. But if i do df-k no /dev/mapper devices are shown, it's rather called /dev/dm-0:

Filesystem 1K-blocks Used Available Use% Mounted on
udev 10240 0 10240 0% /dev
tmpfs 1612040 9044 1602996 1% /run
/dev/dm-0 98952796 1969196 91934052 3% /
tmpfs 4030100 43680 3986420 2% /dev/shm
tmpfs 5120 0 5120 0% /run/lock
tmpfs 4030100 0 4030100 0% /sys/fs/cgroup
tmpfs 100 0 100 0% /run/lxcfs/controllers
cgmfs 100 0 100 0% /run/cgmanager/fs
/dev/fuse 30720 16 30704 1% /etc/pve

If i do resize2fs /dev/mapper/pve-data it says invalid super block or something, and if i try to do it with /dev/dm-0 it says it already is updated.

Can this guide get updated?

It only allows you to create VMs on local-lvm, which is big.

sorry but i see the exact opposite behavior. Please see the attached screenshot.
I can only choose local, not local-lvm to install

whoops, i understand the issue. the screenshot i attached is only to select the OS, which only allows you to choose local. When i continue to the hard disk section i indeed see local-lvm.

Could you explain what i am missing after adding the second drive? As you can see in the screenshot, the GUI shows 1.7TB available, but df doesn't show it. I am afraid the manual was made for an older version.

Also, i would rather use the second drive as a software RAID. Is RAID supported when installing proxmox from the ISO or would i have to add proxmox to a debian install in order to do custom partitioning as http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Jessie says?

you resized the lvm-thin pool (btw, without resizing the metadata).

but df doesn't show it. I am afraid the manual was made for an older version.

df only shows mounted file system space usage (not lvm-thin pools).

Also, i would rather use the second drive as a software RAID. Is RAID supported when installing proxmox from the ISO or would i have to add proxmox to a debian install in order to do custom partitioning as http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Jessie says?

We recommend to use ZFS if you want software RAID.

i used the wiki article mentioned to do the resizing. The article doesn't even mention anything regarding metadata, i followed the guide verbatim. It is obvious the article was made for an older version and lot of changes where made regarding LVM and storage, that's why i am asking for clarification.

How do I resize the filesystem and metadata?
