Checking the Local Storage, Root, Swap status

[jagan]

Hi team,

i am new to proxmox , currently i am using proxmox 3.3 version. proxmox installed on /dev/sda (ssd-120gb) and it has 2nd disk /dev/sdb(hdd-1tb). i am using 2nd disk as lvm storage to store VM images. Now my queries are

1.How to check the storage status (free,usage) of ssd, is there any gui package/app to monitor status of PV,VG&LV . in cli with fdisk and display cmds we can n't see the free&usage space.

2. After installation of PMX on ssd it is split-ted into 3 partitions (root,swap,data) how to check the free and usage space of these 3 partitions. And what is the min. required or recommended space for root/swap. is there any guide line for root/swap?

3. Where to see the file system type / partition type of logical volumes? Both both SSD(pve) & HDD(lvm).

4. I got some 60gb of data partition from SSD to store images/files. i am installed a VM using 30gb of space but in gui it is using total-60gb,usage-10gb,free-50gb. And it is allowing me to create a VM with 200gb space how it is possible.
How to know the real space used by a VM while it is operational ?

I am getting little bit confusion on Root , Swap and SSD(local storage) utilization. In gui or CLI i am unable to understand total/usage/free space values. Please anyone can help me,

Thanks in advance.

Hi team,
1.How to check the storage status (free,usage) of ssd,

you can ssh to the system

ssh root@serverip

Once in the terminal run:

df -h

you will see something like this

Hi, thanks for quick reply,

what is the guid line for root and swap partitions. what is the recommended space for root and swap in PMX 3.3

Check here for information about the GUID partition table http://en.wikipedia.org/wiki/GUID_Partition_Table

Regarding size question, I don't these are officially documented anywhere Post #5 from this thread is a pretty good answer.
