Installing Proxmox in ext4

[kirelgt]

Hello there:

I use ssd on two physical servers I have, and I really want to use proxmox because I think is one of the best and easiest to use but I am using SSD and "TRIM" is a must.

My question is:
Is there any way during the installation to tell proxmox I need to install proxmox in ext4, or I have to convert from ext3 to ext4 after installation is complete.

Is it there any work around? How can I get "TRIM" in proxmox.

Hi,
normaly it's enough to open one thread

One possiblity is to install proxmox ontop of a debian lenny (see wiki). You wrote, that you use only kvm - this is good, because there are issues with openvz and ext4...

I wish it was that easy, but every time I try to convert the file-system from ext3 to ext4, it gives me a problem. I wish I could install proxmox with the SSD, but it is starting to become extremely difficult to be honest. And a SSD without TRIM in a server is just no gonna work.
Any help will be appreciated.
Goal: Install proxmox with SSD in which TRIM is enable and working.

Sure?
Of couse is TRIM usefull, but i think not that you can't use SSDs without TRIM.
What kind of SSDs do you use (there are some scrap on the market)? But with good SSDs you should get good values (like OCZ vertex 2, Intel X25E).
I should get some SSDs next week (or one week later) and i can test a proxmox installation with this disks.

there is not need to convert from ext3 to ext4 if you just install Lenny with ext4 and then on top Proxmox VE.

Hello Tom, hey you say this

"there is not need to convert from ext3 to ext4 if you just install Lenny with ext4 and then on top Proxmox VE."

I tried to install debian in every possible way, looking for a way to install it using ext4 but I just can't see it. The only choice it gives me is ext3.

Please if you could direct me on how to do it.

By the way the SSD I use are 2xC300 128Gig, 1xOZC Vertex 2 120 Gig.

Thanks in advance.

you are right, the lenny installer does not support ext4 - sorry for misleading. lenny backports kernel supports ext4 but I do not know a method or a installation media using the backport kernel. so converting is the only way so far.

the upcoming Proxmox VE 2.x series will be based on Squeeze so the problem will be go away in future.

Thanks anyway.

Still I have a question. Do you know a good article or site that tells me how to upgrade de linux kernel in proxmox. Actually it uses the 3.6.32 and I will like to install the latest. I have read a lot places and always problems with the upgrade.

I need the linux kernel NOT the proxmox kernel.

Thanks in advance.
