expand the SWAP memory in PROXMOX

[tirk]

and I would like to be able to expand the SWAP memory in PROXMOX

you need to repatition your disk or add another one.

I have little RAM and the SWAP memory in PROMOX is the same as the RAM it would be to duplicate the PROMOX SWAP memory.

 

[UdoB]

(For me) relying on swap on a PVE host is a really bad idea. Real RAM ist always the most scarce resource...

You might want to search for "zram" to get some percent more headroom...

BTW: you did not tell us anything about your system. How would you expect any helpful hint specific for your situation???

 

[LnxBil]

Then get more RAM. I normally run my systems without physical swap, just with zram as @UdoB said.

 

[tirk]

Prefect, thank you very much, I will try it and see about the ZRAM.

another question I have is, I have PROXMOX8.2.7 installed on a 480GB SSD with the /dev/sda3 LVM partition is 319GB, how can I resize the partition instead of 319 being 479GB? thank you so much

It's LVM so it does not matter. Just create a volume of the size you want.

I don't know how to do it

My mini pc only has a ddr3 module and I have 8gb.
with ZRAM it worked very well

They thow it out and buy better ram or reduce your load. Swap is never the answer and should not be used frequently on a hypervisor.

No, you already have your physical volume and your volume group. You just need to create a new volume as described in the link I gave you or resize the one you already have, where your current swap is located.

As you said, you have currently 16 GB or RAM and also 16 GB of swap and it is not enough. I don't see the point in getting even more swap as others also pointed out.

I would like to change the size of current exchange and I don't know how to do it
without information being lost

lvresize --extenes .100%FREE --resizefs /dev/-volume group name-/root ????????? I don't understand how to do it.

 

[LnxBil]

As already said, you already have a swap device in pve/swap with 7.25 GB ... fix your problems concerning the memory load and do not increase swap.

 

[esi_y]

Strange, is this is really about repartition / extending anything? If the OP just wants more swap, why not add extra, even as a file?

 

[tirk]

As for the ram, this already solves it, thanks

 

[tirk]

I just need to know how to make an LVM partition or resize the one I have to accommodate the free 160GB I need to know how he creates

Why do you want to resize it? If you don't want more swap, what do you want? You can just create VMs on the LVM, and PLEASE read the links we gave you. Everything is in there.
