Yes, sure! But my situation is I have only one disk 3Tb and one disk 6Tb already. Unfortunaly I can't buy another disk(s) now. I am going to try to make 9Tb storage with these two disk using LVM. Now I reading LVM manuals) There is in Proxmox manual about LVM writen: # pvcreate...

Hello, I finally bought an additional HDD to enlarge my pool size. The new drive has 6Tb capacity. I have pool with 3Tb HDD now. Is any possibility to add this new drive to existing pool to make 9Tb total pool size?

So do you calculate the size to set quota from 2.63T which we see in zfs list ? Now I see in zfs get all mpool that mpool compression on local What is compression = local? May be better to switch the compression type to lzjb or lz4?

I created zfs pool mpool on /dev/sda via web-gui. There is the question about the size of quota to should be set for the new pool. fdisk -l shows capacity as 2.7T, zfs list shows 2.63T - see below. What quota size should I set for mpool? root@pve:~# zfs list NAME USED...

1) So can I mount them in the host and get access to their files in the host's system? 2) What option concerning disks is the better while creating ZFS pool: 1. raw disks 2. disks with created gpt partition 3. smth else 3) Should I make any preparations with a disk before adding it to zfs...

1) About deduplication - can we really use it? I have read everywhere - do not use deduplication... Now I have no budget to buy additional disks to make mirrors. But storage capacity should grow and I will buy additional disks for adding them to the pool as a single disk As I wrote that I plan...

Maybe that it is easier to do with LVM?

I think it is not a problem - we can wait some time) How much time it will get for 1Tb of new disk capacity? Do you mean to do the storage on single disks (not mirrored or in any raidz)?

I did not intend to expand the pool from which the system boots. I'll leave the two NVMe disks that are have used already for rpool as they are now. I have a big SATA disk in my server also and I mean to make a new pool with this SATA disk. For example, spool. Then I will extend the spool by...

Another question - how best to organize such a "growing" storage? That is storage to which new disks can be added so that its size increases and the configuration changes (from a single disk to a mirror or raidz). LVM or ZFS? If we build this storage based on ZFS, then how best to forward the...

I have to make data storage for media files. Total data size will be growing and I will add new disks to the storage as it will be necessary. Now I have only one physical server so disks for this storage will be plugged into the server with the PVE host. And systems in guest VM need access to...

So maybe is better do not to set quotas for rpool/data and rpool/ROOT separately but set only one quota for the whole rpool instead (as 80% from ZFX disk capacity)?

Where is the default storage Local is situated? At rpool/ROOT? The backups of VMs are at Local storage. I think 20G is not enough for it

Yes, I understand)

Does it make sense to set the parameter vm.swappiness to less than 60? For example, vm.swappiness=10?

OK, thanks a lot! I got it) May be you can help me with new trouble https://forum.proxmox.com/threads/network-device-entered-promiscuous-mode-blocking-state-disabled-state.104523/
