Hi, on a fresh install of Proxmox with BTRFS, I noticed that the containers install by default with a loop device formatted as ext4, instead of using a BTRFS subvolume, even when the disk is configured using the BTRFS storage backend.
I'd like to use BTRFS directly, instead of using a loop...
I had a severe issue with OS disk (using BTRFS) and must replace it.
This means I started block copy using dd from old disk to new SSD; I performed the following steps:
1. block copy with dd from old to new device
2. extend root partition
3. resize BTRFS of relevant partition
Has anyone else seen or had issues with local-btrfs. I have tested with every setting I can find. When trying to backup a VM or container that is using local-btrfs. It is not usable. I am talking 8-128kib/s I have adjusted vzdump I have tried no compression. You name it. I move the VM or...
Hi, I am using BTRFS in all of my installations. I wanted to use it as filesystem for virtual disks for Proxmox (I am using 7.2-11). I was able to successfully create BTRFS storage (which seems to be more similar to Directory storage - means I need to mount it separately as it is not done by...
I installed Proxmox and chose the option to use BTRFS in raid 1 configuration across 2 SSDs.
This has worked perfectly fine, but recently disk space is becoming low. I only have space for 2 drives in the case, so I would like to expand/replace these 2 drives with larger ones. I'm...
I have installed pve 7.1 with btrfs mirror using 2 SSD's. During installation these SSD's are /dev/sda and /dev/sdb.
After base Installation I added 3 HDD's with an existing zfs. The device names of the SSD changed to /dev/sdd and /dev/sde.
No problem so far.
To check what is happening when...
Hi All -
I decided to give btrfs a try as my root FS on a single mSATA SSD. Everything seems fine aside from boot times - for some reason, GRUB hangs on the "welcome to Grub!" message for a solid 20 seconds. Grub's also seems slow to respond. Once the kernel is loaded and the initrd is...
I simulate disk fail on the raid1 btrfs which is also my root for proxmox ve 7.1-7.
When one of the disk failed, the system will not boot.
It stuck at initramfs, i am unable to mount the system as the initramfs does not have mount.btrfs
The system will boot normally with both disk exits...
Hello, I'm going to install a new fresh Proxmox server for my homelab and I'd like to ask you suggestions to configure it in a proper way (I've already a Proxmox server I'd like to reconfigure from scratch).
CPU Intel Core i5 4460 (4c/4t)
8x SATA3 ports (2 on the mobo and 4 on a...
While working through the Cloud-Init at https://pve.proxmox.com/wiki/Cloud-Init_Support to create a Template on my PVE7 system that is using BTRFS storage I get the following error:
$ sudo qm set 100 --scsihw virtio-scsi-pci --scsi0 local-btrfs:100/vm-100-disk-0.raw
update VM 100: -scsi0...
I'm a little confused with the documentation. The BTRFS page says
BTRFS will honor the O_DIRECT flag when opening files, meaning VMs should not use cache mode none, otherwise there will be checksum errors. which I understand to mean set the disk cache to anything other than none.
Hi, i would like to use QCOW2 image to my VMs, i am using BTRFS file system in PVE 7, but i found this https://forum.proxmox.com/threads/no-qcow2-on-zfs.37518/ post and there is a good question. Can I use it without loss of performance?
I am playing around with btrfs at the moment. What I haven't understood yet how to deal with degraded arrays:
First I tried to install PBS in a VM, rootfs on ext4, so nothing special. Installed kernel 5.11 and btrfs-progs from backports.
Made three disks and put them into a raid1-array with...
I'm a bit lost on the optimal configuration for a Proxmox Homeserver running Jellyfin and other file and cloud services. I've an Asus C246M WU4 Mainboard with Xeon E2146 CPU. I use two NVMe SSDs in a mirrored setup with ZVS filesystem.
I own one 8TB HDD for media storage which I plan...
I currently have some VMs which are hosted on and run from a shared NFS share by the Proxmox hosts.
I currently use Proxmox to backup (snapshot) these VMs back to the NFS share but this seems inefficient with the reads from NFS -> PVE host and writes back from PVE -> NFS host...
I have a question regarding the content of Grub Menu vs. /boot/grub/grub.cfg.
In my case the content is inconsistent.
And this is causing an issue with booting a BTRFS snapshot, because the
required snapshot won't boot with the options displayed in Grub Menu.
I'm running these software...
Dear all, I want to have urbackup VM and I want to use btrfs killer feature (cross link, offline dedup and so on) with urbackup.
What do you think if I will have zfs (zvol) as my host fs and btrfs as a guest system?
