btrfs

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...

Hello Forum, 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...

HI, May I know if it is possible to install proxmox backup server with btrfs, if so, any documentation for the same? Thank you

I see that BTRFS is in 7.2 and still listed as a technology preview. Is there an estimated VE version when this will be stable for production use?

Hi, 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). HW: CPU Intel Core i5 4460 (4c/4t) RAM 16GB 8x SATA3 ports (2 on the mobo and 4 on a...

Hello, what do you think about BTRF in a production server Raid 1 or Raid10 ? Some one use BTRFS RAID5 or RAID6 ? ( I'm reading that is not stable ..) Thanks!

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. However on...

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...

Hello, 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...

Hi there, 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...

Hello! 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? Best regards,

Hey Guys, new year, new challanges. This year i picked filesystems and after 3 weeks reading documentation, tutorials and best practices I'm just running in a deadend. I picked an existing power optimized server with 16 GB RAM, 1x 250GB nvme SSD (Proxmox+VM), 1x 256GB SSD SATA (Cache/Log), 2x...

Hello everyone! I have proxmox home lab, and now I try to choose filesystem for my virtual machines. I will run Windows VMs and I need better filesystem for that. I setup Windows VM with this config: agent: 1 balloon: 0 bootdisk: virtio0 cores: 4 cpu: host memory: 4096 name: Test-IOPS net0...

Hi there, I have been searching the internet for a couple of hours now and so far come up empty handed. I would like to create some containers and use Docker in them. I have this working by tweaking the /etc/pve/lxc/CTID.conf for the containers like so: lxc.aa_profile: unconfined...
