btrfs

I just did this (and things appear to be working well) so I thought I would share. Feel free to provide critical feedback. Also full disclosure I did get hints on this from Proxmox support but they couldn't provide assistance as I don't have that kind of license (but the hints they gave were...

I get weird situation Proxmox is installed on btrfs raid of 3 USB flash drives I have two additional btrfs raids on 2x18 TB and 2x15TB where I store data I have NVME where my images are When I start a vm from NVME for some reason my unrelated 15TB and 18TB btrfs raids disappear, lsblk does not...

Ok, I had BTRFS up and running just fine. Then I decided to add a cache SSD using make-bcache -C /dev/sdg but eventually worked out that this would not work as a caching disk needs to be added at the time of creating my BTRFS RAID10. But how do I safely remove /dev/sdg? I'm running Linux...

I am making my first steps with PVE on a btrfs filesystem. When trying to set up a backup location it appears that @ in a file path is not accepted. I get the following error: illegal path for directory storage: /media/raid/@data2/backup (500) While not a requirement, @ is often used to signify...

I am migrating my server from Arch to Debian/PVE. Given that there are quite a few Docker services to migrate, I will dualboot until I successfully moved all services. What makes matters a little non standard is that I use systemd-boot and btrfs, which is why I thought I'd double check here...

Hi, we have encountered a strange situation: Running: 1. PVE 7.4.3 2. Partition /dev/sdb1formatted with BTRFS 3. Partition /dev/sdb1 mounted at /vol/data on host 4. Storage added: `pvesm add btrfs data --path /vol/data ; pvesm set data --format raw` 5. Unpriviledged LXC container created with...

Hello, i can't seem to be able to create/move a container volume on the Btrfs storage type. I get the following error: btrfs error: open3: exec of btrfs -q subvolume create -- /mnt/nfs/nvme_btrfs/pve/images/104/vm-104-disk-0 failed: No such file or directory at /usr/share/perl5/PVE/Tools.pm line...

For better decisions according filesystem choice I thought it would be a good thing to see the possibilities. filesystem XFS BTRFS ZFS Compression with VDO layer inline / offline inline Deduplication offline inline / offline inline Metadata extern yes no yes, special device...

Hello, I installed PVE 7.3 with a BTRFS file system on a small system (old Thinkpad T520 with an SSD for the system drive, and two HDDs -- the latter are directly formatted in BTRFS and exported to a Rockstor NAS VM). The performance so far has been very good. I noticed that the installer...

Hi, I'm familiar and very happy with BTRFS on my Linux desktop. I'm totally new to Proxmox, however. I have the newest 7.3 version installed on a Thinkpad T520 with an SSD and a HDD. I want to put VMs on the SSD, and use the HDD for NAS-style storage. I installed Fedora Server 37 successfully...

Hello, I have a VM with too much space allocated and am trying to shrink it's disk from 200G to 100G. Filesystem of VM is BTRFS and of Proxmox ZFS. Steps I've done: 1) Boot into gparted and resize the btrfs partition from almost 200G to 95G (used partition space does not exceed 100G) 2)...

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...

Hello, 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 Then I...

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...

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...
