zfs

Hello, Yesterday i discovered by a complete coincidence that one of the drives in ZFS pool has completely failed without any prior notice. by a complete luck i want to check something in ZFS tab and i saw one of the pools is degraded. i go today a new 4 TB HDD and installed it, then i ran this...

Dear Proxmox Community, I have a project I wrote back in 2021 I'm re-writing with Proxmox in mind. I met a local business owner who hosts his servers on Proxmox, and he sounded interested when I mentioned I had compiled ZFS modules inside a kernel, so it sparked some interest in me to...

Hey Guys, I have scoured through the forum to try and answer my question with no success... I have 3 PM nodes running windows VM's with the storage being ZFS backed, with thin provision enabled. I noticed the 1 ZFS array reporting 17TB used, but in the VM there's 20TB storage assigned, but...

Hello, I am in the middle of trying out Proxmox for the first time. My old PC used to be Windows 10 which had 4 Hard Drives running as a Zpool, accessed by Windows. It was a pain to get ZFS to work for me using OpenZFSOnWindows, but it worked. The Zpool stored a large quantity of games from...

[TL.DR]: RAID card firmware bug seems to cause a non boot issue on Kernel 6.8.4-N-pve, works on 6.5.13-5-pve. Any ideas on how to fix? Today I have done a lot of troubleshooting for one of my Proxmox servers. It started when I was rebooting the server after some updates. Suddenly it wasn't...

I have a Dell R530, I recently switched from using RAID5 disks with the built in raid card to HBA mode and using ZFS. Before when I was using LVM, my sabnzbd could max out my connection (between 120-150mbps), however after switching I'm only hitting between 5-30mbps consistently. sab reports...

Hello, I have 3 basically identical systems I’m having put together in a cluster. 2 out of the 3 have the same amount of storage but 1 of them has only half the amount. I want to make everything zfs and I am using intel or micron enterprise ssds. With zfs would I be able to slowly upgrade the...

I have to get on an airplane in order to visit my servers. Or use remote hands. You know how that can go. So, I'd rather not _need_ somebody visiting my servers. Or at least as little as possible. And some of its old junk. So it dies. Enter the spare disk conundrum. It's easy to find ZFS...

Hi guys, since I'm still at the beginning with proxmox (coming from unrai*) I'm wondering about the right disk layout. I have quite a wild growth concerning my hard disk landscape and wanted to ask if a ZFS makes sense or rather LVM? How could a possible ZFS make sense with the disks? I also...

I have a proxmox ve with a single ZFS, named zpool. Inside that proxmox ve node, I have a privileged lxc container with PBS installed via proxmox scripts. When I go into the PBS into storage, I don't see the ZFS storage and I get this error: Bad Request (400) command "zpool" "list" "-H" "-p"...

Hallo zusammen, ich lese zwar schon geraume Zeit mit und habe zahlreiche Hilfestellungen gefunden. Jetzt aber habe ich mich registriert, da ich nicht weiter komme... Ich möchte von meiner Synology Rackstation umsteigen auf Proxmox und die Sync nur noch zur Datensicherung nutzen. Dazu habe ich...

I am observing some very high (>40%, sometimes 80%) IO Delay on Proxmox VE 8.2.2 with pve-no-subscription Repository. Looking at some Posts over this Forum, this may be due to not using Enterprise-Grade SSD, although to be honest I don't necessarily "buy" this justification. I am using Crucial...

Currently PVE runs on 256GB NVME M.2 drive installed on PCI adapter. I've purchased Intel HPE IBM P3600 1.6TB HHHL PCI-E NVMe and I would like to install it and replace system drive. My plan is to remove current drive and connect it via USB3 (adapter) and put in empty PCI slot a new drive...

Alright, super noob here to bear with me. But this is my backup sever that's also serving as my practice server before migrating everything to it from my truenas server. I just need to have my entire TANK visible on SMB of which i'm following this youtube tutorial and i'm good up to the 12:37...

The documentation is clear on the command needed to replace the failed drive after the new one is installed: zpool replace -f <pool> <old-device> <new-device> However, I am unsure of what exact device name to use. The output of zpool list -v and zpool status both show device names that are...

Hi@all, I recognize a wire behavior / issue with my pve installation. My servers running most likely the same both have an Gigabyte MC12-LE0 with 32GB RAM. One server has an AMD R5 3600 and the other one an AMD R7 3700x. I installed pve on a NVME SSD on the server with the R5 3600. On the...

I have 64 GB ram in my server. As ZFS is configured to utilize maximum RAM, I tried to reduce with following config in /etc/modprobe.d/zfs.conf to around 8 GB options zfs zfs_arc_min=8388608 options zfs zfs_arc_max=8388608 but still zfs was using 28 GB.

running a very simple set-up with Proxmox on ZFS I'm looking to have snapshot of everything in /etc and other select directories. Essentially / without rpool and subsequent volumes. Since df -h shows mountpoint to be /root/RPOOL/pve-1 / i tried: zfs snapshot -r rpool/ROOT/pve-1@may2024...

hello, I'm running an opnsense firewall guest and filesystem is ZFS, this the only "production" instance right now i have disabled some ZFS features on the guest already just wanted a confirmation that this is harmless: checksum compression encryption sync xattr=sa also should i disable the...

I am currently planning to migrate to Proxmox, but would like to find out some important things before I actually take the step. Before I ask my questions, I think it is best to describe my setup/requirements: I don't run many VMs, but a few with high IOPS and consistency requirements, as I run...
