zfs

I have a couple of nodes, and they're for homelabbing. I'm learning system administration with these. They both use ZFS. One is a PowerEdge 730XD with a PERC H730 RAID controller set to JBOD and a few pools in different configurations (2x Stripes and a mirror), and the other is a ThinkCentre...

Hi, I'm well aware that zpool list and zfs list are reporting different numbers, because zpool looks at the raw data on disk while zfs reports logical numbers. However my numbers are so weird, I cannot take them for being correct or making sense. I have two pools 'data' and 'vms' and both are...

Hi I'm trying to configure shared iSCSI storage for my 3-node Proxmox cluster. I need all three hosts to access the same iSCSI storage simultaneously for VM redundancy and high availability. I've tested several storage configurations: ZFS LVM LVM-Thin ZFS share Current Issue With the ZFS share...

Hi, I'm adding some HDDs to my home server and wanted to double-check my proposal makes sense before I hit go. Please can you advise if this seems sensible or if I am barking up the wrong tree? Hardware: HP EliteDesk 800 G3, i7-7700 CPU, 32GB non-ECC RAM, 1x512GB NVME SSD 2x4GB Seagate Exos...

Hi everyone, I have a ZFS RAIDZ (3 disks) setup that was created using whole disks (no partitions). Unfortunately, I accidentally ran the following command on one of the member disks: sgdisk -Z /dev/sdb This wiped the partition table and GPT headers. Now ZFS doesn’t recognize the disk as...

Occasion: Actually, my one wanne build such a boot environment on BTRFS Raid1 because of my experience with timeshift in the desktop field, but while my experimentation the question comes up, of course, is this possible with zfs. And when one research the web for zfs snapshot boot menu solution...

Hi folks, I've been using ZFS on Proxmox for a few years now, ever since I got my first drive shelf & HBA card I've had issues with ZFS suspending pools randomly on startup. Anything that relies on the pool tends to hang, requiring a restart to fix. When I try to shutdown, the whole system...

I had proxmox running on a zima blade, with two HDD on RAID1 (zfs in proxmox). It stopped working and the pool disappeared. I tried to check if either of the drives could be read for the data on my pc , but it turns out, both drives have failed (it spins but doesn't get detected by the system)...

Hello all, we are configuring a Dell server for ProxMox with ZFS (no Ceph), and I wonder what I should select in terms of Controller. Prefix: I know that ZFS is not compatible with HW RAID, and we do not want to do ZFS with HW RAID. However, on one hand, we also have loads which we want to put...

Hello all, I'm sorry if this was discussed previously, just the search terms ZFS, storage, rpool didn't lead me to the info I am looking for. My past experience is using LXC and incus separately, so perhaps I am misunderstanding how terms I believe to know are used in proxmox. I have a PVE on...

Does PBS actually make use of atime? Or is it just inherited because of ZFS upstream? TrueNAS disables atime by default for performance reasons.

2 nodes, 3rd node does not have access to ZPool, it is just a tiebreaker node for quorum. No snapshotting, backups are handled by Veeam to their own hardware (in other words, no backups in the web-interface of ProxMox). Everything migrated from a HyperV computer, where the 7TB was...

Hallo zusammen, ich verwende PBS 3.4.6, der Backup-Pool ist ein raidz2-Pool bestehend aus acht Festplatten (nicht ganz das empfohlene Setup, es erfüllt aber seinen Zweck und spielt für das Problem eher eine untergeordnete Rolle). Nach einem Reboot mit Kernel 6.8.12-15-pve wurde dieser...

Hi all, I am looking for some guidance on the clean removal of a node from Proxmox cluster. What I did so far: - Created cluster named 'Test-PVE' - Added three nodes (proxmoxVE01-03) to the cluster - Verified cluster manager status and nodes via 'pvecm status' and 'pvecm nodes' -> all three...

I am trying to use zfs send to duplicate and entire pool between 2 nodes and I am getting very slow results. Any help would be appreciated. Hardware (both nodes identical): HPZ840, Dual Xeon 36 core, 256GB ram Asus M4 with 4x 2TB WD SSN7100 in RaidZ NIC Intel X550T2 10Gbe Testing pool speeds...

Hi, I have two VMs which have cloudinit drives, which are failing to replicate over that drive, when a replication task is created, other VMs with cloudinit drives are replicating over fine but these two aren't. Granted those other VMs replication tasks were created months n months ago. Trying...

Hi there, I am running Proxmox on a dedicated server with OVH, and under high disk load, the whole system seems to be taken out. Sometimes just for a few seconds, sometimes a few minutes, and more often than not completely requiring a hard reset of the system. When this happens, I can't see...

Hello, I installed Proxmox VE using two disks with ZFS RAID1 (mirror) for lab testing From my testing: If I unplug or fail disk 2, the system still works fine and Proxmox is accessible. But if I unplug or fail disk 1, the system will not boot and Proxmox becomes inaccessible, even though disk...

Hey everyone, I'd appreciate some advice on properly partitioning and configuring my Proxmox VM/CT & storage server. I want to make sure I'm following best practices before I start deploying VMs and containers. Here's what I'm working with: Hardware Setup: AMD 3950X with 64GB RAM...
