Hi, so I am planning to upgrade my homelab to 10GBe and want to move my VM storage from my ESXi host to my TrueNAS Scale host. I am planning to make a new pool comprised of older Enterprise Sata SSDs, since I want the VMs to be as responsive as possible and saturate the 10G link. I will also...

I moved a ZFS pool to another server. Pool imported with no errors using # zpool import pool0 pool0 contains both encrypted and unencrypted logical units. Encryption keys were restored to /local/keydata on the new server (plus a copy on another location). Unencrypted LU's were imported...

I have a homelab rack setup with a few servers and my HDD NAS server is having an odd issue and I can't easily pinpoint if the issue is the controller, the slot, or the HDD itself. Problem The same HDD in drive bay 1 will be removed from the system. I don't see it drop in system logs but I see...

I've decided to make the jump from HDDs to SSDs for my main storage and now i'm wondering if I needed to buy the backplane that bought. I have a supermicro CSE-846 24 bay case and it had the BPN-SAS2-846EL1 backplane. Right now I'm using 20 3tb spinning rust sas drives but I have bought 20 2tb...

Hello, I'm trying to migrate from tiered Windows Storage Spaces volume where I have 2 HDD's (3TB and 4TB) in a slow tier and a 512GB SSD in a fast tier. Windows is, and TrueNAS will be, virtualized with disks connected to a passed-through HBA. Performance is fairly important as I have VM's that...

I started down this path over a year ago and play with some stuff at work (a bunch of really old hardware just laying around). This is the design for my new home server to replace my X299 HEDT computer that currently just hosts PLEX. It could have a lot of capability but was my old gaming rig...

I'm currently using FreeNAS for iSCSI ZFS block storage for my ESXi server. The FreeNAS box is getting old so I'm looking for a replacement. I'm not currently using any of the other FreeNAS features besides ZFS and iSCSI. I was initially planning to upgrade the FreeNAS box to TrueNAS Core or...

While transferring a mix of files ranging from large (4gb+) and small (a few hundred kb) over a 25GB connection, I notice that speed would spike to anywhere between 600MB/s~1.2GB/s and then slows down to 9mb/s rather than more or less stay at a consistent speed. This speed pattern would repeat...

So I have always wanted a ZFS HA SAN for the house, and a project at work introduced me to OSNexus QuantaStor, as well as their amazing CEO/CTO Steven Umbehocker who ended up handling my sales call during December a year or so ago while his sales staff was I guess doing holiday stuff. After...

We had a physical problem in our backup server (we suppose an electrical shock due to the thunderstorm). The system is Linux Debian on a disk and the storage in on a two 4 TB disks RAID-1 ZFS (ZFS On Linux) pool. The first symptom we discovered was a frozen system. After we had multiple erratic...

This is about ZFS Filesystem and the (not) need to stack multiple layers of ZFS and snapshots, but made to utilize all the functionality from ZFS napshots on the proxmox host. to achieve this fabulous glory of software-engineering i utilized this projects: cv4pve-autosnap and Zamba Fileserver...

Hello, we are working on new ZFS GUI called Poolsman (www.poolsman.com) and would like to invite you to join our Early Access Program (EAP). Poolsman is intended to give an easy, graphical way for managing ZFS on commonly used Linux systems (including Debian, Ubuntu, RHEL, Rocky, OpenSUSE...

Good day to all. I am trying to setup a new trunas system. I'm running an r720 server 96g ram. Hba card (sorry forget off hand which one) and 5 netapp ds4243's. Each netapp shelf is populated with 24 600gb 15k sas drives, and OM3 controllers. My plan is to power up only the shelves I need for...

I currently run Proxmox on a DeskMini H470 with an i5-10400 and 64GB DDR4 (non-ECC). I have about a dozen VMs/CTs running, with one of the VMs running about 25 Docker containers. The Proxmox box hovers around 5% CPU usage and 60% RAM usage. Proxmox is installed on a Samsung 970 Pro 512GB NVMe...

Specifically, I'm looking at Ceph (via Rook) and TrueNAS Scale (so OpenZFS) between CPUs like Xeon D 1500/AMD Epyc 3000 vs Atom C3000/Xeon D 1700. I can't seem to find anything about using QAT with Ceph/ZFS besides the fact that it's available to use. There is an older thread here about QAT on...

I'd like to get a NAS to use at home as an additional backup destination for several home PCs, besides two cloud backup services I already use. No VMs, no media server, just a another place to archive my data (and Windows OS drives), ideally with snapshotting and ease of replicating (eventually)...

tl;dr I just got an Optane drive. I'm currently running 2 SSDs in mirror as ZIL, I want to remove them and use only the Optane drive as ZIL. How can I do this? My current setup is as follows: Xeon D-1541 8c/16t 64GB DDR4 ECC Registered 6x12TB drives in RAIDZ2 (72TB raw, 48TB usable) 1x512GB...

Hi, I work for a research hospital. I would appreciate any comments or advice for file system and hardware design for a high-end storage solution. We have a few microscopes (running windows 10), each can produce 3-4GB/s of image data that needs to written to the shared storage and to be...

Don't call it a h-- t-- time machine httm prints the size, date and corresponding locations of available unique versions (deduplicated by modify time and size) of files residing on ZFS snapshots, but can also be used to the interactively view and restore such files. 'httm' might change the way...
