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...
So to preface. I'm not going to do this. I'm not running zfs even (maybe yet , maybe ever).
I was going trough the basics and I have questions my regular hangout couldn't answer in a way that wasn't "that's just dumb" . So you're supposed to size your pools and vdevs according to your loss...
tl;dr - I'm running Proxmox 6.4-13 on a system with 2x e5 Xeon procs, 128gb ECC ram, with a rust array of approximately 50tb. My issue is, proxmox continuously kills 2 of my containers for OOM conditions, and I can't for the life of me figure out how to solve this. Oddly, it almost seems like...

The work load consists of generating many files as fast as possible on very fast storage, (RAID 0 of nvme drives) and transferring that data to slow storage for long term storage while minimizing the bottleneck. I'm trying to minimize the time limit for the transfers to long term storage. When...
I'm looking for some advice on partitioning a new system with multiple disks for root on ZFS with Ubuntu Server 20.04. This is the hardware I have:
2 x Intel D3-S4610 256 GB SSD
4 x Seagate EXOS 7E8 8TB
32 GB ECC RAM (planning of expanding to 64 GB later)
In brief, this is what I tentatively...
Hello experts. I'm have recently built a server to be used as file-/media server for myself and a few family members. It will be running on Ubuntu Server with ZFS. I will be using Docker to run quite a few services for serving and streaming. Although I have already built the server I am not...
I have a small server (Debian Buster) containing 2 WD RED hard disk which I have encrypted with LUKS and on which I set up a ZFS datapool with RAID 1.
As the server is not used to frequently I have created a autoshutdown script which checks for services etc. and if the data drives are active...
I'm selling a 3.2TB barely used Sandisk SX350. Current vsl-iomemory4 drivers are available from Snuf's GitHub repository. Got it running in Debian (Proxmox), Gentoo and even Arch Linux. The cards are traded on eBay for >500EUR even with high usage. Due to its very low usage, I'm asking for 399...
Hi everyone!
I have an NFS share, where I'm planning to store my backups. I created a raidz2 zpool on 7 sparse files on that NFS share and transferred snapshots using syncoid to that zpool.
It seems to me that it's a working solution, but I haven't done that before and wanted to hear your...
I have a system that's on a supermicro with several jbods. It was all 4TB SAS, but put in 8TB SATA. It has had more drives fault in 6 months than in my 20 years in storage. I am an enterprise storage guy, NetApp etc. This was dropped in my lap and I can't figure out why this is happening. Any...
Hi, I’ve been using snap for at least over a year now without any problems and it was great.
Recently I decided to reinstall my system to ubuntu 20.04 but with ZFS as a file system. Since then I have weird problems with snap. After a restart I cannot launch any of my applications installed via...
Hi,
I've setup a Proxmox-Hypervisor and got a total write amplification of around 18 from VM to NAND flash. Can someone hint me how to improve this?
Server setup:

root drives:
2x Intel S3700 100GB (sda/sdb, LBA=4k) mirrored with mdraid...
I have a ZoL system (0.7.9-1) with 3 pools:
VMdata: Main pool with zvols for VMs (proxmox), daily snapshots running here
Backup: Backup pool where snapshots get replicated (Sanoid)
Pool3: Other empty pool
There are a couple of zvol that I want to access in the entirety from a few days back...
I installed Beta 2 on one of my servers, it has dual E5-2620 v3 CPUs, and 128GiB of RAM. I have 8x 4TB rust disks in a pool, and two 2TB SSDs in a pool. I have identical speeds and performance as I did with ZOL on Debian Buster. My previous experience with TrueNAS Beta 1 was not so hot, I...
The Oracle Docs illustrate mounting a zfs dataset under /export/dataset.... I might be missing something, but, why mount it? If you're doing an NFS export, why not just export /pool/dataset?
