New – Amazon FSx for OpenZFS | Amazon Web Services

Last month, my colleague Bill Vass said that we are “slowly adding additional file systems” to Amazon FSx. I’d question Bill’s definition of slow, given that his team has launched Amazon FSx for Lustre, Amazon FSx for Windows File Server, and Amazon FSx for NetApp ONTAP in less than three years. Amazon FSx for OpenZFS […]

Got OpenZFS?

OpenZFS v2.0.0 targets Linux and FreeBSD – shame about the Oracle licensing worries

Various enhancements but merging still a big no-no

Got OpenZFS?

ZFS 租用服務

看到「zfs.rent」這個網站：

We have a couple of ZFS-based NAS systems. We wanted a simple cloud service so we could run: $ zfs send -v -R -I pool/snapshot_034 pool/snapshot_042 |\ ssh [email protected] zfs recv -v -Fu pool/snapshots

看起來是用 Linux 上的 OpenZFS 架的，每個 instance 提供 4GB RAM，這個部份應該還好，但只提供 1TB 的流量 (上傳與下載都要算)，這部份看起來就有點不太夠用了，以這種服務來說蠻容易踩到 overcharge 的部份。

作業系統的部份可以選擇 Ubuntu 20.04 或是 CentOS8.2。

OpenZFS benchmarking with 4 x NVMe drives.

System spec: - CentOS 8.2 - 2 x Xeon E5-2648L v2 - 384GB DDR3 1600Mhz - 4 x WD SN750 1TB NVMe drives

ARC capped at 64GB, working set size 72GB. Using fio from EPEL.

Pool configs:

/dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 raidz /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 raidz2 /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 raidz3 /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 mirror /dev/nvme0n1 /dev/nvme1n1 mirror /dev/nvme2n1 /dev/nvme3n1 mirror /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1

Script is gisted.

Capacity, performance, reliability. Pick two. 4 x NVMe drives, choose wisely. ⠀ ⠀ Pooled = No reliability.⠀ RAIDZ2 = No performance.⠀ 4-way mirror = No capacity.⠀ RAIDZ1 = The compromise.⠀ ⠀
