The system is running: SunOS Release 5. We have an older generation Sun T2000 system, with dual harddrives in a Sun ZFS mirror root setup. I'm looking for some input and opinions before proceeding with this though. Sun T2000 failing to boot with ZFS root filesystem. Or maybe just use one for the OS and the other one for L2ARC perhaps. I'm thinking I should perhaps replace the drives with a single, less expensive SSD and put the D3s to better use. It is licensed under the terms of the BSD License and runs on commodity x86-64 hardware. I disk failure is no catastrophe as it should be quite straightforward to set up the system again. TrueNAS is the branding for a range of free and open-source network-attached storage (NAS) operating systems produced by iXsystems, and based on FreeBSD and Linux, using the OpenZFS file system. Also I am not so sure about the benefits I get from the RAID / LVM setup. Due to most of my stuff running in Docker containers and those, as well as all my file storage, is located on other drives than my OS, I am using less than 10 GB of the drives. These are quite expensive drives for a simple server setup like this. However, I'm thinking that the OS drive setup I'm running on might be a bit overkill. I find myself having to set up the OS from scratch due to running on an EOL version and I need to upgrade to 22.04. I built it a couple of years ago and the HD configuration is something like in the diagram below. # zfs send -R zfs/logs/project-1 | zfs recv zfs/logs/project-3Įrror: Unsupported flag with filesystem or bookmark.I have a home file-/media server based around Docker applications and ZFS storage running on Ubuntu Server. YMMV, maybe I was just lucky for the last 25 years, but Im using it on every Mac and not having any problems. ZFS is a next generation filesystem that supports many advanced storage technologies such as volume management, snapshots, checksumming, compression and. This lecture was presented as Lecture 6 of Marshall Kirk McKusicks class, FreeBSD Kernel Internals: An Intensive Code Walkthrough, taught in the spring of 2. ARC: Adaptive Replacement Cache, the algorithm used by ZFS to cache data. Now I tried to copy it to another one (on local machine for tests, but I will be doing it over ssh later on) # zfs unmount zfs/logs/project-1 HFS is ancient, bloated and hacked to death, Linus Torvalds calls it the worst filesystem ever, and yet I still have to lose data due to a broken HFS filesystem. OpenZFS, arguably the heart of TrueNAS, is the open-source file system and. If you are creating a file system from a backup, you can specify a storage capacity equal to or greater than the original file system's storage capacity. Zfs/logs/project-1/branch-4 0B 673G 256M /zfs/logs/project-1/branch-4 FSx for OpenZFS file systems - The amount of storage capacity that you can configure is from 64 GiB up to 524,288 GiB (512 TiB). Zfs/logs/project-1/branch-2 96K 673G 96K /zfs/logs/project-1/branch-2 ZFS was designed in 2001 by Matthew Ahrens and Jeff Bonwick and it was supposed to be a next-generation file system for another Sun Microsystems system called. This creates following filesystem: # zfs list Zfs snapshot clone zfs/logs/project-1/branch-3 Here is my use case (I already have zfs/logs filesystem): zfs create zfs/logs/project-1ĭd if=/dev/urandom of=/zfs/logs/project-1/branch-1/test1.bin bs=16M count=16ĭd if=/dev/zero of=/zfs/logs/project-1/branch-1/test2.bin bs=16M count=16 "Generate a replication stream package, which will replicate the specified file system, and all descendent file systems, up to the named snapshot."īut instead I am getting error Error: Unsupported flag with filesystem or bookmark.
