  • Oct 20, 2020 · As far as resource usage, unraid is quite a bit easier on system ram, due to not having ZFS. (It LOVES ram…) For storage, I allocated my 500gb NVMe to cache, 2x 2tb disks to the array, and another 2tb disk to parity.
  • So a little Goolge ZFS keyword searching later, I came across Joe Little's blog post, ZFS Log Devices: A Review of the DDRdrive X1. This got me thinking about my zpool setup. Looking at the configuration again, I realized that I'd made a mistake and added the second Intel X25M SSD to the cache pool instead of the log pool.

  • cache=none seems to be the best performance and is the default since Proxmox 2.X. host don't do cache. guest disk cache is writeback Warn : like writeback, you can loose datas in case of a powerfailure you need to use barrier option in your linux guest fstab if kernel < 2.6.37 to avoid fs corruption in case of powerfailure.
  • Mar 03, 2018 · I recently had the need to build a 2U Server for home and LAN party usage.

  • Jun 08, 2018 · On the Proxmox website, they say: “Proxmox VE is a complete open-source platform for enterprise virtualization.” And typically you can’t charge for open source software; but the folks at Proxmox have done their best to scare most of us into buying a subscription — or, at least, to make us feel guilty for not having one.
  • What happened was very interesting. The Proxmox VE rpool had failed. This was a mirrored ZFS pool using two Intel DC S3610 480GB SSDs. Not only did the drive fail, but it seems to have caused issues with the other SATA SSD ZFS pools on the machine, but not the VMs hosted on the NVMe SSDs. Yes, this was a fascinating one.
  • It had ZFS as an option, and I think it was the default. It was horribly slow. ZFS as a filesystem is just about the slowest on the market. Not designed for that at all. If you add SSD caching or whatever to it it does a lot, but it is all the LVM layer that is fast, the filesystem is super slow. Phoronix measured it at about half the speed of XFS.

Ubuntu server, and Linux servers in general compete with other Unixes and Microsoft Windows. ZFS is a killer-app for Solaris, as it allows straightforward administration of a pool of disks, while giving intelligent performance and data integrity. ZFS does away with partitioning, EVMS, LVM, MD, etc.
Proxmox, a webserver and a gaming VM are on a 2*2*3TB ZFS RAIDZ2. On a 256 NVMe SSD there are 4 Linux VMs. I haven't configured anything else. The arc cache size is only 8 GB and the whole server has 48 GB Memory. Now I enabled write-back cache on the Gaming VM and noticed Proxmox started swapping which is incredible slow.

  • ZFS (old:Zettabyte file system) combines a file system with a volume manager.It began as part of the Sun Microsystems Solaris operating system in 2001. Large parts of Solaris – including ZFS – were published under an open source license as OpenSolaris for around 5 years from 2005, before being placed under a closed source license when Oracle Corporation acquired Sun in 2009/2010. Nov 29, 2020 · Read the last command of this guide before continuing. Note2: If you are using your proxmox host for GPU passthrough it is adviced to set options zfs l2arc_mfuonly = 1 to not fill the cache with all sorts of crap if you are doing backups. It will most likely trash your SSD unless it is enterprise grade SLC within a few weeks.

Aug 31, 2019 · SSD Cache. ZFS has native SSD caching (L2ARC) support, and even a single drive you can use for read/write caching. The cache warms up quickly enough, but the peak performance of the SSD does not reach, so high-intensity operations are performed with data on SSD arrays. For SSD cache, you can use any number of pooled drives. Gilbert [email protected] Blogger 16 1 25, ...

  • One way to expand the capacity of a zpool is to replace each disk with a larger disk; once the last disk is replaced the pool can be expanded (or will auto-expand, depending on your pool settings). To do this we do the following: zpool replace [poolname] [old drive] [new drive] e.g.: … Continue reading "ZFS: Replacing a drive with a larger drive within a vdev"
