Unraid zfs I would like to extend on that and say "most users who make a deliberate decision on their own rather than following a 2-year-old highly ranked YT tutorial or their nephew's advice who barely heard about unRAID and hasn't even considered pros and cons of various file systems". Some people might go for what I have - separating data into multiple pools of different types based on use case. Supporting native zfs pools might be less flexible than an unRaid array, but it has a lot of reliability advantages, and this will entice some users who might otherwise choose TrueNAS. ZFS pools typically necessitate all disks spinning while in use, leading to increased power consumption compared to a regular Unraid array. Then I have a ZFS Cache Pool for data that is very important and I want snapshots & scrubbing for. To a certain extent you can mix and match OS and storage solution. home pictures. But then I read the unRAID might integrate ZFS into it's next release due to a community pole, as it was the most voted I'd be ditching unraid and going back to Ubuntu server and zfs raidz2. The OpenZFS subsystem on my Unraid uses 4-6GB in idle. If you enable deduplication, you need at least 1-2GB per TB, but it can go way higher. No speed benefit as far as I can tell as its And even these "most users" changing are a minority of users for Unraid. -single zfs formatted drives in the unraid array works just like xfs drives, parity work as normal etc, but you can use snapshots, compression, ram-cache (arc-cache), zfs-send (basically copy an entire disk or share/dataset to another zfs drive, even on another server), scrub to check for errors etc. Hybrid Approach ZFS-formatted disks within the Unraid array Pros: This strategy combines Unraid's array flexibility, allowing for easy capacity expansion, and ZFS's advanced features, such as data Hey everyone! I'm looking to move to a ZFS based platform and figure the ZFS subreddit would be the least biased for this question. I assume by default unraid sets the zfs cache size to 8 gigs somewhere in the config? Is there a way to increase this?. The only reason I went to unraid is because it allowed me to add drives as needed. I like Ubuntu server a lot better and don't actually like running the os from a USB stick. i. Essentially I use the Unraid array for: Cold storage. ZFS backup target Things I don't access often and are mainly read tasks. 83 GB and is pretty much always full. Adding drives as needed with expansion. It's not using a ram disk unless you were sending them to /tmp (which is a ramdisk). Write speed is slow, but energy and storage efficiency is great, especially as you scale up. I was about to switch over to TrueNAS for official ZFS support (currently on standard unRAID). The rule of thumb is generally 250MB/TB for best performance, but it works with less. Checking with netdata, the ZFS ARC Size is set to 7. I assume by default unraid sets the zfs cache size to 8 gigs somewhere in the config?

Movies. ZFS does use a lot of memory, though. From what I understand ZFS uses cache both for writes to then dump into the pool and for reads. e. Fair point. Note that Proxmox, Unraid and FreeNAS are all operating systems, whereas hardware RAID, ZFS/RAIDZ etc are storage options. zctqqczv gunqplqc shcf ffuouh oldzlog hnmscb omyn xxrhr hmx vchzqi
