segator

interesting not on mine (those disks are a zfs pool) shall I need to do something else?

question, how do you guys monitor the disk smart when using ZFS? unassgined devices plugin is not monitoring disks that are not mounted right?

Memory issue fixed increasing blocksize in the dataset to 1M ashift=12 disabled dedup and compression on not needed volumes (like multimedia vols) -15GB of usage. @Marshalleq which error you have, running latest beta with gaming VM and ZFS RC2 (NAS + DEsktop PC all in one) all working fine after my fixes with the memory. in your logs I saw you have disabled the xattr?

oh thats good point, I have also a dataset with some media files, i supose i will need to create a new one with dedup disabled and move data there, right?

yes I remember readed about 1gb per TB of data in my case I have 10.4T of data thats then 10.4GB of ram so If I sum my VM ram + arc + dedup 24 12 11 means out of ram tootally.. nevertheless I reduced now to 20 8 11 and i'm still on 0gb of free ram

in my case have a lot of benefits because the type of data I store on my volume. I build code and archive all the builds so the deduplication ratio is so high as the diference between build are a couple of kb. Anyway as far as I understood, teorically when linux need memory, ZFS free some memory of the arc cache, but its seems its not doing this, could be? also, do you know how this parameters affect when using ZFS on unraid? reccommended values in tip & tweak unraid plugin are: vm.dirty_background_ratio = 2 % vm.dirty_ratio = 3 %

how is this possible? i have 24gb for the VM 10GB for ARC cache and running nextcloud with redis and mysql and some rubish dockers. how can I see the real ram usage of ZFS? (arc + metadata cache + dedup.. ) I have 10.4TB on my zfs vol btw

Hey using from a couple of weeks ZFS on unraid with gaming VM as primary desktop pc (nas + desktop pc all in one), it works fine but sometimes unraid decides to kill my VM because "out of memory" i assigned 16gb of ram to the VM and the host have 64gb of ram, I think zfs is not cleaning enough fast the arc memory when other containers reclaim memory and then kernel decides to kill my VM i can fix it using hugepages but i don't like it because then its memory that ZFS can not use it when the VM is shutted down (that at the end is the 90% of the time), I tried to limit ZFS arc with echo 12884901888 >> /sys/module/zfs/parameters/zfs_arc_max but same

Ops I forgot to mention this error d: do_drive_cmd: disk7: ATA_OP e0 ioctl error: -5 appears always that unraid trying to stop the SAS disks, thats why i'm saying it's not working as it stays on loop forever until log is full in a couple of weeks

I don't know if maybe this could be your error: RTX 2XXX also have a usb device, maybe is the same with RTX 3XXX if this is the case ensure to add it, also remember to use the "multifunction" there is a video from spaceinvader one that explains how to passthrough correctly RTX 2xxx.

playing with ZFS RC2 seems working fine, how can i configure persistent L2ARC?

I'm trying to find out documentation about unraid plugin creation, but i can not find too many things. I have clear idea how to create the page and package the plugin but for exemple if I want to deploy a service that boot just after array start?

this defintelly will need a plugin.. it will be so nice a plugin with a UI with all the snapshots stuff and cronjob configurable. also this plugin could enable shadow copy smb feature

I modified the script for my needs, set VM nice at -20, nvidia-persistance mode on stop. it will be nice if we have something like this https://passthroughpo.st/simple-per-vm-libvirt-hooks-with-the-vfio-tools-hook-helper/ to unraid so we don't need to modify limetech scripts...

Hey @bonienl you are completly right but first I want to ensure what I wants works then I will try to help admin's to add those modules. What I'm trying to achieve is install kubernetes on unraid, but I have some problems with ipset and some networking modules.

Hello guys someone can give me instructions to build the kernel and package for unraid 6.8? I need to add some modules to kernel Thanks!

It works awesome!!! on my asrock ep2c602, but it seems the fan control don't see one of the FAN's CPU_FAN1_2, but it's weird because in the sensors page I see it and his values.

Well I checked while cache dirs is running and I have 3,5GB free acording to free -m command information If you're using windows explorer to check, be aware that it will inspect the files which is not part of what is cached, just the directory entries. You need to use a file client that wont inspect the files themselves. The best way to check if a disk directory is part of the cache is using a linux command shell and typing "ls /mnt/user/share/dir/subdir" or "ls /mnt/disk#/share/dir/subdir". If the disk is spundown and cached by cachedirs it should not spin up using that command. You're right, I have a binded smb directory to my windows computer, it's seems it's the problem. When i Start my computer the NAS drives automatically spin up. Using NFS it work fine, it's possible to use my cache drive as a read cache? something like NFS cachefsd that works very well I have read cached 1TB of my most viewed media in one server with plex installed.

Hi guys, I have this plugin installed but it seems that not work so good for me. I hear the drive every few seconds working and if I have look and the drive is spin down every time that I acced to a smb directory the disks spin up this is the log Mar 28 11:19:12 segator cache_dirs: Starting cache_dirs: Mar 28 11:19:12 segator cache_dirs: Arguments=-u -m 2 -M 5 -d 999 -i aina -i aportes -i encodings -i home\ video -i movies -i music -i photos -i segator -i software -i stcugat -i steamLibrary -i temporal -$ Mar 28 11:19:12 segator cache_dirs: Cache Pressure=10 Mar 28 11:19:12 segator cache_dirs: Max Scan Secs=5, Min Scan Secs=2 Mar 28 11:19:12 segator cache_dirs: Scan Type=adaptive Mar 28 11:19:12 segator cache_dirs: Max Scan Depth=999 Mar 28 11:19:12 segator cache_dirs: Use Command='find -noleaf' Mar 28 11:19:12 segator cache_dirs: Version=2.1.1 Mar 28 11:19:12 segator cache_dirs: ---------- Caching Directories --------------- Mar 28 11:19:12 segator cache_dirs: aina Mar 28 11:19:12 segator cache_dirs: aportes Mar 28 11:19:12 segator cache_dirs: encodings Mar 28 11:19:12 segator cache_dirs: home video Mar 28 11:19:12 segator cache_dirs: movies Mar 28 11:19:12 segator cache_dirs: music Mar 28 11:19:12 segator cache_dirs: photos Mar 28 11:19:12 segator cache_dirs: segator Mar 28 11:19:12 segator cache_dirs: software Mar 28 11:19:12 segator cache_dirs: stcugat Mar 28 11:19:12 segator cache_dirs: steamLibrary Mar 28 11:19:12 segator cache_dirs: temporal Mar 28 11:19:12 segator cache_dirs: tvshow
