I am looking for a solution I can have the benefits of unraid + snapshots - JBOD - Parity Drive - Only spin up disks where files been used are located - See all drives as a single volume - If 1 or more disk fail only lose data of these disks. - SSD Cache Write Disk -Also would be interesting have SSD Cache Read Disk (avoid spin up drives on more readed data) - Snapshots For the moment I only be able to have all this features using glusterFS + LVM, but I would like to have the simplicity of unraid OS(Pendrive OS based), UI and notifications of disk failures and SMART

OS: Unraid 6.2 Pro CPU: Dual Xeon E5-2670 - SR0KX stepping Motherboard: Asrock EP2C602 RAM: 32GB ECC buffered 1333 mhz quad rank Case: nanoxia deep silence 5 Drive Capacity: 16x3.5 (5 hot plug 11 intern) (Motherboard only have 14 sata, I will need a HBA in the future), 1 have 5.25 bay empty so I can add a enclosure 6x2.5 if i want Power Supply: EVGA SuperNova 850G2 Fans: 1 Rear, 2 cpu fan, 3 HDD fan Parity Drive: 8TB Seagate Archive Data Drives: 8TB seagate archive 2x2TB Seagate 4TB WD red 6TB WD Red 2x3TB WD Green Cache Drive: 1TB Seagate (normal drive) Array Capacity: 28TB Services: Plex,Deluge,TVHeadend,Jenkins(automated video encoding to microHD after download),Rancher(Docker host clustering UI),(Test Purpose)Windows 2012 Server, Centos, RancherOS, Windows 7(Rendering machine),crashplan,duplicati Used for media center and cloud storage server and lab-server, I usually work with simulating clusters to test different cases so I need to create multiple VM. And My GF need a lot of power to do 3d render. I know the case it's not the best but I can't handle waste 300$ for a case... and I had some problems find cheap cases with EEB form factor this case can handle with the 5x3 enclosure 16 HDD, for me it's enough. very very silent!!! it's difficult to know the server is turned on by ear. very good performance, first days I was trying to have 2 VM gaming and work perfect! no errors about power consumption I'm more or less over 100W in idle and 370W at full

Hi sorry it's 850W the psu about maybe i'm wrong but i thought your power supply is limited to the sai output, it isn't? my sig is fine is exactly the machine were i having this trouble. I though the problem was the power supply but I changed the sata cable of the 3 drive that I get disconnections and changed to an other sata controller, ran parity check and no errors and no disconnections. It's weird to think about this 3 cables have problems, and I have more HDD pluged to this "problematic sata controller" and are working fine. So i'm not sure what is the problem

as far as i know it's not possible you need to passthru whole usb controller or single divices, but I remember someone talking in other forum about some usb hub with integrated usb controller(maybe works)

I just have working DSM 6.0.2 on unraid, check xpenology forum. Mandatory set eth to e1000 and HDD to sata I pushing this guys to add the virtio drivers work pretty fine, but my first objective to install xpenology was to use the new feature of DSM6 "hyperbackup" but DSM doesn't like to create backups from NFS sources(yes i have my unraid shared folders mounted with NFS) maybe exist a way to cheat the OS to think it's hard drive directory not a mounted FS. Incremental/deduped + encryption + versioned backups on different cloud providers the major feature is that you can see a timeline in the file explorer with all the version of a single file/folder. so it's very interesting for me this feature. anyone know an webapp or something to do exactly the same?

Wow, when they are going to deliver? I'm thinking to buy 2(I'm from spain and amazon.de send to spain )

Hi 2 week's ago I changed my server to more powerfull server with dual xeon e5-2670. was working pretty fine but yesterday the parity check was activated(1 every month the first running on this server) And surprise I get on 3 drives multiple read/write errors, the powersupply have 700W but I have a sai with 480W, could be the problem? because doesn't have sense to have 3 drivers with errors. I restarted the server and now i'm getting a drive disabled, Maybe the sata cables, maybe the controller? I have the MB http://www.asrockrack.com/general/productdetail.asp?Model=EP2C602 what should I do, i don't think have any problem with the HDD, checking the S.M.A.R.T data all is fine. EDIT: I checked the HDD, all are fine, i suspect something releated with the PSU because the 3 HDD are connected to the same PSU electric cable(the typical cable with 3 sata connectors) For now I replaced the sata cables and conected this 3 HDD to different controller.(SAS controller)

Depends on what do you want exactly you should set one thing or other The problem is that xpenology don't have the kvm virtio drivers, for this reason you need to set as a sata/scsi or ide device(best sata, because have better performance than scsi or ide) If you want to create a virtual disk(single file inside your unraid system must be in the cache or outside the array!) you can set something like that <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='writeback'/> <source file='/mnt/disks/SSD/VM/Xpenology/vdisk1.img'/> <target dev='sda' bus='sata'/> <boot order='2'/> <address type='drive' controller='1' bus='0' target='0' unit='0'/> </disk> you also can passthru a disk to the VM or a LVM partition. What I did? create a virtual disk (file image) and inside the Xpenology use NFS to have access to unraid Shares) and yes you can use download station fiel station with your unraid shares but the performance it's not the best. anyway you need to create a vdisk to allow xpenology to have space to write the OS files and applications

hda is used by the ISO, why do you want to change the vdisk to hda?

Hi guys I supose that you like as me wants to have a very low powered NAS with lot of TB of media and have running a plex server. But the main problem is low power = slow transcoding. So I view a topic in the Plex forum talking about remote Transcoding, the guy who talk about it had a script in python to execute transcoding in remote machines. So awesome. the main problem is that you needed to setup it manually. I wanted to have it automatically using cloud computing. it's for this reason that I wanted to do a proof of concept and I create a plex docker with this automtic feature If you want to try it and give me some feedback or help me with the development. go ahead here is the sources and the docker and docker compose. The dockers are in docker hub ready to use. I couldn't do it work over unraid I needed to create a KVM with an ubuntu. The problem it's the NFS server docker it seems that not work over unraid I don't know why, i'm not an expert, if you can help me I appreciate it. here is the link with all.(This is my first project on github, tell me if I have something wrong) https://github.com/segator/PlexRemoteTranscoderDocker Thank guys

I have working pretty well xpenology KVM over unraid. The key to have KVM working is change the virtio harddrive to scsi o sata virtual model and virtio network to e1000. I don't know exactly but in a proxmox server it works with virtio network & scsi HDD but in unraid 6.1 need to be scsi/sata and e1000. About using your unraid shares in Xpenology for now the only way I find out is using NFS, it works pretty well, maybe it would be better use 9p kvm sharing but I cannot be able to do it work in Xpenology I suppose kernel need to be ready to that and seems it's not the case with xpenology. About your problem instalation that the system tell to you that no HDD is because you have the virtio driver, change it to scsi/sata and it works.(you need to modify the KVM xml file)

Hi guys, I'm thinking the posibility to join my personal game machine with my NAS. But i want to know if its possible to shutdown the GPU when the VM that have the GPU passthru is powered off. I don't want to have the gpu 24/7 if I only use my personal computer 2 o 3h x day. I have a gforce gtx 780ti the motherboard and cpu to be decided (I'm open to suggestions) I've thinking on i7 6700K and 32GB RAM and a 2x ibm m1015 to plug my 12 HDD drives

HI to everyone. I have Xpenology VM with NFS mount from unraid Host, work fine but the performance is poor I only get 30MB-60MB/s of upload-download. I wanted the hard drive unraid system + Xpenology web UI. for online it's work pretty fine but if I planing of use smb/NFS from xpenology in LAN performance it's poor. I have the network in e1000 because the virtio driver is not recognized by xpenology and the HDD is in SCSI driver because the virtio is not recognized too. Any of you have the same system as me? do you know how to improve the speed? Thank you guys.

Hi guys I was trying to make works cache_dirs plugins but when enabled always is scanning my disks with the find command so I disabled. I was playing with cache pressure 0 in one server (non unraid) an works perfect first time ls -l -R take it's time but second and thirst time it's almost instant. but when I set the sames values (cache presure 0 and swappiness) don't work always spin up disks and access to get the dir information with ls -l -R.. I want to avoid that applicaitons that scan directories spin up the drives. I have 4GB of ram and when I use the ls -l -R first time when finish I get 2GB free Ideas? thanks

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.

Well I checked while cache dirs is running and I have 3,5GB free acording to free -m command information

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

Hi guys, I a happy owner of unraid from 2 years ago. I played a lot with my server and install things that i shouldn't installed. this cause that now I see some errors related to plugins and VM-KVM web ui doesn't work i can't create VM. So I want to reinstall unraid but I don't want to lose data and shares. all the apps are dockerized so it's not a big deal to "reinstall the dockers" I don't care if I need to regenerate parity data, 1 month ago last parity check. Guys how I should do it? -I don't want lose data -I don't want lose shares -I don't want lose unraid Licence Thanks!

Hi to everyone, happy new year all of you!! I'm a happy owner of a unraid since 2013 But today i have seen syslog for maintanance and i get this errors I should worry about something?

I used VM creation web UI of unraid lot of times and always works fine, but yesterday I removed a VM and the add buton now dont work, i click it and nothing happens. i have seen the chrome console and appear this next error. implode(): Invalid arguments passed in /usr/local/emhttp/plugins/dynamix/include/DefaultPageLayout.php(276) I think the problem it should be something about failed deletion of the old VM, don't know but it doesn't work and now i need to create VM any help? thank guys!

are there any way to shutdown PCIE devices that have been passthru when the VM is not running? it could be interesting because the high power consumption that this type of system's do with 2 o 3 GPU.

it seems very well , but if you only have 1 usb controller and 1 SATA controller and you want to passthru some USB devices to one VM and other to other VM and passthru 1 SSD to one VM and other SSD to other VM, how you could do it? i remember 2 or 3 month ago I tested it system but i had lot of problems with usb.

did you try to access through ipmi whhen this error happens? do you have access? did you upgrade bios firmware and sata controller? it's very necesary because exist an error that makes unraid unestable.(HDD link lose) I have same MB with last unraid 6 version and all work very very fine.
