I set this up as a test as was getting a weird issue where the VPN would block access to file shares, I had mounted on the Win 10 VM. Had this setup exactly as I needed it and change the drive letter by adding some items to the registry. All looked fine with access to the drive added yet when I had more activity against the share, I was getting multiple IO errors. Has anyone had a similar issue or is access to the shared drive OK for those that have set this up. I stopped the windows service in the end and reverted the VM config so not using it now. With a plan to look it later as this is still a new addition, and a few bugs is to be expected.

This should open up the ability to have a hot spare drive. Could be something simple like the hot spare has to be the same size as the parity drive. As the parity drive has to be the same size or greater than any other drive. If your parity drive fails the hot spare becomes parity and automatically rebuilds the parity If a data drive fails the hot spare replaces the data drive and data is rebuilt on it You could then have the option of allocating 1 or a couple of slots as hot spare drives to increase the resilience of the array. Maybe even have a tick box option to set what the hot spare can be used for, parity, data or both.

I did not have notifications enabled but I do now, thank you for mentioning it

A very valid comment and makes me need to think twice about my approach. I have 2TB drives that I purchased several years before the 6TB ones. All the 2TB drives are still working fine and the newer (out of warranty) 6TB ones 3 have failed, leaving me with 4 left. From a reliability standpoint I probably have more faith in the 2TB drives then the 6TB ones. I keep an eye on the SMART status of the drives and if any show signs of failure they would be removed after the data moved to other drives.

I do not have the issue but trying to get my head around the scenario as no doubt it will happen as I have 3 dead drives sat on the side already. Setting up new unRAID (I am still new to it). This is a replacement of my old setup and the disks are moving from old to new so not all new disks. Parity is a new WD Red 20TB remaining disks are older WD Red 2TB and 6TB. My plan is to stick them all in the array and as one dies then get rid to the point I need new disks. Looking at recovery options my plan seems flawed as all the ones I have seen require a replacement disk of same or greater size to be able to rebuild data from parity. Or you move the data off the disk then remove the disk from the system prior to disk failure. Is there a way, in the event of a failed disk to rebuild the lost data to another drive already in the array. Or would I essentially need to keep a spare larger drive. Use that for rebuild, move the data off it after rebuild then remove it from the array to be a spare again. On that, are there any plans to add the ability for a hot spare in unRAID so that in the event of a disk failure the automatic replace \ rebuild can start.

I would hate to see your electric bill Just 1 for me, well 1 at trial stage while I test things to see if I take the plunge.

If I decide to restart I will try it, as at the moment it is either get Unraid working or back to Windows Server as the host and managing the disks with Hyper-V for VM's.

I have followed this thread and other similar one’s in the hope they will lead to resolution of the same \ similar issue I have. Unfortunately, that is proving to not be the case, here is my issue to add. If anyone can at all see what I am doing wrong please say as my sanity is slowly leaving the building. I have Unraid Trial version running. I want to see if it is right for what I need…. Unraid has 20 shares setup and AD joined. AD server is a VM on another physical server so not a VM on Unraid. I have 1 Windows 10 VM on Unraid others a physical Windows 10 devices. My issue is, it really seems to depend on the wind direction if I can access AD managed shares on Unraid and also which account can access them. I have the added elements discussed here added to smb config. My config matches the recommended settings discussed in this thread. I can add all those details if anyone wants to check. I can check (getfacl) and shows users have access but when they try to access, they get access denied unless I set permissions to everyone full control. Which sort of negates all the aspects of file level security. I can query the SID for accounts fine but still get the smb access errors on some account on certain shares. Done a reset of all permissions several times and seem to be in a loop of needing to redo that for it all to stop working and start again. Some times I can access shares on Unraid, other times I cannot and have no access to any shares on Unraid for any account. Several restarts and join \ leave AD (leave takes multiple attempts to leave) seems to fix that for a period of time, it really is all hit or miss. I have considered starting from scratch but to rebuild and data transfers is looking like a week activity. Unraid brings with it some major positives I want for the disk side of things where I can use different sized disks. The file access from AD is making this a no-go area as it is all well and good having flexible storage but no use if you cannot manage those shares when you have AD deployed and this is supposed to work with AD. You can get away with this on a free product but not something you have to pay to use. What does concern me is a distinct lack of engagement from Unraid Devs on what is an issue impacting multiple paying customers of their product. I guess the only positive is there is a very helpful community trying to solve this but the lack of product owner input is bad.

Currently running trial version as I get this sorted in my head to see if I finally move to UNRAID. Old Setup, Windows Server running Windows 2019 DC. A few VM's (Windows and Linux) plus some Appliances (PFSense and Home Assistant) all running in Hyper-V. All disks assigned to host 2019 server and shared out from there. Either as shares on the Host or added to VM's. AD ruinning too on host and a VM. Lookign to move to UNRAID to replace the old server (it is very old). The problem I have is the AD servers will be a VM on Unraid. As will any other device as a VM. How does UNRAID function on startup as a domain join for the issue of file shares when it needs to start the array and the VM's for AD to be available. Hence the chicked and egg. Also what is the best way to have shares presented from UNRAID to a Windows VM to then be shared out and managed from AD. Has anyone done a similar setup to say if this is even workable or do I need to rethink my approach here. Which could be to present storage to the VM's then share that out and not do shares from UNRAID. Which is actually starting to seem like the most logical approach here. Edit: Done some playing around and looks like only way to get what I am after with AD managed shares with the AD Server as a VM on UNRAID. Is by adding additional virtual disks to the VM which it then has the shares in there to share out under AD control. If anyone has a better workable solution please feel free to advise.

Thanks for reply, it was more in the aspect of the VM licencing not unraid licence. Where people are running multiuple windows VM's what licencing options are there for the VM. Is it a windows licence per windows VM or if you have a data centre instance of Windows. Would that cover multiple windows VM's on unraid as it does unlimited windows VM's if it is the host.

Hi... Totally new to unraid but have looked at it on and off for a while. Came to crunch time when my aging home server started to have disks die. It is very old... That started as a 2008 Server (when 2008 was new lol) and progressed over time to 2019 DC running hyper-V with 8 x 2TB WD Reds and 7x 6TB WD Reds in 2 arrays off seperate RAID cards. Now the 6TB's I have had a couple die and I replaced with WD Red Pro 20TB with the plan to slowly redo the array to 20TB drives. Simple aspect those drive when the stars align and the wind is right are £399. Rest of time they can be around £600. Which is way more than I want to pay So now I started to look again at unraid as the ability to support mixed drive sizes is a very attractive option. Hardware I plan to get \ got for this. ASRock Rack X570D4U Radeon R75700G 2 x 32Gb Crucial RAM (not ECC) as per supported list for Motheboard AIO fro CPU Not decided yet on SAS HBA but could be a LSI 9207 SAS 8i HBA if I can find out what size drives it will work with as I have 20tb ones Fractal Labs Node 804 for it all to sit in. After the waffle my main query is... I know it is better to use ECC RAM, the mother board supports it but the RAM cost was nearly double and the the CPU was over £120 more to also support ECC. So non ECC was they way I decided to go. As I currently have win 2019 DC that covers me for unlimited windows VM licences. Does anyone know or have have links to what a server licence model would be on unraid. As nothing I have found is clear. I know the host Windows Server can have 2 VM's as standard and unlimited if DC. Just nothing on if it is not the host. I am assuming each VM now needs its own licence. I have a few Windows VM's but also Linux and other things like Home Assistant and PFsense. It is mostly used as a file and media server. I am looking to move all those across and also looking for mail server for home use I have an ancient version of Exchange running and want to get away from that and more to open source stuff, so any suggestions welcome there. Anyhow waffled enough all (nice ) comment welcome.
