    Do you know perhaps what practical implications disabling IOMMU has?

    Or is it perhaps a bad thing to have it enabled since new kernel/unraid doesn't work with it?

    I read a bit on wiki, but... it is out of my scope of knowledge(/interrest).

    Disabling IOMMU means that you cannot run VMs with hardware pass-through.   You can still run VMs that do not need hardware pass-through.   Marvel controllers also seem to be prone to dropping disks offline for no discernible reason. 

     

    The issue seems to be a compatibility issue between the Marvel drivers and the latest Linux kernels.  The fix (if one is possible) is outside Limetech's control.   If you want to run VM's with hardware pass-through then the easiest thing to do is to stop using the Marvel controller and switch to using a LSI based one which work fine with current Linux kernels.

  2. I believe this is probably an instance of a long standing issue where once you have made any edits in XML mode then you can no longer edit that VM in form mode without potentially losing the edits made in XML mode.   I have wondered why a pop-up warning to this effect is not displayed when you try to switch back to form mode from xml mode.

     

    This is slightly aggravated by the fact that the toggle for xml mode is a global one and not specific to a VM.   If the underlying problem cannot be easily fixed then it would be useful if the system remembered the last edit mode used for a specific VM so that at least if you go into Edit mode then if you used XML mode you are taken straight there.

    hi can someone please help me, i have a lot of folders on my /mnt/user0 , where should i move this folders to be safe for the future, thanks

    Not quite sure what you mean by this?    The /mnt/user0 location is just a view that is a sub-set of /mnt/user that omits any files/folders that are on the cache.   As such you have no files in that location that need moving.

    Yes, though my scripting skills aren't great but the ability to shutdown dockers and plugins before a parity check would be handy.  Though I'm assuming doing so would speed up the parity check.

    I suspect for most people this is not a major criteria as performance heavy options are probably mainly running from the cache drive which is not affected by the parity check.   There is also the fact that using the plugin to only have parity checks running increments outside prime time the parity check speed may be less critical.

    I'll have a look at the plugin as if it allows me to stop selected services and docker containers when doing the parity check it might be handy.

    I am afraid stopping/starting services is not part of the plugin as its primary purpose was just to avoid parity checks hitting system performance during prime time.   It seemed a step too far at the moment and rather difficult to implement in a generalized fashion.

     

    What I have been thinking of adding is an ability to run custom scripts on parity check start/resume and pause/end.  If I get this in place so you can do your own stop/starts is this likely to be of use?

  6. This has been the case ever since the pause feature was introduced.  
     

    Not a fix, but if you have the Parity Check Tuning plugin installed it ‘patches’ the history entry to give the correct details for the whole of the run (as well as providing some other features you may find useful).   Having said that I perhaps need to check that this is always the case when manual pause/resumes have been done rather than automated ones.  I think it is handled properly but I am not 100% sure.

    I initially had my diagnostics folder uploaded, but it was pointed out to me there was some personal information I'm not comfortable posting publicly. I will happily provide the zip to the appropriate staff!

    It would be interesting to know what type of information this was as the Diagnostics are meant to be anonymised to avoid exactly this issue.   Maybe there is some further tweak needed.

    When I attempt to run that cmd (with the array stopped), I receive an error message: 

    /usr/local/sbin/mdcmd: line 11: echo: write error: Invalid argument

    Are you on rc4 when you try this?   I have a feeling that is a new option in rc4.

    Does RC3 have kernel above 4.2? I want to use my 9th gen intel integrated graphics for transcoding.

    You should check the release notes for a release to determine the kernel used.   Most new releases of Unraid will have an updated kernel so that is a moving target as releases progress.

  10. What subnet is your phone on when this happens, and what are the subnets for for the Unraid server and the dockers?  

     

    I think I saw a report of similar symptoms when the remote subnet and the subnet used by Unraid were the same as this resulted in a routing issue.  If this is the case then it is going to need looking into for the most robust solution as the user rarely has any control over the remote subnet.

     

    If course it could be my memory is faulty and your issue is something completely different :)

    Just out of curiosity though, what would would happen if you remounted the flash, and when does the mount happen in relation to the go file?

    If you think about it the mount must happen before the 'go' file executes as otherwise the 'go' file would not be found in the first place :)   In fact the mount must happen very early in the boot sequence as the flash needs to be mounted to enable Unraid to read all its configuration information.

    Just curious, if the mount time is after the go file, can you remount with different permissions? or if mount time is before go file can you remount with user scripts with different permissions? thanks

    Why bother?   You can always use the 'go' file to copy the scripts to a location from which they CAN be executed.

  13. I am guessing that this problem is caused by the following change from the 

    release notes (which was made to increase security):

    Encryption - an entered passphrase is not saved to any file.  Also included an API for Unassigned devices plugin to open encrypted volumes.

    This probably means that Unassigned Devices can no longer find the pass phrase and is going to need some rework before in can support encrypted disks again using the API mentioned
