I’m away from my unRaid system until tomorrow evening, so this is just a suggestion until I can double check it ... log into unraid2 system. change directory to your TV share, eg cd /mnt/user/TV run the following command to produce a list of files into the file list2 find . -type f -print >list2 log into unraid1 system and do the same commands but put the output into the file list1 cd /mnt/user/TV find . -type f -print > list1 you will need to somehow copy the file list2 from the unraid2 system onto unraid1 and put it in the same directory as the list1 file then run the command comm -2 -3 list1 list2 >list the file list should now contain those files that are on your unraid1 system but not on your unraid2 system. Hopefully you can do something useful with this list.

Just to clarify .... when you say you can run anything on both machines, do you mean you have remote access to the 2nd machine or you can run something when at the location of the 2nd machine?

My suspicion is that you might have some device on your local network which is using the same IP address as your unRaid system.

Yes. I am running exactly that setup and it works just great for me.

What is the processing power of your Unraid box compared to your windows 10 box? I assume that whatever software that is sending it to the cloud server is doing it securely and encrypting it which might account for the different speeds if there is a significant difference in processing power and/or efficiency of the encryption software on the 2 systems.

Yes. When you are remote and enable a connection to your OpenVPN server, all your device’s network traffic will be directed via the OpenVPN server and the device will be allocated an IP address on your home network. Therefore your device will behave as if was connected directly to your home network with its own IP address.

No. You set OpenVPN up on one server. When you connect remotely via OpenVPN, your remote device will appear as if it is directly connected to your home network. So any system you can access when using your device while at home, you will also be able to access via the remote connection.

Security! if you have opened ports on your router to access applications on your systems then each one is a possible avenue for someone on the internet to exploit if any of those applications is not securely configure or has bugs which can be exploited. Some of those apps might not have been written by security experts as that is likely to be its secondary purpose. Also all the network traffic between you and your home system can be potentially intercepted and analysed and used to attack your home system. How secure is the Wi-Fi connection you use at the hotel/bar/etc that you might use? Do you know who controls all the network devices that handle the network traffic between where you are and your home system and do you trust them? By using OpenVPN you are ensuring the connection between you and your home network is protected by having all the network traffic encrypted and you are using an application specifically designed to be secure and only requires a single port to be opened one your router. This all significantly reduces the likelihood of a security breach into your home network.

I have to question your very first statement that you replaced a faulty disk, In what way was the disk faulty which made you replace it? Was the disk completely dead and not seen by the system after a system boot? Was the disk showing SMART errors? Were you getting sector read/write errors reported in the syslog? Most disk problems are due to issues with the cabling, controllers, power supply with actual disk failures probably the least likely problem. Then there is the problem that there is no actual problem with the hardware but for some reason the file system on the disk has some corruption (this sort of thing can occur after something like an unclean shutdown) and just needs the file system check/recovery to be run. Replacing a disk and rebuilding it will not fix this problem, it will just exactly replicate the corrupted file system on the new disk. The format option is given as a option if the system is unable to mount the drive, which can be due to there being no file system that Unraid considers valid (which includes a corrupt file system). As you have been offered this option I suspect there was nothing wrong with your original disk but the file system had some corruption on it. My advice at this stage is to let the rebuild complete and then seek advice here on how to fix file system corruption. Keep the ‘failed’ disk in case it is needed to help recover file. What ever you do, do not do any further actions without advice .... otherwise you are likely to do something which will prevent recovery of the disk . And certainly do not select the format option.

You should include backslashes so it is of the form ... \\ip-address\

I must admit, with the growing size of disks the parity check is becoming an issue. On my system, which has a mixture of 4tb, 6tb and 8tb disks the parity check is taking around 27 hours. When I buy another disk I would like to go to 12tb disks .... but a possibility of a 50% increase in parity check time is a bit worrying. There has previously been a suggestion of allowing parity checks to be split into multiple runs so that it could be completed over a number shorter runs on different days. With the ever increasing size of disks this is becoming more and more of an issue.

Hmmmm. Without a monitor attached to the unRaid system I’m not sure how you see the progress/results of running memtest from the boot menu. Maybe someone else has had experience of running memtest headless can tell us.

Not sure .... assuming you only have one license, go to existing unRaid server Tools -> About -> Registration and see what date it says that license was registered. i am assuming that shows when that license was registered with that USB device rather than when it was first purchased.

Buy new cruzer fit USB drive. On existing unRaid server Main -> Boot Device -> Flash -> Flash backup Run USB creator on new cruzer fit USB drive to create new unRaid boot disk Re-Run USB creator telling it to restore the Flash backup you made earlier. Boot unRaid server with new cruzer fit USB drive. unRaid should recognize that the license key does not match this USB drive and offer to transfer it to this drive. Note you can only automatically transfer a key once a year to a new USB drive (otherwise you have to contact LimeTech support for help) ... and the old drive will be added to the unRaid blacklist. So the question is, how long ago did you move the license key from the cruzer fit USB drive that you are having problem with? If it is less than a year then you will not be able to automatically transfer the license to the new USB drive and will have to contact support instead for help getting a new license key for the new USB drive for the last step.

Have you previously had Unraid installed on that cruzer fit drive and you transferred the license to another usb drive? If so that would have added the cruzer fit drive to the blacklisted drives in Unraid and is no longer suitable for use with Unraid. You will have to use a different usb drive.

Not that I think it could be the cause (because it would usually result in corrupt file systems and other problems), but have you run the memtest from the boot menu to check you haven’t got some bad memory (I didn’t see any mention of it when I skimmed over this thread) that only gets used as a buffer when large files are being copied? have you tested if the files get corrupted if the system is in left in safe mode when there are new files, with ALL plugins, dockers and VMs turned off (this would then give you a baseline from which to continue investigation)? Leaving some running just because you think they could not be the cause is not a good idea in this sort of trouble shooting.

In order to rule out whether mover is the problem, temporarily change its schedule so that it won’t run in the next 24 hours (this assumes you have enough space on the cache disk to do this). Then see if the files are getting corrupted .... if they are still getting corrupted then it would rule out mover as the cause. Then manually run mover and check again. Finally put mover back on its usual schedule.

Would it be worth adding a sticky with guidelines on raising issues on this new support board, such as proving release on which issue occurs in, full description, how to reproduce the problem, any error in logs and/or diagnostics file, etc. One of the first issues raised was basically just a "problem still occurs" report which after a few days, certainly after a release or 2 is practically useless.

In Linux the permissions to delete a file depends on the write permission of the folder that contains the file and execute permissions on all parent folders not the file permissions/owner.

Have you tried some of the other Unraid boot options? In the past occasionally people who were unable to boot the non-gui Unraid could successfully boot the gui version (and visa versa).

My initial thoughts if this is a very old system is that the battery on the motherboard that keeps the bios settings alive needs replacing and therefore you need to check the boot device set in the bios , because if this is the problem it has probably changed to look for a hard disk rather than a usb drive.

You can use either command .... my personal recommendation is just use which ever command you are less likely to make a mistake using and accidentally lose files. As you have a /mnt/user0 then you must also have a cache disk set up ... so you should also read up on how a cache disk works when included in a share.

Suggest you look at the Unbalence plugin which does exactly the sort of thing you want.

The limits for the v4 and v5 licenses are detailed here ... http://lime-technology.com/wiki/FAQ_for_unRAID_v4_and_v5#How_is_unRAID_licensed.3F

As the backtrack shows the crash is occurring in the XFS driver, the 1st thing I would do is run a file system check on your disks .... you might have some file system corruption which is causing the driver to crash when that part of the file system is accessed.
