I have two, possibly three outstanding problems with an Unraid server that I have built for a friend.

The hardware & software is nearly identical to my own Unraid at home which works perfectly.

 

I have not been able to obtain a resolution by myself (including posting questions here) and would like to pay someone to fix it properly.

 

Problems :

Error message : unable to write to disk5

Permissions errors of various sorts when trying to write files to the server

Problems reported by the user of problems trying to copy 1TB folders from iMac to server

 

In all cases we're using MacOS to access the server.

 

I can provide remote access by way of a screen share session from my iMac.

From there you can have browser or terminal access to the server.

 

I'm happy to agree a fee for one hour of investigation work to determine / fix the fault.

 

Diagnostics files are attached.

 

Thank you

Shane

There is file system corruption on disk5 so it is being mounted read-only to prevent any further damage to the file system.

 

You need to run a file system check/repair on that disk.

Thanks. I've booked a trouble shooting session with Limetech.

 

Can I run a file system check/repair on disk5 from within Unraid ?

 

It's currently running a parity check across the whole system.

FWIW, disk5 has no data on it.

I haven't looked at your diagnostics, but if there truly is no data that you want on disk5, then the easiest thing to do is stop the array,  click on disk5 in the main page, select a different file system type, doesn't matter which one, apply the setting and start the array. It should have a check box where you start the array saying disk5 is unmountable, do you want to format it. You check that box so it puts a new format on disk5. Stop the array after it's done formatting, change the file system BACK to the original, and start the array once again selecting format.

 

That should create a fresh file system that will accept new writes.

 

Don't do this if you don't understand what and why you are doing each step, you very well may lose data you weren't intending to lose if something else is going on.

If you are 100% sure there is no data you wish to keep on disk5 then I confirm that what jonathanm suggests to do will be the quickest way to get disk5 back into a fully working state.

 

Done those steps and it's looking much better.

I can now write small files to the array without errors.

 

That seems to have solved the first two problems.

 

I've now setup a large copy job to run overnight.

 

thanks

 

I setup a 7TB copy job and it's been running for about 24 hours and has copied over 1.3TB of data without stopping.

It's reading from my Unraid server and writing to the Unraid server I was having trouble with.

Your solution seems to have solved it.

I'm very grateful, I've been battling this problem for months off and on.

Looks like I have a free paid support call up my sleeve.

 

Thank you remotevisitor, jonathanm and StevenD.
