I have run these jobs many times in the past on the old unraid releases.

A week ago, I upgraded to the latest unraid release.  Not sure if this is related ?

I have a job that copied about 250GB of photos up to unraid if any differences.

There are large differences now as faces all written to the photo metadata.

If I run this robocopy job, the unraid server crashes in some way - I get alerts that my dockers etc are not responding.

Console access is frozen from attached monitor and over the network.

I can only click the reset button and get a parity check.

 

I just repeated this again and it happened.

 

I am now trying a manual copy with windows file explorer rather than robocopy script.  Will report back.

 

The diagnostics I ran afterwards the first time is attached if it is requested.

Caused it to all lock up again - however this time I was able to free this up by killing the file copy job from my pc.

I am now going to try my old free file sync app to see if that can work - it states there is only 65GB that needs replacing (31,035 files).

 

The freefilesync app allowed this to process without any unraid lockup.

I will use that for any mass updates from now on.
