If anybody else wonders how to do this. Syncthing has guidance in their FAQ: https://docs.syncthing.net/users/faq.html#how-do-i-rename-move-a-synced-folder Important: Be very careful, have backups ready, wait for all syncing to complete on all devices, etc. Specifically the following worked for me:

Thanks for the quick answer! Ufff, I didn't quite realise that Disk 1 was not even showing temperature anymore.. I stopped the array, shutdown (this did not do anything, so I tried powerdown via the GUI bash). GUI went offline, but server stayed on, so I held the Power for 3+ seconds. Opened up the server and it seemed mostly fine. Maybe one of the power cables came loose? Now, back up, parity checking without errors and the shares are back. Let's see what happens, but it looks good so far! Thank you again!

Last parity check was without issues. Unraid 6.9.2 - running for a couple of months. 1x18TB parity drive 1x18TB and 2x14TB data drives No hardware changes since last parity check. What happened: After running the parity check for a while, I noticed the amount of errors - in the millions and running up between Parity and Disk 1. Paused the parity check. Read errors on the parity drive kept running up. They seemed to run up continuously. One disk (one of the 14TB) also shows UDMA CRC error count 1. Some of my shares already show as empty or with much reduced content, although they shouldn't be. At this point, I am not sure what to do but slightly panicking. Could this be an issue with the SATA controller? Why would it develop suddenly? Ambient temperatures are relatively low. Also, is there any way to recover data and/or prevent further data loss?
