Hello:
I run a cluster of a couple of machines used for archives: users uploaded data onto one machine (“Master”), and this gradually synced to the other (“Slave”). Both machines ran in Send & Receive mode.
Unfortunately the Master suffered a hardware issue before the sync completed (there was a lot of data), so I had to pause the sync and manually transfer outstanding data across to the Slave, and then swap roles - the Slave was now being updated by users.
I’ve since resolved the issues with Master, and need to get it back in sync with Slave - but I’m nervous about just setting the sync just running again, in case the Master starts to undo (wanted) changes on the Slave.
What would you advise I do, prioritising safety of files on the Slave above all else? I’m considering two options:
- Remove the Folder from Syncthing on Master, actually delete the folder from the Master filesystem, then re-add the Folder into Syncthing on the Master. Will this result in Slave pushing all files onto Master, and prevent any deletions from pushing onto Slave?
- Set Slave Folder to Send Only and Master Folder to Receive Only, until they are both fully in sync. Presumably this will allow it to take advantage of the already-synced data, without needing to re-transfer it. At a later point, I can set them both back to Send & Receive if necessary (as there might be data uploaded onto both units in the future).
Any thoughts?
Thanks,
Pants.
