Enabling Large Blocks

[Moisie]

Hello:

I have a bunch of folders on many machines which are happily syncing - but without Large Blocks being enabled on them.

I’m considering enabling Large Blocks on these folders - which I presume brings increased efficiency in syncing and reduced database size. However, what should I be aware of when making this change?:

• I presume the folders will get completely rehashed - which will presumably slow syncing down for file changes whilst the rehash happens, and result in the re-exchange of all the indexes;
• I won’t be able to enable Large Blocks on all machines on a folder at exactly the same time. Will this prevent machines without Large Blocks enabled from receiving changes, until they have it enabled?

Anything else?..

Many thanks!

Everything will not get rehashed as a result of the change; only files changed afterwards will get the large blocks treatment.

Other devices can sync those files just fine regardless of their block size setting. However, the first time a file is synced with a changed block size it will need to be transferred in full.

Amazing - that sounds perfect.

Once more, I’m humbled by the depth of thought that goes into this project - thanks!
