4 years ago user can only be used with contracts that you formed with user. It can't use your siad contracts, unless you manually convert them. (And if you do, you won't be able to use them with siad anymore.) If you want to convert existing contracts, let me know and I will write a script for you.
Alternatively, you can form new contracts with user form and renew them with user renew. These commands will spend coins from your walrus wallet. You can choose which hosts to use by looking at siac hostdb -v or https://siastats.info/hosts.
If you have a walrus_addr and shard_addr in your config.toml, siad will not be used at all.
By the way, both shard and walrus store their own full copy of the blockchain. If you don't want to store two copies, you can use shard.lukechampine.com as your shard server.
I haven't tried storing a database with FUSE, so let me know if it works! If you truly want to "format your Sia hosts as ext4," you may need to use something like BUSE instead of FUSE. I would have to write a bit of code to make BUSE work with user, but I don't think it would be too difficult.

Dear Luke, I want to use "user" with walrus & shard for posibillity to automaticaly manage contracts from my siad. I want to try "user" with "fuse", but need automatically manage or use existed in siad contracts. 1) SIAD started and have contracts and some SC amounts. 2) # ./walrus -http 127.0.0.1:9999 Listening on 127.0.0.1:9999... 3) # ./shard -r 127.0.0.1:9385 2019/11/27 21:14:41 Listening on :8080... 4) config.toml for user siad_addr = "localhost:9980" min_shards = 10 shard_addr = "127.0.0.1:8080" walrus_addr = "127.0.0.1:9999"
5)# ./user mount /mnt/user_meta /mnt/user Mounted! Create 1.txt: minShards cannot be greater than the number of hosts - this happened when i tried to copy 1.txt to the mounted /mnt/user
Where is a problem in my configuration or somthing else ?
P.S. Repertory is very good idea, but have a problems with "file based cache" - it's not usable if you want to work with big files on fuse. Chunk based cache ofcouse will be better the file based cache. But main problem it's if i have big file, but want to modify small part of this file - repertory trying to reapload full file. If my file is 2 GB and I want to modify only several KB - I don't have a reason to upload 2 GB again. I hope that "user" provide me a posibillity to do this. It's a very great idea to move anytnig into SIA. For example I want to make some file with ext4 file system on fuse and the try to allocate traditional data base MySQL or MySQL Server in the blockchain.
Many thanks in advance.
