Hello, I’m starting to get a lots of these errors and not sure why/how to correct them so after any help please. Have a RPi4 with 4TB HDD and been running since December 2022-03-09T12:22:06.684Z ERROR piecestore failed to add bandwidth usage {error: bandwidthdb: database is locked, errorVerbose…

As said i am facing a similar problem. Main reason i think it is because i am using a SMR disk (4TB like you btw) which can’t handle the load. You can check by yourself: if this happens when you accept lot of concurrent requests. how big is the problem, i mean the percentage of the errors you are…

@tre4orbragg did you search similar reports from the forum? One that looks very similar is Database bandwidthdb is locked - #2 by SGC or Weird node behaviour - #16 by YourHelper1

Yeah but those didn’t have much clear direction in what to do. I’ve checked the database and now updated the config.yaml for the max connections to 20 and will see how that goes

Thanks, there have been a lot more errors but looks like a bit less by reducing the concurrent connections so playing with that to find a good balance with load and actually getting traffic still!

I’m using Toshiba 6TB HDD, encounter the same error. After add setting: # Maximum number of simultaneous transfers storage2.max-concurrent-requests: 20 Then it works! No more “Failed to add bandwidth usage” errors, no more node suspended. Also see: Your Node is Suspended nothing obviously wrong…

This is a bad option - it cancel customers transfers due to “node is overloaded” (this is what they can see). It’s not a recommended solution, it’s a workaround for weak devices and SMR disks. The better solution is to move databases to SSD disk: [image] Move databases on Windows st…

But not everyone has money to upgrade to 6TB SSD…

Only databases. They are (very) small. One other option is to add a configuration option for storagenode client to not create them in the first place, or create in-ram if some are needed to store transient data. I would not mind losing statistics I don’t look at anyway if that means not buying eve…

How? I see the storage dir contains many files, also many blobs, which one should I move? [Deepin 截圖_microsoft-edge_20230227161236]

Only *.db ones, however I wouldn’t recommend to use RAM to store them, or you need to use some scripting to copy them back to the disk before shutdown and copy them back to RAM before node start, seems complicated to me. If you do not have SSD, it’s fine too, it was just a suggestion on case if you…
