failed when syncing ubuntu repository

[r00t1900]

Env

• tunasync: 0.8.0
• tunasynctl: 0.8.0
• tunasync-scripts: master@7817785
• system: debian 10
• arch: amd64

• tunathu/bandersnatch: latest

Description

The tunasync worker always outputs errors like the following when mirrorred size reaches approximately about 200GB:

Currently I can not figure it out. Here are some related infos:

Appeal

• Please help me figuring out why would this happen. I would like to make a mirror from tsinghua mirrorred data, which is about 1.7TB. However, in this situation, with so many error occurs, the progress will be deadly slow.
• I would also like to figure out each params in manager.conf and worker.conf, as I could not find any description in this repository that can explain the meaning of each params. For example, in worker.conf, there are interval params exist in both [global and [[mirror]]. I could not understand the difference between them.
• Further more, in worker.conf, I don't even know why the section must be set to with double [ and ], is this a feature of Go?

Others

I could not analyze any useful information with them, except this:

grep -rn "error" ubuntu-r_2022-02-26_11_27.log.fail

1540:rsync: [generator] write error: Connection reset by peer (104)
1541:rsync error: error in socket IO (code 10) at io.c(829) [generator=3.1.3]
1542:rsync error: Error in socket I/O
1543:rsync error: received SIGUSR1 (code 19) at main.c(1458) [receiver=3.1.3]

[r00t1900]

something more about the commented content in worker.conf:

[[mirrors]]
name = "ubuntu-r"
#provider = "two-stage-rsync"
#stage1_profile = "debian"
provider = "rsync"
upstream = "rsync://mirrors.tuna.tsinghua.edu.cn/ubuntu/"
#rsync_options = [ "--delete-excluded" ]
#memory_limit = "1024M"
interval = 5
use_ipv6 = false

I firstly are using the commented configuration, which uses two-stage-rsync as provider. However it came out with the sync error described in this issue, so I try to change the configuration into the debian configuration, just use the rsync provider. But finally they almost came to the same result, mirrorring slowly when the size is above 200GB.

I guess it is because the interval is too small, and your server is banned because of too frequent connections.

I guess so too. So would you explain that the meaning of each params in worker.conf ? Since there are 2 interval params and concurrent. And what's your suggestion?

My network speed is approximately about 10 MB/s. Thank you~

Please refer to #123 (comment) for explanation.
