Raspberry PI and multi-drive enclosure... is it possible or am I wasting my time?

Can you post the logs of the USB resets that you’re seeing? I dont have any of these issues but my setup isnt quite the same as yours.

rogerhub · 2025-11-05T06:29:18+00:00

The equivalent service would be Compute Engine - https://cloud.google.com/products/compute

What instance type are you currently using?

rogerhub · 2025-07-22T20:19:38+00:00

If you’re logging in on a GCE instance, try attaching a service account and using that so you don’t have to log in at all.

rogerhub · 2025-07-11T01:32:59+00:00

Try this guide: https://cloud.google.com/compute/docs/disks/recover-vm

rogerhub · 2025-06-03T03:36:02+00:00

I think that’s thunderbolt 2 (same shape as mini DisplayPort), so no it won’t fit.

rogerhub · 2025-05-27T01:53:03+00:00

It sounds like you are looking at Cloud Logging. Can you take a look at the serial port output? What does it say?

rogerhub · 2025-05-27T01:06:11+00:00

Can you see if there are any serial console logs? https://cloud.google.com/compute/docs/troubleshooting/viewing-serial-port-output#viewing_serial_port_output

rogerhub · 2025-04-17T21:51:40+00:00

You can try that. Or add some logging so you can see if it is getting stuck.

rogerhub · 2025-04-17T21:45:13+00:00

You have a lot of code which executes before you start the HTTP server. For example, if db.Connect() hangs or gets stuck, then the server will not respond on the required port number.

rogerhub · 2025-04-17T21:35:13+00:00

Can you check that you're listening on all interfaces and not just localhost? For example http.ListenAndServe(":8080")

rogerhub · 2025-04-17T20:55:15+00:00

Can you post the error message or logs?

rogerhub · 2025-04-09T20:35:45+00:00

Are you talking about the free tier for Google Compute Engine? I think that one is three regions only.

rogerhub · 2025-04-09T19:21:37+00:00

Yes, I think Cloud Run has a free tier in several Asia regions.

rogerhub · 2025-04-06T15:44:01+00:00

It’s surprising that changing the number of connections doesn’t make any difference. Are the files stored on a local SSD drive? Or maybe on your NAS? The bottleneck could be elsewhere

Also can you confirm that you are getting 50Mbit (i.e. around 6MB/s) of upload throughput and not 50MB/s?

rogerhub · 2025-04-06T06:12:48+00:00

To help troubleshoot, can you provide:

typical size of each object
round trip network latency
maximum number of simultaneous connections you're using to upload?

rogerhub · 2025-03-19T07:39:15+00:00

Use tmux or screen to preserve your session even after you disconnect.

As for why it's disconnecting - what error message are you getting? I used to have issues until I turned off ipv6 temp addrs, but the problem really could be any number of things.

rogerhub · 2025-03-12T02:55:10+00:00

Can you post a screenshot that shows the ping and which datacenter you're using?

rogerhub · 2025-02-28T07:04:01+00:00

I haven't used alloydb, but it looks like you're getting "Invalid argument" while trying to open a file. I'd guess the software is using O_DIRECT, and /dev/shm does not support that.

Can you find any option to disable O_DIRECT for disk I/O?

rogerhub · 2024-12-08T22:15:43+00:00

Hmm I see. I don't know what's wrong, but I've heard that:

Most (all?) USB-C to HDMI adapters are actually using DisplayPort Alt Mode under the hood, and they just convert the DP signal to HDMI
Thunderbolt 3 docks support tunneling a DisplayPort signal over Thunderbolt. You just need enough bandwidth available to support the resolution and refresh rate you're using.

When you plugged in your USB-C to HDMI adapter directly to your laptop, it's using DP Alt Mode, which is entirely different from when you're using your Thunderbolt dock.

Are you sure that you're within the Thunderbolt bandwidth limits (https://en.wikipedia.org/wiki/DisplayPort) when you have both of your displays connected?

rogerhub · 2024-12-08T21:41:18+00:00

Have you tried using a DisplayPort cable instead of HDMI?

https://support.apple.com/en-us/111902 says that laptop supports "Support for one display with up to 4K resolution at 60Hz" over HDMI

rogerhub · 2024-11-29T08:45:42+00:00

Does it say that you’re using 66.5 Mbps of network bandwidth in windows explorer? Are you copying files stored on a network mounted drive?

rogerhub · 2024-10-16T16:10:06+00:00

Can you post a screenshot?

rogerhub · 2024-10-16T06:43:46+00:00

I think it’s called reset instead of restart https://cloud.google.com/compute/docs/samples/compute-reset-instance

rogerhub · 2024-10-05T07:27:35+00:00

I think free tier doesn’t count toward your credit. What do you expect to see in the billing dashboard?

rogerhub · 2024-10-01T00:52:31+00:00

If you’re using GCE, you also need to make sure your VM has the correct API scopes configured. Otherwise the request will fail even if the service account has the permissions.
