So I am running my 16TB node off of my rpi 4 8GB (USB 3.0). The OS, DB, and identities are on an SSD (USB 3.0). I have 2 USB 2.0 ports left. Will the pi 4 8GB be powerful enough to handle another 16TB node once this one is full? In terms of powerful enough, I mean the CPU, USB bandwidth, and USB 2.0…

Why don’t you try it out and let us know? Now is a good time, you’ll start getting a lot of traffic from Salt Lake as soon as you spin it up (the vetting requirement has temporarily been removed on that satellite whilst network performance testing is ongoing) Sounds like a bit of a Franken-node to …

I was thinking about migrating my node to a pi5 with 8GB RAM to reduce electricity costs. Now that the code is more optimized that might be possible. I have one concern. How do you all speed up the file walker? Currently I just finish any filewalker process in minutes thanks to ZFS. The Pi5 doesn’t…

I reduced retain.concurrency to 1 and enabled lazy filewalker. Seems to be coping just fine. Gets a bit hammered during garbage collection, but most of that is IOWait from the USB spinning rust. The nodes I have running on Pi5s with SSDs are doing perfectly fine (will never turn a profit but I have…

I’m running 3 nodes (1.7TB, 1.7TB, and 6TB) on a RPi3, the 4 and 5 should be more than capable of a second node. This is also just running each node on individual HDDs and everything else on the Pi’s MicroSD. The 1GB of memory on the RPi3 is probably the main bottleneck, followed by the SATA to US…

I have 2x 10 TB running on a Pi4B with 4 GB and struggling with file walker . That must be due to RAM and USB limitations. It’s a mess, but I’m not convinced to invest in new hardware.

So you think a pi 4 8GB would be able to keep up with 2x 16tb drives?

Compare USB specs - if they are similar : NO.

On my Syno 1GB, these impruvements work: disable lazzy FW; run FW only once and than disable it; ext4 + noatime; move db to USB flashdrive; use custom log level to reduce noise; if you want to speed FW run, you can reduce the allocated space to stop ingress. I didn’t tried changing concurencies, b…

What do you mean? For USB on the pi 4 I have the following: 2x USB 3.0 2x USB 2.0 OS and DB drive (SSD): plugged into USB 3.0 16TB Node: plugged into USB 3.0 2x USB 2.0 ports remain.

The Pi is limited to 10 MB/s transfer rate, on USB3. I do not have it at hand, but that’s an issue.

Multiple nodes on a raspberry pi 4?
