Re: 64-bit EXT4: breaking the 16TB limit

That's good news. Those USB enclosures sound interesting. Would you mind telling the manufacturer and model number? Was there any reason you chose them over similar ones? Just some very old StarTech units, they're so old they only have USB2, but they also have E-SATA multipliers which is why I boug...

Re: 64-bit EXT4: breaking the 16TB limit

There are reports that the Raspberry Pi hardware is only able to deal with 6 high-speed USB2 devices at a time. Assuming your RAID6 24TB array is in the form of five 8TB drives or six 6TB drives things should be fine. However eight 4TB drives may not work out so well. I'm not sure if the presence o...

Re: 64-bit EXT4: breaking the 16TB limit

To use a 24 terabyte RAID6 array, it might be expedient to boot a fully 64-bit operating system. I would start by experimenting with this 64-bit Gentoo image, which has had some pretty positive reviews. Ah Gentoo, haven't used that for probably 10 years, that will be interesting to have a poke at a...

Re: 64-bit EXT4: breaking the 16TB limit

Sorry but this is getting a little off the original topic (I've done BTRFS RAID in the past, not going there again), I'm looking to see if anyone has any experience with firing up large EXT4 filesystems on a Pi, it looks like a "no" at the moment, I'll play around with it a little more and post back...

Re: 64-bit EXT4: breaking the 16TB limit

Are you mounting your 24TB array as an iSCSI device? No, it's hung off the back in two USB JBOD containers, one of the tests I'm doing is to see if the Pi's USB is solid enough to keep the array together, for a Pi 2 the answer is no, but the Pi 3 has written 6TBytes and only broke up the array once...

64-bit EXT4: breaking the 16TB limit

Morning folks, I have some old pis hanging around and the need to create an occasional backup system for relatively non-vital backups, and my old 24TB RAID array now going spare and unused. So I thought I'd get one of the Pis to do backups over rsync to the array. It would be slow, limited mostly by...

Re: PoE HAT - USB Ports not working - over-current

How can it be 'tried and tested for 3+ years', when the Pi3b+ - the only Pi you can power via POE, has only been out for about half a year? Their hat powers other pis, it doesn't rely on the new features of the Pi3B+, so it's not as neat, but it does work, which currently the official hat doesn't. ...

Re: PoE HAT - USB Ports not working - over-current

Can you please provide guidance if we should RMA our hats now or wait until you figure things out? I don't want to swap mine out for one that has the same issue, but I also don't want to be told that I have exceeded the return window.... Yes that would be handy, I've already applied for my RMA (abo...

Re: PoE HAT - USB Ports not working - over-current

If it doesn't work without a fudge then it's more expensive but more of a fudge than a cheap POE splitter, I wanted it as a neater alternative but as it's now turned out to have significant disadvantages over a POE splitter and no real advantages, I can't see any reason to keep it or recommend it. I...

Re: PoE HAT - USB Ports not working - over-current

Personally I don't regard this as a fix, so will be sending my hats back as faulty for a refund when I get back from this work trip and will go back to using cheap splitters at a fraction of the price but without the reliability problems. I'm surprised something this bad got released.

Re: PoE HAT - USB Ports not working - over-current

After getting "over-current change" errors on the first pi when copying from the SD card to an external *powered* disc, I tried it again on different hardware. On the second Pi and PoE hat (I have two new Pis and two new PoE hats) I first tried copying the root filesystem (rsync -ax / /mnt/test/root...

Re: PoE HAT - USB Ports not working - over-current

I've just had a powered external hard disc booted off my pi in the middle of a big copy with "over-current change" reports in syslog. Annoying. I'll do some switching around later to see if I can narrow it down as I have two new Pis and two PoE hats to play with.

Re: Official PoE HAT: two of them, running hot

OK, I guess I'm not used to running the 3B out of a case, since posting I disconnected the hat from one of the 3Bs and powered it off the official PSU, still connected to the network via ethernet, and it's still running at about 40-45 so it looks like it's just me being jittery.

Official PoE HAT: two of them, running hot (nope, just me being daft)

Hello all, I got the new Hat yesterday and two Pi 3B+'s arrived today. Connected them all up, downloaded fresh Raspbian, booted up, ran an update and dist-upgrade. Works fine but I was surprised at how hot the Pi and the Hat are, despite there being no software load and no extra hardware plugged in....

Hello all, I've been using this setup for a little while now and I'm pleased with it, but there is a niggle that I am going to have to work around, I just thought I'd check I'm not missing anything before I do so.
