Re: Degraded NAS performance after kernel update

rpi-update jumped from 5.4.x to 5.10.x without ever having any kernel from 5.5 through to 5.9 available. So if you need something between those two kernel versions you'll have to build the kernel from source. I haven't had a chance to check but maybe rpi-5.9.y branch (commit ae39d1c) has been remov...

Re: Degraded NAS performance after kernel update

and this seems to be a niche thing. It's probably just other people may not have noticed yet / not care as much or are hoping for the standard kernel improvements over time, which generally come along. Such a performance reduction will have a much lower priority at the moment with everything else t...

Re: Degraded NAS performance after kernel update

I don't think 5.8/9 were available, at least I only noticed the jump from 5.4 to 5.10 No you'd have to specify it possibly by a commit reference but I've not sure, they were available and would hope they still are as I was running 5.9 prior to 5.10 :) But you're now starting to reach the rim of my ...

Re: Degraded NAS performance after kernel update

Initially my final throw of the dice ..... (yes I agree that sounds strange) With a base system fully updated which I assume will give you a 5.10.x kernel (not sure as I run the beta software) you could use I believe rpi-update to downgrade just the kernel and it's support modules to a prior 5.4.x v...

As your drive is being seen as a "uas" capable device, as long as it isn't requesting too much power, more than the Pi USB3 port can deliver, you may be trying to deal with a USB to drive interface controller compatibility issue. In the debug, idVendor=0781 this is listed as SanDisk, so pr...

Re: Automated microSD dump over the network

For a starting point you could use one of RonR's scripts - image-backup - this would create a full backup of the microSD card to a mounted network share. This would satisfy part of your requirements. You'd just need to script it with a cron job, from experience it works really well. Here's the link ...

Yes, exactly this.

If you install and monitor "bcmstat" what does that display while your Pi4 idles and then while you stress your Pi4 with doing stuff - do you see the reported arm frequency vary etc.

Unless you are booting from USB the fix doesn't change anything. If you are booting from USB you should have said so.
