Should I be using Unbound Python mode? Is it stable?

Mine seems to be fine.. SG-3100 21.05.1 UFS with DNS Reply Logging disabled in DNSBL.. Python mode btw..

I did some tests on a system with 60+ days uptime and setup unbound with python mode. This is what I see when running the iostat command:

@vjizzle Depends om how large your Sata SSD is.
It’s doing 330Kb writes pr. Second on average. That’s:
0,33Mb * 60sec * 60min * 24hours * 365 days = 10.4TB/year
If your SSD is 128Gb or bigger, it’s probably not an issue. But if it’s 32Gb Id think about it. 16Gb or smaller and I’d be very worried.

@keyser It is 120GB m2 ssd so I am safe I hope. I saw on Reddit that bbcan177 released a patch for the growing files on disk. I hope he can tackle the frequent writes as well.

0,33Mb * 60sec * 60min * 24hours * 365 days = 10.4TB/year
So, based on that formula, I would be using around:
0,05Mb * 60sec * 60min * 24hours * 365 days = 1.58TB/year
With these writes, do you think I should be worried with a 8 GB eMMC Flash ?

I wouldn’t. The 8Gb eMMC is rated at about 11Tb write endurance as far as I have been able to find out.
So you should be good for about 8-9 years - likely longer than your appliance will be in service anyways.

after the last update from pfblockerng, stats are worse than before, at least for me..

You can’t use that command since you rebooted only 2:21 hours ago. Is shows average since last boot, and your boot skews those Numbers massively. You need to run realtime i intervals to see Whats going on: “iostat -d 5 6”
Six intervals of 5 seconds -

So it seems that just changing from python to unbound and then reverting back to python mode fixed it.. at least now it's not showing unbound in top -m io anymore.. -
@mcury Those numbers also look fine. There’s no massive writing anymore. So you are in the clear :-)
