BOOT-Pool continuos writing [HELP]

[Davvo]

Pretty sure you do.

To remove the swap from the boot drive need i to reinstall TN ?

this is my "Init/Shutdown Scripts"

Code:

#!/bin/zsh

swapon -p 0 /dev/nvme0n1p1
swapon -p 0 /dev/nvme1n1p1
swapoff /dev/dm-0
swapoff /dev/dm-1

if you want to check current swap info

Code:

swapon -s

After much hesitation I managed to convince myself to do the reinstallation.
I thought the re-import procedure was much more complicated and required reconfiguring the dockers and vms.
I found some free time to do the work and after a somewhat long first start I reloaded the configuration and everything works properly
Writes seem to have decreased 10x

running the command: Sudo swapon -s
Nothing comes out, does this mean I don't have any swap partitions?

Writes seem to have decreased 10x

nothing, I still have 100kbs of writes on the boot disk

I thought I identified the cause:

BOOT-Pool continuos writing [HELP]

If you run the script using -dump email it will email me a copy of your drive SMART data and I can look into it. Done As for your original problem, have you looked into your SWAP file? Is any being used? If yes, then where is your SWAP file located? when i run htop, no swap is used And...

Reinstallation will not fix this. TrueNAS SCALE simply does write to the boot pool continuously.

100 kBytes (? - you write "b", ist that bytes or bits?) per second sums up to 3 TB per year. Nothing to worry about.

100 kBytes (? - you write "b", ist that bytes or bits?) per second sums up to 3 TB per year. Nothing to worry about.

sorry my mistake, 150 kByte/s (capital "B"), it is slightly more than the last reading. but probably because before there was empty space in the graph due to the reboot

150.000 B/s * 60 * 60 * 24 * 365 = 4.730.400.000.000 B = 4.73 TB/year

which for an SSD (even a small one) isn't much but it's still 5TB of what? log ?

In the ticket I opened the devs blamed swap but now it's not there!

 

[Patrick M. Hausen]

If I am correct it's netdata logging the middleware accessing netdata.

 

[Davvo]

Over 4.5TB/y is significant imho, especially since most SSDs have a TBW between 4 and 4,5.

 

[ThEnGI]

I'm using a cheap (not major brand) 128GB Sata SSD, is advertised for 80 TBW.

Will they be real?

Which in any case even if I change it every year it's still "only" €20, which I still don't like anyway it seems absurd to me to change the boot disk to reach the TBW

 

[Patrick M. Hausen]

Over 4.5TB/y is significant imho, especially since most SSDs have a TBW between 4 and 4,5.

Transcend 370S series 32 G model is specified at 90 TBW. Typical prosumer SSDs by Samsung come in at 600 TBW and higher.
The drives with the lowest endurance I use are Supermicro SATA DOMs: 34 TBW for the 32 G model.

I agree that IX should fix that unnecessary logging.

 

[Davvo]

Uh... maybe I forgot a couple of 0? Though I was sure I had seen a 4TBW somewhere. Well, it's better this way.
That's what I get for not double checking the numbers in my brain!

Yes!

This is my boot-pool:


Maybe new version can fix your problem
