Hi, I installed a new SSD for external data.
I ran the migration process from the GUI and everything went well.
Now I'd like to see if the trim on Home Assistant is working.
The disk trim is enabled.
I have a raspberry Pi400 with HAOS installed

Please share lsblk -Do+FSTYPE,MODEL.

i think, reading online, that i am ok and from now there is a scheduler for trim

steady current
#

Ah, try apk add lsblk first then.

#

Seems like it works. Please use three backticks to format the text so the formatting is preserved and it's readable.

To format your text as code, enter three backticks on the first line, press Enter for a new line, paste your code, press Enter again for another new line, and lastly three more backticks.
```yaml

Don't forget you can edit your post rather than repeatedly posting the same thing.

systemctl status fstrim.timer should tell you about the trim job.

#

Interesting choice of drive for a pi. I have some of those myself.

molten fjord
#

I used mmc for OS and external SSD for data

steady current
#

It's interesting because it's a datacenter SSD. Personally I'd just use the SSD for all if possible.

molten fjord
#

one question.
to use the trim command i did this command
docker run --rm --privileged --pid=host -it alpine:latest nsenter -t 1 -m -u -n -i sh

#

it's right?

steady current
#

Yeah that's what I linked.

#

That's just to get to the real OS' CLI to test things,

molten fjord
steady current
#

Yeah. Fstrim usually runs weekly.

molten fjord
#

because if i do docker ps on ssh i don't see alpine latest image

steady current
#

docker ps shows running containers, not images.

molten fjord
steady current
#

docker images.

#

But why?

molten fjord
#

ok

molten fjord
#

but where i can see the ftrim services?

steady current
#

I told you, run systemctl status fstrim.timer after getting into the OS' CLI.

#

This docker container you start does not really run anything. It's just a way to get into the OS' CLI. It will stop and be removed once you exit.

molten fjord
steady current
#

No. This is just so you can see that this timer exists and works. You don't affect anything by doing this.

#

Well, if you run fstrim -av you do, but this was just to test. The timer does this weekly as mentioned.

DC drives like yours can usually deal fine with not being trimmed, by the way 🙂

molten fjord
#

so on 30th December i will check

molten fjord
#

Thank you for your help

steady current

No problem.
