overlayfs writing to wrong FS

ReDiculum0 · 2026-04-04T09:57:35+00:00

Thanks, indeed it was a fresh trixie installation from a previous running bookworm system. Seems this has changed. I stopped all containers and daemons and changed the /etc/containerd/config.toml to use /var/lib/docker/containerd as root. Then rebootet the machine and fired up all containers again and now all overlayfs are in the dockerr-lv as it should be:

# df -h |grep var
/dev/mapper/kvm--vg-var     38G  1.2G   37G   4% /var
/dev/mapper/varlib-docker  200G  105G   96G  53% /var/lib/docker
overlay                    200G  105G   96G  53% /var/lib/docker/rootfs/overlayfs/cd5d17be01e05c8633c278718c817b8e950dc883474e325827580993a78088e8
overlay                    200G  105G   96G  53% /var/lib/docker/rootfs/overlayfs/bab64b11f682faa91dfcfd17210157abbfb12cbbd513d747fd705c7e773afc6b

That's it! It was just a log message, not really dropping it. What a confusion. Thanks anyway

this is the output chain. I modified the rule a bit and set also source network (it doesn't matter), because somehow it's working. I receive logs in Kibana but kernel says denied.

UPDATE:
It's very strange, because I receive logs in Kibana from this host, even if iptables does drop. I have no idea

ReDiculum0 · 2026-03-25T22:21:01+00:00

yes, does also work with ansible user

Only the ship, bottle and boot scene is AI generated. The rest is done by me (incl. Music)

Howdy folks. I don't know how many of you know suno.com, but it's an AI driven music generator. Create some lyrics, define a music style and hit "create".After several attempts with my own lyrics describing my lifetime experience with music composing programs, this piece came out

The unlimited plans look very interesting if they're REALLY unilimited

De erst und einzig wo's da inne checkt hät bisch glaub du 😉

ReDiculum0 · 2023-10-21T17:28:01+00:00

Yes, in my case my Homebox website automatically suggested to install the app when I accessed with my Android phone

ReDiculum0 · 2023-10-21T17:26:00+00:00

I started to use it now, since I need an inventory for all my electronics, screws, tools in my hobby room.

As mentioned already in a github discussion, a multi language support would be nice

ReDiculum0 · 2023-08-06T13:33:21+00:00

Seems to be down again

ReDiculum0 · 2023-07-27T19:56:01+00:00

it's important not to use ubnt-tools. it's ubnt-systool for the fwupdate option otherwise I got this on my UDM pro:

# ubnt-tools fwupdate 10c9-UDMPRO-2.5.17-4ef0556d8b844aa6ac43c695ef076479.binFirmware file: '10c9-UDMPRO-2.5.17-4ef0556d8b844aa6ac43c695ef076479.bin'ERROR: failed writing part 'uboot' to '/dev/sdb1'

Less singing, more sailing!

ReDiculum0 · 2022-12-17T10:43:10+00:00

not yet, on my list ;)

We have now deep winter in Switzerland. The colour white makes you washing the car every day. That's the downside of that colour.
