Problem with rshared on fstab for mount / #5

Closed hugoleosp closed 3 months ago

hugoleosp commented 3 months ago

I've been trying to install HA for quite a few time now and I was following your tutorial and I wasn't getting any error from the steps provided but HA wasn't installing .. only one image on docker could be seen .. then checking the docker.log I was getting the following error:

"Handler for POST /v1.45/containers/hassio_supervisor/start returned error: path /usr/share/hassio is mounted on / but it is not a shared or slave mount"

And googling a solution I found that for an unknown reason my / wasn't being mounted with the shared flag even it's written in the /etc/fstab ... then I followed this guide and it worked:

https://ixday.github.io/post/shared_mount/

All I need to do was manually share the / with the following command: mount --make-shared /

Remove all the packages and reinstall them again .. and it worked =D

Thank you for all your effort .. thank you so much =D

This might be due to non standard configuration on your Alpine Linux. I'm using the same packages, it gets mounted by fstab and the flag is there.

It seems a non standard configuration like @kuba2k2 mentioned .. but I just followed the installation guide from Alpine official website. But maybe it's because it's installed as a virtual machine... but following the guide with the solution seems to have worked even after a reboot... so I just want to leave here in case anyone else face the same issue ..

Did you reboot after adding the rshared flag to fstab? Commands like mount don't propagate after reboots. If it still works after a reboot, it means that the flag in fstab works. So you probably didn't reboot after adding it.
