Running the script from another volume? #5

Open tchit opened 6 days ago

tchit commented 6 days ago

Hello, My DS720+ drive is corrupt and in read-only.

I would like to save my Docker configurations for convenience and it is my understanding that it’s all in /volume1/@docker/

My issue is that when using SSH and sudo -i to access this folder, when I use the ls command to see the folder’s content I am met with this error when I enter /volume1/ :

Ls: reading directory « . » : Input/Output error

Someone told me about this script and it looks like it does exactly what I need in terms of saving all docker configs but I can’t install it on the Volume1 that holds my docker content since it’s read-only. Is there a way to start this script from another volume?

thanks

You can run the script from a USB drive or thumbdrive.

sudo -s /volumeUSB1/usbshare/syno_docker_export.sh

Docker or Container Manager needs to be running for the script to work. Is Docker or Container Manager running?

And you'd need to edit line 70 to change it from this:

    ExportDir="${DockerShare}/docker_exports"

to match your USB1 or USB2 etc like:

    ExportDir="/volumeUSB1/usbshare/docker_exports"

You'd also need to backup your docker shared folder, which is usually /volume1/docker if you don't already have a backup of it.


Do you have snapshots enabled?

ls: reading directory « . » : Input/Output error or ls: reading directory . : Input/Output error can be caused by a hardware issue (damaged RAM or hard disk). It can also mean a damaged file system or a driver bug.

Is the system partition read only as well? Does ls /var/packages work?

Thanks for your answer. Unfortunately Container manager isn’t running. I guess I need to find another solution, if there is one…Next time I’ll do backups with your script!Le 13 oct. 2024 à 02:42, Dave Russell @.***> a écrit : You can run the script from a USB drive or thumbdrive. sudo -s /volumeUSB1/usbshare/syno_docker_export.sh

You can run https://github.com/007revad/Synology_app_mover v3.1.60 from a USB drive and backup Docker or Container Manager to the USB drive. You'd need to have enough space of the USB drive.

Wow will try that tomorrow! Thanks a lot Le 13 oct. 2024 à 07:54, Dave Russell @.***> a écrit : You can run https://github.com/007revad/Synology_app_mover v3.1.60 from a USB drive and backup Docker or Container Manager to the USB drive. You'd need to have enough space of the USB drive.

I would suggest using a Linux computer, or Linux boot disk, to format the USB drive in btrfs. If it's not btrfs important information may not get backed up, or the backup may fail with error saying failed to backup @docker.

I have disabled my raid setup and have a volume2 with a clean DSM install. I suppose I can do the operation from that volume?Thanks a lot Le 13 oct. 2024 à 08:13, Dave Russell @.***> a écrit : I would suggest using a Linux computer, or Linux boot disk, to format the USB drive in btrfs.
