Jail Permission errors (read-only file system?)

[Keyakinan]

Hi,
So I can't access my jails from the shell anymore.

Can't change permission because its a read-only file system.

I'm not sure how to debug this or what is happening.

Also things like
$ sudo mount -o remount,rw /usr
Doesn't work because root hasn't got permission to execute these commands..

Help would be much appreciated!

You shouldn't be changing permissions on your jails, you'll break them.

 

[Keyakinan]

Thanks! Keep that in mind, next time I break them

 

[Keyakinan]

I'm fully stuck, no idea how to debug this or go any further..

 

[Keyakinan]

Do I just keep bumping this or can someone point me in a right direction..?

Have you try using jexec?
you can look at 14.3. Creating and Controlling Jails in the 14.3.2. Configuring the Host.
There are some examples on how to access the jail. If something fails the error will be printed to the console.

Hopes this helps a bit.

First of all, thanks for your reaction!
I've read a bit about it but I see no resolution for my problem..
I'm still locked out of all my jails and nothings works anymore..
I really don't want to reset all my jails but maybe I have to..

Is there a folder that I can copy to safe all my config ect?

It is always my pleasure!
What you can do is see if you can navigate to the directory.
Keep in mind I am thinking you have the pool mounted in /mnt dir.
For instance:
ls -ltr /mnt/Pool-ada1/iocage/jails/plex/ /
Since it is read only you should be able to read the files on the given location.
From there you ca:
cp /mnt/Pool-ada1/iocage/jails/plex/* /mnt/Pool-ada1/[New_Files_Location]
Keep in mind that in *nix everything is consider a file.

Woulnd't this also copy the read-only files or permission stuff? Then I prob would have the same error

When copying files from one location to the next, the files usually inherit the permissions from the parent container.
Adding to this, the files will be outside the container and you can manipulate the ownerships and permissions with chown and chmod respectively.

Inside the jail is different since the jail root owns all the files, contrary to outside the jail, the root user of the destination folder will own the directory and the files in that directory.
chown -R root:root /mnt/Pool-ada1/iocage/jails/plex/
chmod -R 766 /mnt/Pool-ada1/iocage/jails/plex/

I would recommend to run the following making sure there are not flags sets on the files:
ls -lo /mnt/Pool-ada1/iocage/jails/
