Change Mount Point from Read-Only

[Matt Lock]

Hi,

I have a mount point set against a plex jail (11.2-RELEASE-p9 ). Its currently set to read only. I want to change this to allow changes, but when I untick the read only option and click save, I get an error saying "[EFAULT] Destination: /mnt/vol1/iocage/jails/plex/root/media already exists!" I have stopped the jail, btw.

Here's the error log. Any suggestions? Do I need to delete the mount point and recreate it?

HI, I see this bug has now been closed as it was discovered in a previous escalation. Can someone tell me if removing the Mount Point and recreating it (as not read-only) will be ok? Or will it still error that the mount point still exists? Read-only is causing many issues with Plex and I'd like to change it. Thanks.

try: iocage fstab -e yourjail
and change ro to rw
(save, quit vi, standart editor is vi if not set setenv to another editor

if this does not solve the problem delete the whole entry
(save, quit vi) and recreate the mountpoint rw

Fantastic, worked a dream. Thank you!
