How to delete old Truecharts apps and associated files?

Apps and Virtualization
1

Hi I finally migrated to Electric Eel and then decided I don’t need the last couple of Truecharts apps.

I know how to delete the datasets I created for them but where do I find and remove all the app folders and files and images related to these two TC apps?

I had installed Truecharts COPS and Openbooks which I have replaced with Calibre-web.

Thanks everyone

I guess (with some confidence, but not 100%) that the update process will move only the supported TN catalog apps from the old ix-applications to the new ix-apps dataset.

So once you are confident everything works as expected, just nuke the entire ix-applications thing.

Hi, thanks for replying. How do I tell if all my ‘wanted’ apps are in the .ix-apps folder? I’ve gone in there and see a load of folders but not sure how to determine everything is there.

I am sure you are very accomplished but I don’t want to nuke my life long work on FreeNAS/TrueNAS! (well almost 10 years)

Actually I do see app folder names in the app configs and mounts folder

EE does not use anything but ix-apps. That ix-applications is dead as far as EE is concerned. My “not 100% sure” was more about “maybe it did copy some things over that you want gone”. I am 100% sure that ix-applications can go.

Just in case you later discover that there might be data in there you wanted to keep, do a backup of the complete thing first.

I don’t have a Cobia installation accessible anymore, but assuming the dataset is mypool/ix-applications a rough outline:

zfs snapshot -r mypool/ix-applications@backup
zfs send -R mypool/ix-applications@backup | gzip -c > /mnt/mypool/path/to/some/dataset/ix-applications-backup-20250209.gz

That file can be used with zfs receive to recreate whatever structure was in there in some convenient place to examine the content. The gzip is not strictly necessary because ZFS will compress by default, but in case you want to copy it off to e.g. an external medium with FAT32 or Ext4, the file being compressed can be handy.

HTH,
