Deleting the old release version

Inxsible · Jan 31, 2019

I am trying to delete the old 11.1-RELEASE version from my iocage download & release folders. For this I tried

Code:

iocage destroy -r 11.1-RELEASE

However it resulted in telling me that 2 of my jails are dependent on that release even though I have upgraded those jails to 11.2-RELEASE
Why is it warning me about the jails depending on 11.1 even when they have been upgraded?

Code:

root@nas:/mnt/tank/home/inxsible # iocage list
+-----+--------------+-------+--------------+-------------+
| JID |     NAME     | STATE |   RELEASE    |     IP4     |
+=====+==============+=======+==============+=============+
| 40  | couchpotato  | up    | 11.2-RELEASE |  |
+-----+--------------+-------+--------------+-------------+
| 42  | emby         | up    | 11.2-RELEASE |  |
+-----+--------------+-------+--------------+-------------+
| 43  | radarr       | up    | 11.2-RELEASE |  |
+-----+--------------+-------+--------------+-------------+
| 21  | transmission | up    | 11.2-RELEASE |  |
+-----+--------------+-------+--------------+-------------+
root@nas:/mnt/tank/home/inxsible # iocage destroy -r 11.1-RELEASE

This will destroy RELEASE: 11.1-RELEASE

Are you sure? [y/N]: y

11.1-RELEASE has dependent jails (who may also have dependents), use --recursive to destroy:
  emby
  transmission

root@nas:/mnt/tank/home/inxsible #

emby and transmission jails were created using CLI under 11.1-U5 whereas the couchpotato and radarr jails were created under 11.2.

although during upgrade of emby and transmission I do get the following

Code:

root@nas:/mnt/tank/home/inxsible # iocage update transmission
Snapshotting transmission...
Updating plugin INDEX...
Removing old pkgs...
Installing new pkgs...

Testing SRV response to iocage-plugins
Testing DNSSEC response to iocage-plugins

Installing plugin packages:
  - net-p2p/transmission-daemon...
  - www/transmission-web...
Updating plugin artifact...

Branch 11.2-RELEASE does not exist at https://github.com/freenas/iocage-plugin-transmission.git!
Using "master" branch for plugin, this may not work with your RELEASE

transmission has been updated successfully.

Note the bolded italic line. (emphasis mine)

Would using -recursive flag be safe? I really don't want to have to recreate my emby jail -- it's a pain to research all the meta data for my movies all over again.

It seems pretty clear that recursively deleting your 11.1-RELEASE would delete some of your jails.

Iocage jails are zfs clones from a snapshot of the release jail they were created from. It appears that using zfs promote can break the dependency, allowing the release jail to be deleted.

I know that but I have upgraded all the jails to 11.2-RELEASE as shown by iocage list. so why would there still be a dependency to 11.1-RELEASE?

calling @dlavigne or any other experts

meku · Feb 4, 2019

The dependency is not in iocage, it is the underlying zfs datasets.

When you first created the jail it cloned the 11.1-RELEASE be your jail. Later you upgraded the contents of your jail to 11.2-RELEASE but the zfs dataset is still a dependent clone of that original 11.1-RELEASE. Read the Docs about zfs clones and their usage.

Inxsible · Feb 5, 2019

Ok, so how would I upgrade the ZFS dataset to 11.2-RELEASE? By upgrading the ZFS dataset, would it then be possible to break the dependency of the jail on a particular release version?

I never updated this thread --- but here's what I did thanks to @meku

Here's my zfs list before I did zfs promote

Then because it was complaining that emby and transmission were dependent on 11.1-RELEASE, I promoted tank/iocage/jails/transmission/root. Promoting tank/iocage/jails/transmission gave an error indicating that the jail was not a clone

Code:

root@nas:/mnt/tank/home/inxsible # zfs promote tank/iocage/jails/transmission
cannot promote 'tank/iocage/jails/transmission': not a cloned filesystem
root@nas:/mnt/tank/home/inxsible # zfs promote tank/iocage/jails/transmission/root

Once I did that, I thought of trying to destroy the 11.1-RELEASE . I was expecting that it would now only complain about emby being dependent on that release since I had promoted the transmission jail. However it just went ahead and destroyed the 11.1-RELEASE.

Code:

root@nas:/mnt/tank/home/inxsible # iocage destroy -d -r 11.1-RELEASE

This will destroy RELEASE: 11.1-RELEASE

I achieved what I wanted, but I am not sure why it kept saying that both emby and transmission were dependent on 11.1-RELEASE, but then allowed me to destroy the 11.1-RELEASE only after promoting the transmission jail. Oh well !

f00b4r00 · May 10, 2020

I'm resurrecting this thread as I stumbled upon the same question/problem while wanting to free my pool from the 11.2-RELEASE after moving to 11.3, and it turns out that the post above probably didn't do what @Inxsible expected: as evidenced by the last output of zfs list, no space was freed from the pool.

If I read the doc properly, zfs promote simply reverse the clone and source relationship: the jail becomes the source and the clone can be removed, but this is purely cosmetic: the jail still depends on the data that was in the previous release.

From my very limited understanding of iocage operation and interaction with zfs clones, what would be needed for this to work correctly is for iocage upgrade to basically "rebase" the upgraded jail onto the new release, i.e. to make it a proper clone of the new release, so that all ties to the previous one are severed. I'm not sure if that's what it is supposed to do (it looks as if it were instead upgrading the jail "in place"), but as evidenced in my failure to remove 11.2-RELEASE despite upgrading all my jails to 11.3-RELEASE, it doesn't work.

HTH

EDIT: I reinstalled my jails from scratch on the new release, and deleted the old jails from the GUI. After doing that, iocage destroy -R -f -d -r 11.2-RELEASE would now complain that the old jails where not found. It turned out that this was due to snapshots still being there. Which makes me wonder if the upgrade was in fact correct in the first place and iocage destroy was simply complaining about these snapshots in a very non-obvious way.

Inxsible · May 11, 2020

When I upgraded from 11.2 to 11.3 and then to 11.3-U2, all my jails were upgraded correctly in that I don't have the 11.2 entries in my zfs list at all without me having to intervene.

I believe that it was a bug that was fixed between 11.1 and 11.3

itet · Aug 19, 2020

I upgraded from 11.3 to TrueNAS 12.1 BETA2. I also upgraded all jails to new release but I cannot clean my system to delete old jails because of dependencies and jail not found.

Code:

root@TRUENAS01:~ # iocage destroy -r -d 11.2-RELEASE
This will destroy RELEASE: 11.2-RELEASE

Are you sure? [y/N]: y

11.2-RELEASE has dependent jails (who may also have dependents), use --recursive to destroy:
  nextcloud
  plex
  rslsync

Code:

root@TRUENAS01:~ # iocage destroy -r -d -R 11.2-RELEASE

This will destroy RELEASE: 11.2-RELEASE

Are you sure? [y/N]: y
jail '  nextcloud
' not found!

@itet any updates on that, have the same problem.

You need to delete the snapshots for absent jails first (using CLI or Storage/Snapshots)

ChrisChros · Nov 8, 2020

OK after deleting the related snapshots I am still not able to delete the dataset for the old releases

Did you try the zfs promote commands that I have listed above ?
