Description Oliver Falk 2020-04-23 12:05:53 UTC

+++ This bug was initially created as a clone of Bug #1705979 +++

Description of problem:
The  /var/lib/tftpboot/boot is growing a lot, it adds a lot of new files:
- The old files with the old naming convention are still kept, should those not be deleted if not used anymore?
- The files with the same content are not hardlinked taking up a lot of space.

Example:
    # du -h /var/lib/tftpboot/boot
    1.4G    /var/lib/tftpboot/boot

    # ls -l /var/lib/tftpboot/boot
    total 1365152

Version-Release number of selected component (if applicable): 6.5


How reproducible: Always


Steps to Reproduce:
1. Use deployment via TFTP
2. Check tftp/boot

Actual results:
Space wasted.


Expected results:
If there is no process to track if these files are still needed or not, there should be at least a process that does a hardlink run from time to time.
Is there a manual process that one can trigger to get rid of old files there?

Comment 3 Oliver Falk 2020-04-23 12:10:29 UTC

As suggested over in the other BZ, I'm opening this one in order to address/add the functionality to clean out old files in tftp/boot with satellite-maintain.

Comment 5 Lukas Zapletal 2020-04-27 09:33:11 UTC

To give you little bit more context:

Implement a command that checks if there are any /var/lib/tftpboot/boot/*-{vmlinuz,initrd.img} files older than two weeks (configurable via option). Provide a resolution (fix) - delete those files. Make this check to be part of the standard suite of checks. Note this directory can be missing if TFTP module is not set up - skip the check in that case.

Comment 6 Peter Vreman 2020-04-27 09:41:21 UTC

Lukas,

Deleting everything older than 2 weeks cannot be done, at least not what i quickly see as an user:

[crash/LI] root@li-lc-2222:
-------------

If you implement what you mentioned above to delete files older than 2 weeks then All files will be deleted and then any TFTP is broken until a build-pxe-default is executed and the boot images are recreated.

Peter

Comment 7 Peter Vreman 2020-04-27 09:52:17 UTC

And secondly the original issue is not only partly solved by cleanup of obsolete images.
Because after cleanup of all files (2.4GB) and then call to build-pxe-default to rebuild all TFTP images i still have 1.4GB of images:

Why do i have 5x the same image for red-hat-enterprise-linux-8-for-x86_64-baseos-kickstart-8-1-* without using e.g. hardlinking (the ls -l below shows '1' for files that have the same hash in column 2)?

Comment 8 Lukas Zapletal 2020-04-27 11:14:12 UTC

The reason why this is so clunky is because PXE handling is done by Foreman core while content handling (Content Views) is done by Katello plugin and this is not integrated deeply. Ideally, we would calculate SHA1 sum of the content and name files accordingly, problem is filenames are created by Foreman not Smart Proxy and without access to the content. Foreman would need to download them, calculate SHA1 sum thus filename and pass this to smart proxy. This seems to be too complicated. Thus the proper solution is to completely redesign this.

One partial solution could be that we keep everything (the API) as is but proxy would download and store files under their content hash name and create only symlinks pointing to these files. But then it's just a different problem - you would end up with many symlinks. Granted it wouldn't consume too much space then but with high rate of promotions you would still end up with many symlinks. A cleanup process would still be needed. Is your bigger concern the size or amount of files?

Now, you are right that I haven't considered hosts which are in build mode. But hosts are only valid for given amount of time (token duration) and they expire and the only way to get out of that is to exit and enter build mode which is a process which re-downloads TFTP files. Therefore I am going to update instructions for the foreman maintain team:

- Connect to Satellite API or DB and find token_duration setting (amount of minutes host provisioning tokens are valid).
- Implement a maintain command that checks if there are any /var/lib/tftpboot/boot/*-{vmlinuz,initrd.img} files older than N minutes (token duration setting found above).
- Provide a resolution (fix) - delete those files.
- Make this check to be part of the standard suite of checks.
- Skip this check if:
 - the TFTP directory is missing
 - token_duration is set to 0 (tokens are disabled)

I hope this creates better experience until we find time to redesign TFTP.

Verified:

Verified with:
- Satellite 6.8.0 snap 15
- rubygem-foreman_maintain-0.6.10-1.el7sat.noarch

Test steps:
- Have some *-{vmlinuz,initrd.img} files in /var/lib/tftpboot/boot/ directory 
which are older than token_duration settings.
- Run "foreman-maintain health check --label check-tftp-storage"

Observation:
- check-tftp-storage check deletes files older than token_duration time, 
matching *-{vmlinuz,initrd.img} pattern from /var/lib/tftpboot/boot/ directory.
