stash removing cache

[Paul DeSousa]

my files system for stash is 100% full and I want to remove some of the large files that are cached as caches is taking up the space, what is the best manner to accomplish this?

[Michael Heemskerk · Accepted solution]

You're most likely running into space issues because of the caches under STASH_HOME/cache/scm. These are caches for git operations such as ref advertisement and clone. Especially clones can be fairly large depending on the size of your repositories.

The scm-cache has a 'minimum free space' setting for controlling when it will stop caching. Default is 1Gb but you can configure a higher value in your stash-config.properties You'll need to restart Stash to apply the new configuration.

What do I put in the stash-config.properties file? Also is it possible that we do not have a minimum free space set to on as it filled the partition to 100%, all that is on that partition is stash's home. We almost never have more than a Gig of free space there...

This is the default that Stash uses if you haven't overridden it. # Controls when caching is disabled because there is not enough space available on the file system # Configured value is in BYTES. The default is 1GB plugin.stash-scm-cache.minimum.free.space=1073741824 When there is less than 1GB free Stash won't write to the cache. However, if you have 1.5GB free and then clone a repository that is 1GB you'll end up with 500MB free. Ideally, you'd configure this setting to be a bit higher than the size of your largest repository. If you're not using a CI server for builds or you only have a small number of builds, you can also disable the caching completely by adding this to you stash-config.properties: plugin.stash-scm-cache.upload-pack.enabled=false

Thanks!

The cleanest way of removing the cache is restarting the Stash service. In order to avoid the same problem in the future, set this in your Stash config to the desired value:

#min. disk space left by caching, 32GB
plugin.stash-scm-cache.minimum.free.space=34359738368

(The default value is very small.)

[Paul DeSousa]

That looks fairly large, We do not have a lot of space on that disk. And if there was a default why would it fill up the partition to 100%? Currently we have the home in its own partition which is 6 gig. What should I set the minimum to?

[Balázs Szakmáry]

As Michael said above, the default is 1GB, I think that should be good for you. If the disk got completely full, it was probably not the cache that filled the last 1GB. Check what else is big. For us the log files can accumulate to quite much data, especially when debug logging is on.
