We’re using Nexus 3.6.2. We have a Maven repository group that contains four separate Maven repos. Each of these Maven repos has its own blob store. The Maven group also has its own blob store, required for reasons that aren’t entirely clear (it was asked, but not definitively answered, here. A
Nexus reports the size of the Maven group’s blobstore as 1.7gb, which might make sense if it’s storing some metadata. Checking the disk usage on the physical box though and it’s 109gb (over x60 the difference). That’s very significant and I can’t understand why a blobstore for a repository group would be that large in any case. The only unusual thing I can see is that this blob store - which I thought would rarely be used - has over 100x more blobs than the blob store used by repos that are in active use (such as our -snapshots repo).
What’s going on here? Why the difference? I’d like to be able to claim back a good chunk of this 100gb.
