要解决Artifactory的文件系统使用量远大于总存储库大小的问题，可以考虑以下解决方法：

1. 清理不再使用的存储库：首先，可以检查Artifactory中的存储库，并删除不再使用的存储库。可以使用Artifactory的REST API来列出和删除存储库。

import requests

# 列出存储库
def list_repositories():
    url = "http://artifactory_url/api/repositories"
    response = requests.get(url)
    repositories = response.json()
    return repositories

# 删除存储库
def delete_repository(repo_key):
    url = f"http://artifactory_url/api/repositories/{repo_key}"
    response = requests.delete(url)
    if response.status_code == 204:
        print(f"Repository {repo_key} deleted successfully.")
    else:
        print(f"Failed to delete repository {repo_key}.")

# 列出存储库并删除不再使用的存储库
repositories = list_repositories()
for repo in repositories:
    repo_key = repo["key"]
    delete_repository(repo_key)

2. 清理旧的构建和快照版本：Artifactory中的构建和快照版本可能会占用大量空间。可以使用Artifactory的REST API来列出并删除旧的构建和快照版本。

import requests

# 列出构建
def list_builds():
    url = "http://artifactory_url/api/build"
    response = requests.get(url)
    builds = response.json()
    return builds

# 删除构建
def delete_build(build_name, build_number):
    url = f"http://artifactory_url/api/build/{build_name}/{build_number}"
    response = requests.delete(url)
    if response.status_code == 200:
        print(f"Build {build_name}/{build_number} deleted successfully.")
    else:
        print(f"Failed to delete build {build_name}/{build_number}.")

# 列出构建并删除旧的构建
builds = list_builds()
for build in builds:
    build_name = build["name"]
    build_number = build["number"]
    delete_build(build_name, build_number)

3. 压缩存储库：Artifactory支持存储库的压缩功能，可以减少文件系统的使用量。可以使用Artifactory的REST API来触发存储库的压缩。

import requests

# 触发存储库的压缩
def compress_repository(repo_key):
    url = f"http://artifactory_url/api/repositories/{repo_key}/compress"
    response = requests.post(url)
    if response.status_code == 200:
        print(f"Repository {repo_key} compressed successfully.")
    else:
        print(f"Failed to compress repository {repo_key}.")

# 触发存储库的压缩
repositories = list_repositories()
for repo in repositories:
    repo_key = repo["key"]
    compress_repository(repo_key)

请注意，在上述代码示例中，需要将artifactory_url替换为实际的Artifactory URL。此外，还需要根据实际情况进行适当的身份验证和错误处理。
