Add new features to swift-drive-audit This patch adds two new features to swift-drive-audit. The first is an option in the drive-audit.conf file that allows the operator to prevent the drives ever being unmounted automatically, regardless of the amount of errors present. This could be of benefit in very small systems consisting of only one or two drives where the operator would like to manually unmount/fix the particular drive(s) and minimise any potential downtime. The second is another option in drive-audit.conf that allows the operator to select a recon directory. This directory will then have a drive.recon file which will keep an up-to-date record of the swift drives and any errors associated with them. An example of the output would be as follows: {"/srv/node/disk2": "0", "/srv/node/disk3": "25", "/srv/node/disk0": "0", "/srv/node/disk1": "0", "/srv/node/disk10": "0", "/srv/node/disk7": "0", "/srv/node/disk4": "137", "/srv/node/disk5": "0", "/srv/node/disk8": "0", "/srv/node/disk9": "0", "/srv/node/disk6": "0", "/srv/node/disk11": "60"} This would allow the operator to monitor the errors on the swift drives without having to spend time searching through logs. Also, if this is accepted, it should be possible to add an option to swift-recon that would keep track of this at a system level. Change-Id: Ib5dacf8622b7363e070c274c7c30c8ead448a055

Swift configuration parameter audit This change is the result of an audit through the config parameters provided by swift and how/if they are addressed in the swift documentation. The documentation being the sample config files in the /etc directory or the documentation. This change is only concerned with the config files in etc/ next I will look at the documentation in the doc/ folder. This change makes the following assumptions: - Unless stated otherwise, the commented out parameter in the sample configuration is the default for swift. - When the default in the code differs from that of the sample configuration, the default in the code is correct. Container reconciler: Parameter: interval - code: 30 - config: 300 Result: config = 30 Object Expirer: Parameter: recon_cache_path - code: /var/cache/swift - config: Parameter missing Result: Add parameter swift-dispersion-populate && swift-dispersion-report Parameter: auth_version - code: 1.0 - config: 2.0 (due to being a confusing example of how to setup version 2.0). Result: Added 'auth_version = 1.0' to the right section (showing default and make the sample configuration for auth version 2.0 easier to understand. swift-drive-audit: Parameter: log_file_pattern - code: /var/log/kern.*[!.][!g][!z] - config: /var/log/kern* Result: config = /var/log/kern.*[!.][!g][!z] NOTE: swift-drive-audit uses a parameter called device_dir which defaults to '/srv/node'. In all other swift binaries/services there is a similar parameter called devices which stores the same thing. This is an inconsistency which I haven't fixed as this could break existing swift clusters out in the wild. Proxy Server: Parameter: object_chunk_size - code: 65536 - config: 8192 Result: config = 65536 Parameter: client_chunk_size - code: 65536 - config: 8192 Result: config = 65536 Parameter: strict_cors_mode - code: True - config: No parameter Result: config = True Account and Container replicator configuration confusion: NOTES: The account and container replicators have parameters: - interval - run_pause Both of these are loaded into the same variable in code: self.interval = int(conf.get('interval') or conf.get('run_pause') or 30) If a user sets both to different values then interval is used. Result: Update the configuration to make this more clear. DocImpact Change-Id: Iaadbb1a6284f8b3e0801bc343b29772f70f4bf6e
