==============
Object Auditor
==============
On system failures, the XFS file system can sometimes truncate files it is
trying to write and produce zero-byte files. The object-auditor will catch
these problems but in the case of a system crash it is advisable to run
an extra, less rate limited sweep, to check for these specific files.
You can run this command as follows::
swift-object-auditor /path/to/object-server/config/file.conf once -z 1000
.. note::
"-z" means to only check for zero-byte files at 1000 files per second.
It is useful to run the object auditor on a specific device or set of devices.
You can run the object-auditor once as follows::
swift-object-auditor /path/to/object-server/config/file.conf once /
--devices=sda,sdb
.. note::
This will run the object auditor on only the sda and sdb devices.
This parameter accepts a comma separated list of values.
