.SH DESCRIPTION
|
|
.PP
|
|
The Object Server is a very simple blob storage server that can store, retrieve
|
|
and delete objects stored on local devices. Objects are stored as binary files
|
|
on the filesystem with metadata stored in the file's extended attributes (xattrs).
|
|
This requires that the underlying filesystem choice for object servers support
|
|
xattrs on files. Some filesystems, like ext3, have xattrs turned off by default.
|
|
Each object is stored using a path derived from the object name's hash and the operation's
|
|
timestamp. Last write always wins, and ensures that the latest object version will be
|
|
served. A deletion is also treated as a version of the file (a 0 byte file ending with
|
|
".ts", which stands for tombstone). This ensures that deleted files are replicated
|
|
correctly and older versions don't magically reappear due to failure scenarios.
