-------------
pool
String, giving ID or name. String can only have characters in the set [a-zA-Z0-9\_-.]. Which RADOS pool a file's data objects will be stored in.
This is a string and returns either an ID or a name. Strings may contain
only characters in the set ``[a-zA-Z0-9\_-.]``. This determines the RADOS
pool that stores a file's data objects.
pool_id
String of digits. This is the system assigned pool id for the RADOS pool whenever it is created.
This is a string of digits. This is the pool ID that was assigned by Ceph
at the time of the creation of the RADOS pool.
pool_name
String, given name. This is the user defined name for the RADOS pool whenever user creates it.
This is a string. This is the name of the RADOS pool as defined by the user
when the pool was created.
pool_namespace
String with only characters in the set [a-zA-Z0-9\_-.]. Within the data pool, which RADOS namespace the objects will
be written to. Empty by default (i.e. default namespace).
This is a string containing only characters in the set ``[a-zA-Z0-9\_-.]``.
This determines which RADOS namespace within the data pool that the objects
will be written to.
Empty by default (i.e. default namespace).
stripe_unit
Integer in bytes. The size (in bytes) of a block of data used in the RAID 0 distribution of a file. All stripe units for a file have equal size. The last stripe unit is typically incomplete–i.e. it represents the data at the end of the file as well as unused “space” beyond it up to the end of the fixed stripe unit size.
This is an integer. The size (in bytes) of a block of data used in the
distribution of a file. All stripe units for a file have equal size. The
last stripe unit is typically incomplete–that is, it represents the data at
the end of the file as well as unused “space” beyond the end of the file to
the end of the fixed stripe unit size.
stripe_count
Integer. The number of consecutive stripe units that constitute a RAID 0 “stripe” of file data.
Integer. The number of consecutive stripe units that constitute a RAID 0
“stripe” of file data.
object_size
Integer in bytes. File data is chunked into RADOS objects of this size.
Integer. The size of the object in bytes. File data is chunked into RADOS
objects of this size.
