The syntax for the rados bench is as follows:
# rados bench -p <pool_name> <seconds> <write|seq|rand> -b <block size> -t --no-cleanup
The syntax can be explained as follows:
- -p: -p or --pool specifies the pool name.
- <seconds>: Tests the time in seconds.
- <write|seq|rand>: Is the type of test, for example, write, sequential read, or random read.

- -t: Is the number of concurrent threads; the default is 16.
- --no-cleanup: Is the temporary data that is written to the pool by the rados bench that should not be cleaned. This data will be used for read operations when they are used with sequential reads or random reads. The default is cleaned up.
