This article will explain in detail how to optimize the configuration parameters of ceph for everyone. Xiaobian thinks it is quite practical, so share it with you for reference. I hope you can gain something after reading this article.

There are many configurable parameters in the ceph configuration file/etc/ceph.conf, which can be viewed by the following command:

root@osd2:/var/run/ceph# ceph --admin-daemon ceph-mon.osd2.asok config show|wc -l759

Some parameters have been modified to optimize performance. Based on a previous article and other sources, summarize the configurations that can be optimized.

1. keep FD

filestore_fd_cache_size = 204800filestore_omap_header_cache_size = 204800

2. sparse read/write

filestore_fiemap = true

3. drop default limits

#Implicit values "filestore_wbthrottle_xfs_bytes_start_flusher": "41943040","filestore_wbthrottle_xfs_bytes_hard_limit": "419430400","filestore_wbthrottle_xfs_ios_start_flusher": "500","filestore_wbthrottle_xfs_ios_hard_limit": "5000","filestore_wbthrottle_xfs_inodes_start_flusher": "500","filestore_wbthrottle_xfs_inodes_hard_limit":"5000",#corrected filestore_wbthrottle_xfs_bytes_start_flusher = 5000000filestore_wbthrottle_xfs_indoes_start_flusher = 500filestore_wbthrottle_xfs_indoes_hard_limit = 50000filestore_wbthrottle_xfs_ios_start_flusher = 50000filestore_wbthrottle_xfs_bytes_hard_limit = 500000filestore_wbthrottle_xfs_ios_hard_limit = 500000#default value "filestore_queue_max_ops":"50","filestore_queue_max_bytes": "104857600","filestore_queue_committing_max_ops": "500","filestore_queue_committing_max_bytes": "104857600",#correction value filestore_queue_max_ops = 5000filestore_queue_max_bytes = 10240000filestore_queue_committing_max_ops = 50000#default value "journal_queue_max_ops":"300","journal_queue_max_bytes": "33554432",#correction value journal_queue_max_ops = 50000journal_queue_max_bytes = 102400000

4. use rbd cache

rbd cache = true

5. speed cache

filestore_fd_cache_random = true

6. async messenger

ms_type = async(no)ms_async_op_threads = 5(no)ms_dispatch_throttle_bytes = 104857600000

7. op thread

osd op threads = 4osd disk threads = 2filestore op threads = 4
