（9）cephpool性能測(cè)試-創(chuàng)新互聯(lián)

Ceph包含在rados bench RADOS存儲(chǔ)集群上執(zhí)行性能基準(zhǔn)測(cè)試的命令。該命令將執(zhí)行寫(xiě)測(cè)試和兩種類(lèi)型的讀測(cè)試。--no-cleanup在測(cè)試讀寫(xiě)性能時(shí)，該選項(xiàng)很重要。默認(rèn)情況下，該rados bench命令將刪除已寫(xiě)入存儲(chǔ)池的對(duì)象。留在這些對(duì)象后面允許兩個(gè)讀取測(cè)試來(lái)測(cè)量順序和隨機(jī)讀取性能。

創(chuàng)新互聯(lián)專(zhuān)業(yè)成都做網(wǎng)站、網(wǎng)站建設(shè)、外貿(mào)營(yíng)銷(xiāo)網(wǎng)站建設(shè)，集網(wǎng)站策劃、網(wǎng)站設(shè)計(jì)、網(wǎng)站制作于一體，網(wǎng)站seo、網(wǎng)站優(yōu)化、網(wǎng)站營(yíng)銷(xiāo)、軟文發(fā)布平臺(tái)等專(zhuān)業(yè)人才根據(jù)搜索規(guī)律編程設(shè)計(jì)，讓網(wǎng)站在運(yùn)行后，在搜索中有好的表現(xiàn)，專(zhuān)業(yè)設(shè)計(jì)制作為您帶來(lái)效益的網(wǎng)站！讓網(wǎng)站建設(shè)為您創(chuàng)造效益。

（2）創(chuàng)建一個(gè)新的存儲(chǔ)池
[root@node141 mnt]# ceph osd pool create rbd 128 128

（3）測(cè)試一下rbd的寫(xiě)性能，添加 --no-cleanup參數(shù)
