linux rbd 設(shè)備 底層刪除了，上層怎么刪除

yum remove abc 但是注意了，yum刪掉會(huì)把很多附帶的都刪掉，比如絕對(duì)不能remove python這樣的東西，還有g(shù)cc。這些都是系統(tǒng)的底層，你不要可以不用，或者停掉，一般很少去刪依賴特別多的服務(wù)

相城ssl適用于網(wǎng)站、小程序/APP、API接口等需要進(jìn)行數(shù)據(jù)傳輸應(yīng)用場(chǎng)景，ssl證書未來市場(chǎng)廣闊！成為創(chuàng)新互聯(lián)公司的ssl證書銷售渠道，可以享受市場(chǎng)價(jià)格4-6折優(yōu)惠！如果有意向歡迎電話聯(lián)系或者加微信：028-86922220（備注：SSL證書合作）期待與您的合作！

系統(tǒng)文件里有rbd.exe總是試圖連接外網(wǎng)，這是什么程序，

運(yùn)行Chkdsk工具

Windows7系統(tǒng)運(yùn)行chkdsk工具的步驟

1、左鍵點(diǎn)擊開始 - 運(yùn)行2、在打開的運(yùn)行窗口，我們輸入：CMD，再點(diǎn)擊：確定3、在管理員窗口，我們先復(fù)制chkdsk C: /f /r，再點(diǎn)擊管理員左邊的小方框，在下拉菜單中點(diǎn)擊：編輯 - 粘貼，回車、管理員命令窗口出現(xiàn)：由于該卷正被另一進(jìn)程使用，無法運(yùn)行chkdsk。是否計(jì)劃在下一次系統(tǒng)重新啟動(dòng)時(shí)檢查此卷？（Y/N）

在存儲(chǔ)池啟用rbd：

ceph@ceph-deploy:~/ceph-cluster$ ceph osd pool application enable rbd1-data rbd

enabled application 'rbd' on pool 'rbd1-data'

初始化存儲(chǔ)池：

ceph@ceph-deploy:~/ceph-cluster$ rbd pool init -p rbd1-data

創(chuàng)建存儲(chǔ)池映像文件：

映像文件的管理都是rbd命令來執(zhí)行，rbd可對(duì)映像執(zhí)行創(chuàng)建，查看，刪除，以及創(chuàng)建快照，克隆映像，刪除快照，查看快照，快照回滾等管理操作

ceph@ceph-deploy:~/ceph-cluster$ rbd create data-img1 --size 3G --pool rbd1-data --image-format 2 --image-feature layering

ceph@ceph-deploy:~/ceph-cluster$ rbd create data-img2 --size 5G --pool rbd1-data --image-format 2 --image-feature layering

RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable rbd1-data/data-img1 object-map fast-diff".

In some cases useful info is found in syslog - try "dmesg | tail".

如果鏡像空間不夠用了，我們可以做鏡像空間的拉伸，一般不建議減小

查看rdb1-data存儲(chǔ)池的鏡像

[root@ceph-client1 ~]# rbd ls -p rbd1-data -l

data-img1? 3 GiB? ? ? ? ? ? 2? ? ? ? ? ?

data-img2? 5 GiB? ? ? ? ? ? 2?

比如data-img2空間不夠了，需要拉伸，將data-img2擴(kuò)展到8G

[root@ceph-client1 ~]# rbd resize --pool rbd1-data --image data-img2 --size? 8G

Resizing image: 100% complete...done.

可以通過fdisk -l查看鏡像空間大小，但是通過df -h就看不到
