This article focuses on "ceph configuration log using independent partitioning method", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Next let the editor to take you to learn "ceph configuration log using independent partitioning method" it!

View the location of the current log

Ceph--admin-daemon / var/run/ceph/ceph-osd.0.asok config show | grep osd_journal

The output is as follows:

[root@ceph-gw-209214 ~] # ceph--admin-daemon / var/run/ceph/ceph-osd.0.asok config show | grep osd_journal "osd_journal": "\ / var\ / lib\ / ceph\ / osd\ / ceph-0\ / journal"

Method 1.

When adding osd using ceph-disk

Ceph-disk prepare-- cluster ceph--cluster-uuid f453a207-a05c-475b-971d-91ff6c1f6f48-- fs-type xfs / dev/sdb1 / dev/sdc1

Command explanation: ceph-disk prepare-- cluster cluster name-- cluster-uuid cluster id-- the type data storage location (blue bottom) log location of the osd added by fs-type,

Note that you should fully plan the disks on your server before preparing them

Mode 2.

Modify the configuration file to add

[osd]

Osd journal = / dev/sda2

Osd journal size = 0

Save exit ceph.conf file

Then execute ceph-osd-- mkjournal-I 0

Note: partition should be allocated in advance.

Mode 3.

1. Modify the configuration file

Add the following configuration to / etc/ceph/ceph.conf

[osd]

Osd journal = / var/log/$cluster-$id/journal

2. Replace osd

Set noout and stop osd

Command: ceph osd set noout

/ etc/init.d/ceph stop osd.1 (stop osd)

Manually move the log

Mv / var/lib/ceph/osd/ceph-1/journal / var/log/ceph-1/

Start osd

/ etc/init.d/ceph start osd.1

Ceph osd unset noout

Complete the migration changes of the ceph cluster logs.

At this point, I believe that everyone on the "ceph configuration log using independent partitioning method" have a deeper understanding, might as well to actual operation of it! Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
