I have a ceph cluster and I will change my journal devices to new SSD's. In some instructions of doing this they refer to a journal file (link to UUID of journal )
In my OSD folder this journal don’t exist. This instructions is renaming the UUID of new device to the old UUID not to break anything. i was planning to use the command ceph-osd --mkjournal and update the ceph. conf accordingly. Do I need to take care of my missing journal symlink, i think it is a symlink ? Why is it there, and how is it used ?. I actually don’t remember the command i used to create the disk but it's some years ago and i doubt i used ceph-disk. I found the following process in this list, that seemed good. But its still not clear to me if i can skip this journal link ? *set noout* *stop the osds* *flush the journal* *replace journal SSDs* recreate journal partitions update ceph.conf to reflect new journal device names *recreate the journal (for the existing osds)* *start the osds* *unset noout*
