Hi, Apologies for this trivial question, but what is the correct procedure to replace a failed OSD that uses a shared journal device? Suppose you have 5 spinning disks (sde,sdf,sdg,sdh,sdi) and these each have a journal partition on sda (sda1-5). Now sde fails and is replaced with a new drive. Where do you put the journal for the new sde? It _should_ be sda1 of course, but I didn?t yet work out the correct way to reuse that. Using ceph-disk (in dumpling), I found that ceph-disk prepare /dev/sde /dev/sda will create a 6th partition on sda. If I rm partition 1 before running ceph-disk, it seems to re-use partition 1 but the udev triggers (probably partx) don?t quite like this and the osd is never activated. I?m just curious, for such a routine operation, what are most admins doing in this case? Cheers, Dan
