Hi, dear cephers,
On one ceph i have a failing disk, whose SMART information signals an impending failure
but still availble for reads and writes. I am setting up a new disk on the same node to
replace it.
What is the best procedure to migrate data (or COPY ) from the failing OSD to the new
one?
Is there any stardard method to copy the OSD from one to another?
best regards,

Destroy this OSD, replace disk, deploy OSD.

For Ceph,this is fortunately not a major issue. Drives failing is
considered entirely normal, and Ceph will automatically rebuild your data
from redundancy onto a new replacement drive.If You're able to predict the
imminent failure of a drive, adding a new drive /OSD will automatically
start flowing data onto that drive immediately, thus reducing the time
period with decreased redundancy.If You're running with very tight levels
of redundancy, You're better off, creating a new OSD on a replacement drive
before destroying the old OSD on the failed drive. But if You're running
with anything near the recommended/default levels of redundancy, it doesn't
really matter in which order you do it.
