Documentation #4568
FAQ entry for changing journal size/moving journal
0%
Description
It's easy if you know how: prevent the cluster from rebalancing on missing
OSD with 'noout', stop the OSD, flush his journal to the filestore, change the journal config,
initialize the new journal, restart the OSD and reset 'noout':
ceph osd set noout
<stop osd.N...perhaps service ceph stop osd.N>
ceph-osd -i N --flush-journal
<reconfigure, resize>
ceph-osd -i N --mkjournal
<restart osd.N>
ceph osd unset noout

This bug has been judged too old to fix. This is because either it is either 1) raised against a version of Ceph prior to Luminous, or 2) just really old, and untouched for so long that it is unlikely nowadays to represent a live documentation concern.
If you think that the closing of this bug is an error, raise another bug of a similar kind. If you think that the matter requires urgent attention, please let Zac Dover know at zac.dover@gmail.com.
