Hi,
for testing I would like to create some OSD in the hammer release with
journal size 0
I included this in ceph.conf:
[osd]
osd journal size = 0
Then I zapped the disk in question and tried:
'ceph-deploy disk zap o1:sda'
Thank you for your advice how to prepare an osd without journal /
journal size 0.
Thanks and regards,
Mike
