Re: PGs issue

[Bogdan SOLGA <bogdan.solga@xxxxxxxxx>]

Thank you for your suggestion, Nick! I have re-weighted the OSDs and the status has changed to '256 active+clean'.

Is this information clearly stated in the documentation, and I have missed it? In case it isn't - I think it would be recommended to add it, as the issue might be encountered by other users, as well.

Kind regards,

Bogdan

I see the Problem, as your OSD's are only 8GB they have a zero weight, I think the minimum size you can get away with is 10GB in Ceph as the size is measured in TB and only has 2 decimal places.

For a work around try running :-

ceph osd crush reweight osd.X 1

for each osd, this will reweight the OSD's. Assuming this is a test cluster and you won't be adding any larger OSD's in the future this shouldn't cause any problems.
