Hi,
You could be running out of memory due to the default Bluestore cache
sizes.
How many disks/OSDs in the R730xd versus the R740xd? How much memory in
each server type? How many are HDD versus SSD? Are you running
Bluestore?
OSD's in Luminous, which run Bluestore, allocate memory to use
Hi,
If you are running Ceph Luminous or later, use the Ceph Manager Daemon's
Balancer module. (http://docs.ceph.com/docs/luminous/mgr/balancer/).
Otherwise, tweak the OSD weights (not the OSD CRUSH weights) until you
achieve uniformity. (You should be able to get under 1 STDDEV). I

Safest to just 'osd crush reweight osd.X 0' and let rebalancing finish.
Then 'osd out X' and shutdown/remove osd drive.

Hi,
Yes and no, for the actual data loss. This depends on your crush map.
If you're using the original map (which came with the installation),
then your smallest failure domain will be the host. If you have replica
size and 3 hosts and 5 OSDs per host (15 OSDs total), then loosing the
After installed required dependency 'virtualenv', then this error also
occurs with -j2.
The workaround I found is to include '--without-openldap' when using
'--with-radosgw'.

Hi,
If its the only think in your pool, you could try deleting the pool
instead.
I found that to be faster in my testing; I had created 500TB when I
meant to create 500GB.
Note for the Devs: I would be nice if rbd create/resize would accept
sizes with units (i.e. MB GB TB PB, etc).

Your OSDs are full. The cluster will block, until space is freed up and
both OSDs leave full state.
You have 2 OSDs, so I'm assuming you are running replica size of 2? A
quick (but risky) method might be to reduce your replica down to 1, to
get the cluster unblocked, clean up space, then go
