restarting one of the daemons (can't remember now if it was one of the OSDs
or MONs) the values reset to a more sane value and the cluster eventually

Hi guys,
I'm having some issues trying to view the logs for a bucket (the
background to this is we're having trouble handling some multipart

Hello list,
When we upload a large multipart upload to RGW and it fails, we want
to abort the upload. On large multipart uploads, with say 1000+ parts,
it will consistently return 500 errors when trying to abort the
upload. If you persist and ignore the 500s it will eventually abort
the upload.

how it recovers and any manual steps required, and report back with the

I'm designing a new production-like Ceph cluster, but I've run into an issue.
I have 4 nodes with 1 disk for OS, 3 disks for OSDs on each node. However, I

My first question is if it is possible to use a remote disk partition

Hi Dan,
I don't know why NBD wouldn't function, but I also don't think it's the
way you should go. Putting the journals on the OSD disks isn't a
terrible option, but you will suffer the expected double write penalty .
If your system disk is an SSD with fast sequential write throughput
It defaults to 1000 and can be set via the rgw_admin utility or the
admin API when via the max-buckets param.

Hi all,
My workload is mostly writes, but when the writes reach a certain
throughput (iops wise not much higher) the read throughput would tank. This
seems to be impacting my VMs' responsiveness overall. Reads would recover
after write throughput drops.
Is there any way to prioritize read over
Hi Simon,
Have you tried using the Deadline scheduler on the Linux nodes? The deadline
scheduler prioritises reads over writes. I believe it tries to service all
reads within 500ms whilst writes can be delayed up to 5s.
I don’t the exact effect Ceph will have over the top of this, but
I am already using deadline scheduler, with the default parameters:
read_expire=500
write_expire=5000
writes_starved=2
front_merges=1
fifo_batch=16
I remember tuning them before, didn't make a great difference.
