Hallo!
Due to severe maintenance which is going to cause a prolonged
shutdown, I need to move my RGW pools to a different cluster (and
geographical site): my problem is with default.rgw.buckets.data pool,
which is now 100 TB.
Moreover, I'd also like to take advantage of the move to convert
You may want to configure your standby-mds's to be "standby-replay" so
the mds that's taking over from the failed one takes less time to take
over. To manage this you add to your ceph.conf something like this:
---snip---
[mds.server1]
mds_standby_replay = true
mds_standby_for_rank = 0
[mds.s
Hallo again, to reply to my own message... I guess the easiest will be
to setup multisite replication.
So now I will fight a bit with this and get back to the list in case of
troubles.
Sorry for the noise...

Did you run the cluster with only a single monitor?

Hi
Could someone please explain / show how to troubleshoot the space usage in Ceph
and how to reclaim the unused space?
I have a small cluster with 40 osds, replica of 2, mainly used as a backend for
cloud stack as well as the S3 gateway. The used space doesn't make any sense to
me, especial

That is a tough one, the ramifications of a custom cluster name are
wild - it touches everything. I am not sure there is a step-by-step
guide

This seems to be an issue that gets brought up repeatedly, but I haven't
seen a definitive answer yet. So, at the risk of repeating a question
that has already been asked:
How do you migrate a cephfs data pool to a new data pool? The obvious
case would be somebody that has set up a replicated
What about adding the new data pool, mounting it and then moving the
files? (read copy because move between data pools does not what you
expect it do)

Are you talking about adding the new data pool to the current
filesystem? Like:
$ ceph fs add_data_pool my_ceph_fs new_ec_pool
I have done that, and now the filesystem shows up as having two data pools:
$ ceph fs ls
name: my_ceph_fs, metadata pool: cephfs_meta, data pools:
[cephfs_data
1.
change data pool for a folder on the file system:
setfattr -n ceph.dir.layout.pool -v fs_data.ec21 foldername
2.
cp /oldlocation /foldername
Remember that you preferably want to use mv, but this leaves (meta) data
on the old pool, that is not what you want when you want to delete that

I'm not sure why the monitor did not mark it down after 600 seconds
(default). The reason it is so long is that you don't want to move data
around unnecessarily if the osd is just being rebooted/restarted. Usually,
you will still have min_size OSDs available for all PGs that will allow IO
to contin
Given that the MDS knows everything, it seems trivial to add a ceph 'mv'
command to do this. I looked at using tiering to try and do the move, but I
don't know how to tell cephfs that the data is now on the new pool instead
of the old pool name. Since we can't take a long enough downtime to move

Afaik is the mv now fast because it is not moving any real data, just
some meta data. Thus a real mv will be slow (only in the case between
different pools) because it copies the data to the new pool and when
successful deletes the old one. This will of course take a lot more
time, but you at

I've got a RADOSGW instance setup, backed by my demonstration Ceph cluster.
I'm using Amazon's S3 SDK, and I've run into an annoying little snag.
My code looks like this:
amazonS3 = builder.build();
ListObjectsV2Request req = new
ListObjectsV2Request().withBucketName("WorkOrder").withMax
Hi Dominic,
The reason is likely that RGW doesn't yet support ListObjectsV2.
Support is nearly here though: https://github.com/ceph/ceph/pull/28102

Yes, 'mv' on the client is just a metadata operation and not what I'm
talking about. The idea is to bring the old pool in as a cache layer, then
bring the new pool in as a lower layer, then flush/evict the data from the
cache and Ceph will move the data to the new pool, but still be able to
access

Yep, that would certainly explain it.
My apologies, I almost searched for that information before sending the email.

FYI, this PR just merged. I would expect to see backports at least as
far as N, and others would be possible.

The thing i've seen a lot is where an OSD would get marked down because of
a failed drive, then then it would add itself right back again

Afaik MDS doesn't delete the objects immediately but defer it for later. If
you check that again now, how many objects does it report?

This was after a while (I did notice that the number of objects went
higher before it went lower). It is actually reporting more objects now.
I'm not sure if some co-worker or program is writing to the
filesystem... It got to these numbers and hasn't changed for the past
couple hours.

Ok, actually, the problem was somebody writing to the filesystem. So I
moved their files and got to 0 objects. But then I tried to remove the
original data pool and got an error:

Error EINVAL: cannot remove default data pool

Hi,cephers
recently I found auth error logs in most of my osds but not all,
escape some nodes I rebooted after the installation.
it looks like this osd verify to 10.108.87.250:0 first and then the
correct mon.a.
10.108.87.250 now is my radosgw node, maybe I use it as mon in my
first installation
