Hello collective wisdom,
Ceph neophyte here, running v13.2.2 (mimic).
Question: what tools are available to monitor IO stats on RBD level? That is,
IOPS, Throughput, IOs inflight and so on?
I'm testing with FIO and want to verify independently the IO load on each RBD
image.

I need to move instance from one Openstack with Ceph to another
different Openstack with Ceph installation. The instance use volume to
boot with another volume attach for data. The instance has 200GB volume
boot and attach with 1TB volume for data.
From what I know, I need to download the

Hi
I used to get warning message claims client faling to respond
to cache pressure. After I switch rockdb and wal data to ssd, the
message seems disappeared.
However it shows again yesterday and the message looks a little
different: *MDS_CLIENT_RECALL_MANY: 1 MDSs have many *

Wido,
I've been looking into this large omap objects problem on a couple of our
clusters today and came across your script during my research.
The script has been running for a few hours now and I'm already over 100,000
'orphaned' objects!
It appears that ever since upgrading to Luminous
If this is really the last copy of important data: consider making a
full raw clone of the disk before running any ceph-objectstore-tool
commands on it and consider getting some professional help if you are
not too familiar with the inner workings of Ceph.
That being said, it's basically just:
Yeah, that may be the way.
Preferably to disable compaction during this procedure though.
To do that please set
bluestore rocksdb options = "disable_auto_compactions=true"
in [osd] section in ceph.conf
Thanks,
Igor

export all the PGs on the OSD with objectstore-tool and important them

'ceph-bluestore-tool repair' checks and repairs BlueStore metadata
consistency not RocksDB one.
It looks like you're observing CRC mismatch during DB compaction which
is probably not triggered during the repair.
Good point is that it looks like Bluestore's metadata are consistent and

The only strange thing is that ceph-bluestore-tool says that repair was
done, no errors are found and all is ok.
I ask myself what really does that tool.

Managed to fix the issue with some googling from the error above.
There is a bug with urllib3 1.24.1 which breaks the module ordered_dict (1)
I rolled back to a working version "pip install urllib3==1.23" and
restarted the mgr service and all is now working.
Thanks,

Yeah had a few OS updates, but not related directly to CEPH.
The full error log after a reboot is :

Thanks. So it worked before the reboot and did not afterwards? What
changed? Did you perform an OS update?
Would it be possible for you to paste the entire mgr log file

I have a feeling this won't be easy to fix or actually fixable:
- Compaction error: Corruption: block checksum mismatch
- submit_transaction error:
I have only that copy, it is a showroom system but someone put a production
vm on it.

Hi,
I have a Centos5 server with kernel version 2.6.18.
Does it support to mount cephfs with ceph-fuse?
Thanks
