The recovery has already finished. It resolves itself, but in the
meantime I saw
What is different with the new hosts?
Better / Large Disk?
More ram?
Higher ghz on the CPU's?
Redundant PSU e.t.c
Depending on what is different about the hardware will help pinpoint how
you may be able to make better use of them.

Hi Cephers,
We are managing a cluster where all machines have the same hardware. The
cluster is used only for object storage. We are planning to increase nodes
number. Those new nodes have better hardware than the old ones. If we only
add those nodes as regular nodes to cluster we are not use the

As there is only 1 RBD client in this testing, does it mean the RBD client

Hi,
currently I'm using telegraf + influxdb to monitor.
Note that this bug seem to be only occur on writes, I don't have latency
increase on read.
counters are op_latency , op_w_latency, op_w_process_latency
SELECT non_negative_derivative(first("op_latency.sum"),
Thanks! So we should not evict client? we run into slow request so guess maybe
evict all clients could help. In which case we should or should not use evict?

For your case, it's likely client got evicted by mds.

Hi Yan Zheng,
Our clients are also complaining about operations like 'du' or 'ncdu' being
very slow. Is there any alternative tool for such kind of operation on
CephFS? Thanks!
Best regards,

Thanks for contributing your knowledge to that book, Anthony - really enjoying
it :)
I didn't mean to use the OS SSD for Ceph use - would buy a second SSD per
server for that... I will take a look at SATA SSD prices, hopefully the smaller
ones (>500MB) will be at an acceptable price so that I
Hello,
Our cephfs looks just stuck. If I run some command such like 'makdir', 'touch'
a new file, it just stuck there. Any suggestion about how to debug this issue
will be very appreciated.

When your node went down, you lost 100% of the copies of the objects that
were stored on that node, so the cluster had to re-create a copy of
everything. When the node came back online (and particularly since your

If I want that only a user can put objects, and not download or delete.
I have to apply a secondary statement denying the GetObject. Yet I did
