Hi,cephers
we only using krbd in ceph.and it works well near two yeas.but now I
face a size problem.
I have 7 nodes with 10 3T osd each.we using ceph 0.67.9 in
ubuntu12.04.I know it is too old,but update is beyond my control.
and now we use 80% size,so we start to delete historic unneeded
data,b
Hi
I relieved to have found a solution to this problem.
The ansible script for generating the key did not pass the key to the following
command line and sent therefore an empty string to this script (see
monitor_secret).
ceph-authtool /var/lib/ceph/tmp/keyring.mon.{{ monitor_name }} --create-k
Hi Christian,
Thanks for your reply, our performance requirement will be like below.
It will be very helpful is your provide the details for below scenario.
As of now 6 TB data usage, in feature size will be 10 TB.
Per ceph client read and write
Read :- kB/s 57726
Write :-
I'm a lurker here and don't know much about ceph, but:
If fdatasync hardly makes a difference, then either it's not being honoured
(which would be a major problem), or there's something else that is a
bottleneck in your test (more likely).
It's not uncommon for a poor choice of block size (bs) to
Hi,
I am contemplating using a NVRAM card for OSD journals in place of SSD drives
in our ceph cluster.
Configuration:
* 4 Ceph servers
* Each server has 24 OSDs (each OSD is a 1TB SAS drive)
* 1 PCIe NVRAM card of 16GB capacity per ceph server
* Both Client &
Hi All,
I saw the previous thread on this related to
http://tracker.ceph.com/issues/15597
and Yehuda's fix script
https://raw.githubusercontent.com/yehudasa/ceph/wip-fix-default-zone/src/fix-zone
Running this seems to have landed me in a weird state.
I can create and get new buckets and objects

Dense nodes often work better for object-focused workloads than block-focused,
the impact of delayed operations is simply speed vs. a tenant VM crashing.

Some say that all replicas must be written; others say that only min_size, 2 by

Hi All,
I am a newbie here. In latest CEPH (ceph-jewel), I am not able to
remove the filesystem, getting error messages.
Is this the right way to destroy the cephfs?
$ ceph fs rm cephfs1 --yes-i-really-mean-it
Error EINVAL: all MDS daemons must be inactive before removing filesystem
Thanks,
Ra
Hi Ravi,
well is the answer not already written in there ?

All,
I have found an issue with ceph OSDs that are on a SAN and Multipathed. It may
not matter that they are multipathed, but that is how our setup is where I
found the issue.
Our setup has an infiniband network which uses SRP to annunciate block devices
on a DDN.
Every LUN can be seen by every
So, which is correct, all replicas must be written or only min_size before ack?
But for me the takeaway is that writes are protected - even if the journal
drive crashes, I am covered.

You should be protected against single component failures, yes, that's the
point of journals.
It's important to ensure that on-disk volatile cache -- these days in the
8-128MB range -- remain turned off, otherwise it usually presents an
opportunity for data loss especially when power drops. Di
