Hi,
For a number of application we use, there is a lot of file duplication. This
wastes precious storage space, which I would like to avoid.
When using a local disk, I can use a hard link to let all duplicate files
point to the same inode (use "rdfind", for example).
As there isn't any ded
Hi,
I mount cephfs on my client servers. Some of the servers mount without any
error whereas others don't.
The error:
# ceph-fuse -n client.kvm -m ceph.somedomain.com:6789 /mnt/kvm -r /kvm -d

Hi all,
We've just hit our first OSD replacement on a host created with
`ceph-volume lvm batch` with mixed hdds+ssds.
The hdd /dev/sdq was prepared like this:
# ceph-volume lvm batch /dev/sd[m-r] /dev/sdac --yes
Then /dev/sdq failed and was then zapped like this:
# ceph-volume lvm zap /dev/

We're glad to announce the first release of Nautilus v14.2.0 stable
series. There have been a lot of changes across components from the
previous Ceph releases, and we advise everyone to go through the release
and upgrade notes carefully.
The release also saw commits from over 300 contributors and
Hi All.
I'm trying to get head and tails into where we can stretch our Ceph cluster
into what applications. Parallism works excellent, but baseline throughput
it - perhaps - not what I would expect it to be.

Hi,
Will debian packages be released? I don't see them in the nautilus repo. I
thought that Nautilus was going to be debian-friendly, unlike Mimic.

One thing you can check is the CPU performance (cpu governor in particular).
On such light loads I've seen CPUs sitting in low performance mode (slower
clocks), giving MUCH worse performance results than when tried with heavier
loads. Try "cpupower monitor" on OSD nodes in a loop and observe the

I don't think file locks are to blame. I tired to control for that in my tests;
I was reading with fio from one set of files (multiple fio pids spawned from a
single command) while writing with dd to an entirely different file using a
different shell on the same host. So one CephFS kernel client

I setup an SSD Luminous 12.2.11 cluster and realized after data had been
added that pg_num was not set properly on the default.rgw.buckets.data pool

Hi,ALL
I've deployed mimic(13.2.5) cluster on 3 CentOS 7.6 servers, then configured
iscsi-target and created a LUN, referring to

I have another server which is CentOS 7.4, configured and mounted the LUN I've
just created, referring to

There aren't any Debian packages built for this release because we
haven't updated the infrastructure to build (and test) Debian packages
yet.
