Thanks John, that works! Also works with multiple commands, e.g I granted my
user access to both `ceph fs status` and `ceph status`:
mgr 'allow command "fs status", allow command "status"'

Hi John,
I am running ceph Luminous 12.2.1 release on the storage nodes with v4.4.114
kernel on the cephfs clients.
3 client nodes are running 3 instances of a test program.
The test program is doing this repeatedly in a loop:
* sequentially write a 256GB file on cephfs
* delete the
I have had this happen during large data movements. Stopped happening after
I went to 10Gb though(from 1Gb). What I had done is injected a setting (
and adjusted the configs ) to give more time before an OSD was marked down.

Thanks David and John,
That sounds logical now. When I did read "To make a snapshot on
directory “/1/2/3/”, the client invokes “mkdir” on “/1/2/3/.snap”
directory (http://docs.ceph.com/docs/master/dev/cephfs-snapshots/)" it
didn't come to mind I should create subdirectory immediately.
Hi,
is it possible to establish RBD mirroring between replicated and erasure
coded pools?
I'm trying to setup replication as described on
http://docs.ceph.com/docs/master/rbd/rbd-mirroring/ without success.

Hello Eugen
Yes all of the clients use the same credentials for authentication. Ive
mounted the cephFS on about 10 VMs and it works only on about 4 of them.
We have used this setup before but on Ubuntu 14.04 with ceph 0.94.1,
ceph-deploy 1.5.35 and ceph-fuse 0.80.11.
In dmesg there is
Hi all,
I updated an existing Luminous cluster to Mimic 13.2.1. All daemons were
updated, so I did ceph osd require-osd-release mimic, so everything
seems up to date.
I want to try the snapshots in Mimic, since this should be stable, so i ran:
[root@osd2801 alleee]# ceph fs set cephfs
The pool deletion might have triggered a lot of IO operations on the disks
and the process might be too busy to respond to hearbeats, so the mons mark
them as down due to no response.
Check also the OSD logs to see if they are actually crashing and
restarting, and disk IO usage (i.e. iostat).
Hi,
Some of the ceph-fuse clients hang on write operations to the cephFS.
Do all the clients use the same credentials for authentication? Have
you tried to mount the filesystem with the same credentials as your
VMs do and then tried to create files? Has it worked before or is this
a new
Hello,
we have a Ceph Cluster 10.2.10 on VMs with Ubuntu 16.04 using Xen as the
hypervisor. We use CephFS and the clients use ceph-fuse to access the files.
Some of the ceph-fuse clients hang on write operations to the cephFS. On
copying a file to the cephFS, the file is created but it's

hi,
found the issue:
problem was a wrong syntax from Telegraf, which does not create the
socket and because there was no socket, I've got the "no such file ..."
I tried later udp/tcp ... but I didn't read it correctly, that Telegraf
creates the necessary input :-D
Now it works :-)

Hi Everyone,
I just upgrade our cluster to Luminous 12.2.7 and I delete a quite large pool
that we had (120 TB).
Our cluster is made of 14 Nodes with each composed of 12 OSDs (1 HDD -> 1 OSD),
we have SDD for journal.
After I deleted the large pool my cluster started to flapping on all OSDs.

I try to get the Telegraf plugin from Mimic on Luminous running (Debian
Stretch). I copied the files from the Git into

Hi all,
The latest hint I received (thanks!) was to replace a failing hardware.
Before that, I updated the BIOS, which included a CPU microcode fix for
melddown/spectre and probably other thngs. Last time I had checked, the
vendor didn't have that fix yet.
Since this update, not CATERR
