Hi Christian,
thank you. I found _netdev option by myself. I was a little bit confused
because in the Ceph offical documentation there is no hint that you
should use _netdev.
A last question. I have 3 nodes with 9 OSD:
[root@linsrv001 ~]# ceph osd tree
ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY
-1 0.13129 root default
-2 0.04376 host linsrv002
2 0.01459 osd.2 up 1.00000 1.00000
3 0.01459 osd.3 up 1.00000 1.00000
4 0.01459 osd.4 up 1.00000 1.00000
-3 0.04376 host linsrv003
5 0.01459 osd.5 up 1.00000 1.00000
6 0.01459 osd.6 up 1.00000 1.00000
7 0.01459 osd.7 up 1.00000 1.00000
-4 0.04376 host linsrv001
8 0.01459 osd.8 up 1.00000 1.00000
9 0.01459 osd.9 up 1.00000 1.00000
10 0.01459 osd.10 up 1.00000 1.00000
My pool has configured a replicated size of 3. If I write a file with
1GB. Does it mean the data is on 3 OSDs?
Have a nice sunday.
Regards - Willi

Hello,
I found an issue. I've added a ceph mount to my /etc/fstab. But when I
boot my system it hangs:
libceph: connect 192.168.0.5:6789 error -101
After the system is booted I can successfully run mount -a.
So what does that tell you?
That Ceph can't connect during boot, because... there's no network yet.
This is what the "_netdev" mount option is for.

Hello,
fixed it by myself. The secret was not in Base64. But I have a
question. Should I deploy my clients with ceph-deploy which will give
me a later version of libceph which also supports records
in /etc/hosts?

Hello,
I hope somebody could help. I'm trying to mount cephfs on CentOS 7 in
/etc/fstab.
192.168.0.5:/ /mnt/cephfs ceph
noatime,dirstat,name=admin,secret=mykey 0 0
Which is giving me.
[root@linsrv004 ~]# mount -a
mount: wrong fs type, bad option, bad superblock on 192.168.0.5:/,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
I haven't installed ceph or ceph-common.
The following command works:
mount -t ceph -o name=admin,secret=mykey
192.168.0.5,192.168.0.6,192.168.0.7:/ /mnt/cephfs
Many thanks & Regards,
Willi
