Hi guys,

I am trying to create a cluster with ceph, but when I create a monitor with,
pveceph createmon it hangs, and I start receiving the message
failed: 'ulimit -n 32768; /usr/bin/ceph-mon -i 0 --pid-file /var/run/ceph/mon.0.pid -c /etc/pve/ceph.conf --cluster ceph ', I have alfready altered the number of processes files and opened files to everyone:
* soft nofile 50000
* hard nofile 50000
root soft nofile 50000
root hard nofile 50000
* soft nproc 50000
* hard nproc 50000


On /etc/security/limits.conf and also rebooted the machine.

Any hint o what's going on
Thanks in advance.

Hi,
I guess the second part failed and not the first?!
Does an simple
Code: 
ulimit -n 32768
work?

No, It does not work.

Sorry I forgot to mention that, If I run from the cli I got the error:

# ulimit -n 32768; /usr/bin/ceph-mon -i 0 --pid-file /var/run/ceph/mon.0.pid -c /etc/pve/ceph.conf --cluster ceph
error: monitor data filesystem reached concerning levels of available storage space (available: 2% 48868 kB)
you may adjust 'mon data avail crit' to a lower value to make this go away (default: 5%)

How I can adjust this settings ???

Thanks.

Code: 
df -h

Hi,

ulimit -n did not work, the problem was exactly the space on the root partition
so I needed to reinstall all servers with better partitioning.

But just for the case is there a way that I can overcome the space situation??

Thanks.
