Re: The installation: "terminate called after throwing an instance of 'ceph::buffer::end_of_buffer'"

["doki74216@xxxxxxxxx" <doki74216@xxxxxxxxx>]

Hi, Sage

I set an environment of 7 servers which include 3 MONs(host1 host2
host3), 2 MDSs(host4 host5) and 2 OSDes(host6 host7).
My version is 0.25.2 and OS is Fedora 14.
There's a problem when I was installing the Ceph.
When I finished "mkcephfs -c /etc/ceph/ceph.conf --allhosts --mkbtrfs
-k keyring.bin" .
I start the whole Ceph system.
But here is the problem I met:
The system stops running and it shows the error messages as shown below:

=== mds.0 ===
Starting Ceph mds0 on Ceph4...
 ** WARNING: Ceph is still under heavy development, and is only suitable for **
 **          testing and review.  Do not trust it with important data.       **
terminate called after throwing an instance of 'ceph::buffer::end_of_buffer'
 what():  buffer::end_of_buffer
bash: line 1: 24409 Segmentation fault      (core dumped)
/usr/local/bin/cmds -i 0 -c /tmp/ceph.conf.5135
failed: 'ssh Ceph4  /usr/local/bin/cmds -i 0 -c /tmp/ceph.conf.5135 '

The ceph.conf is shown below:

[global]
     pid file = /var/run/ceph/$name.pid
    debug ms =1
    auth supported = cephx

 [mon]
      mon data = /data1/mon$id

      ;debug ms = 1
      ;debug mon = 20
     ;debug paxos = 20
      ;debug auth = 20

      host = host1
      mon addr = 192.168.200.201:6789

       host = host2
       mon addr = 192.168.200.202:6789

      osd data = /mnt/btrfs/osd$id
      osd journal = /opt/osd/osd$id/journal
     ;osd journal = /data/osd$id/journal
       osd journal size = 512
     ;debug ms = 1
      ;debug osd = 20
      ;debug filestore = 20
      ;debug journal = 20

 [osd0]
      host = host6
      btrfs devs = /dev/sdb1

 [osd1]
      host = host6
      btrfs devs = /dev/sdc1

 [osd2]
      host = host6
      btrfs devs = /dev/sdd1

 [osd3]
      host = host7
      btrfs devs = /dev/sdb1

 [osd4]
      host = host7
      btrfs devs = /dev/sdc1

 [osd5]
      host = host7
      btrfs devs = /dev/sdd1


I want to know why  the system cannot run smoothly.
Thank you!!!!!!!!!!!!!!!
