Now the my client machine still can't mount the system, the error
message is "can't read the superblock ".Moreover, I can use
"init-ceph" command to start the system,and the "cosd cmon cmds" is
on process table(so I think the system is running), but I can't use
“ceph” command to administrate the system, “2011-01-13 13:27:05.800552

cs=0 l=0).fault first fault ” is the error message.Do you know what's
wrong may cause these problems? If you have encounteren these
problems, please tell me how to resolve them. Thanks.
I have turned off the iptables, and disabled the firewall.
I install the ceph(0.24) on Fedora 14 ( 2.6.35.6-45 )which runs on
Vmware 6.5.70(for test).Moreover, my mon,mds and osd was on the same
system.
My ceph.conf on mon&mds&osd is:
[global]
; enable secure authentication
;auth supported = cephx
; monitors
; You need at least one. You need at least three if you want to
; tolerate any node failures. Always create an odd number.
[mon]
mon data = /data/mon$id
; logging, for debugging monitor crashes, in order of
; their likelihood of being helpful :)
;debug ms = 1
;debug mon = 20
;debug paxos = 20
;debug auth = 20
[mon0]
host = cephosd
mon addr = 192.168.178.160
; mds
; You need at least one. Define two to get a standby.
[mds]
; where the mds keeps it's secret encryption keys
;keyring = /data/keyring.$name
; mds logging to debug issues.
;debug ms = 1
;debug mds = 20
[mds.alpha]
host = cephosd
; osd
; You need at least one. Two if you want data to be replicated.
; Define as many as you like.
[osd]
sudo = true
; This is where the btrfs volume will be mounted.
osd data =/mnt/btrfs/osd0$id
; Ideally, make this a separate disk or partition. A few
; hundred MB should be enough; more if you have fast or many
; disks. You can use a file under the osd data dir if need be
; (e.g. /data/osd$id/journal), but it will be slower than a
; separate disk or partition.
; This is an example of a file-based journal.
osd journal = /mnt/btrfs/osd$id/journal
osd journal size = 1000 ; journal size, in megabytes
; osd logging to debug osd issues, in order of likelihood of being
; helpful
;debug ms = 1
;debug osd = 20
;debug filestore = 20
;debug journal = 20
[osd0]
host = cephosd
; if 'btrfs devs' is not specified, you're responsible for
; setting up the 'osd data' dir. if it is not btrfs, things
; will behave up until you try to recover from a crash (which
; usually fine for basic testing).
btrfs devs = /dev/sda3
osd data = /mnt/btrfs/osd0
; access control
[group everyone]
; you probably want to limit this to a small or a list of
; hosts. clients are fully trusted.
addr = 0.0.0.0/0
On the client side my install commands is :
$git clone git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git
$cd ceph-client
$make menuconfig //I select "Yes" on all of three option about Ceph
$make && make modules && make modules_install && make install && reboot
Thank you!
