Hi,
MY current version is v0.24.3, I want to upgrade version to v 0.26.
And my Linux OS is Fedora 14.
I want to know my step is correctly or not?
Here is my upgraded steps:
1) We stop the current system (v0.24.3)by "/etc/init.d/ceph -a stop "
2) We start to download the newest version(v0.26) and install it.
3) Then we mkcephfs (by "mkcephfs -c /etc/ceph/ceph.conf --allhosts --mkbtrfs
-k keyring.bin") and start it(by " /etc/init.d/init-ceph -a -c
/etc/ceph/ceph.conf start").
But there's a problem I met when I was started the Ceph.
The system stops running and it shows the error messages as shown below:
=== mds.0 ===
Starting Ceph mds0 on host4...
** 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 host4 /usr/local/bin/cmds -i 0 -c /tmp/ceph.conf.5135 '
PLEASE HELP me to solve this problem!!!!!!!
THANK YOU~~
The second question is when we upgrate the ceph successfully.
Is there any tool to transfer the existing data (which from the old
ceph system) to the newest system?
Because we thought the data in the older version(eg. 0.24.3) is
slightly different from the newer version(eg. 0.26)?
I want to know the data will be still correctly?
=====================================================================================
By the way , here is my ceph.conf :
[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
[mon0]
host = host1
mon addr = 192.168.200.201:6789
[mon1]
host = host2
mon addr = 192.168.200.202:6789
[mon2]
host = host3
mon addr = 192.168.200.203:6789
[mds]
keyring = /etc/ceph/keyring.$name
;debug ms = 1
;debug mds = 20
[mds0]
host = host4
[mds1]
host = host5
[osd]
keyring = /etc/ceph/keyring.$name
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
Thank you very much !!!!!!!!!!!!!!!
