mkcephfs問題

0.82之後，就沒有mkcephfs命令了

方法一：需要編譯安裝0.80.1,在0.80.1的src下面執行mkcephfs

方法二：如果只是拷貝之前mkcephfs到/sbin下面，執行mkcephfs，則會輸出/usr/local/bin/ceph-osd:error while loading shared libraries: libtcmalloc.so.4: cannot open sharedobject file: No such file or directory

解決方式：

echo /usr/local/lib> /etc/ld.so.conf.d/libtcmalloc.conf

ldconfig

service ceph啟動問題

1、service ceph提示說沒有

進入0.87的src，執行cp –rdpf init-ceph/etc/init.d/ceph

2、如果執行service ceph 提示：The service command supports only basic LSB actions (start, stop, restart,try-restart, reload, force-reload, status). For other actions, please try touse systemctl.

解決方式：新建/lib/lsb，從別的節點拷貝/lib/lsb/init-functions到/lib/lsb/即可

3、如果執行service ceph 啟動時提示/etc/init.d/ceph: line 490:ceph-disk: command not found

執行cp -rfdp/usr/local/sbin/ceph-* /sbin/

ceph -s

啟動後ceph -s提示找不到rados

解決方式：

[[email protected] ~]# cp -rfdp/usr/local/lib/python2.7/site-packages/* /usr/lib64/python2.7/

ceph-fuse掛載

掛載不成功現象：被卡住，無法進行

ceph-fuse -c /root/ceph.conf/mnt/ceph

2014-11-10 14:03:39.108960 7f287b161780 -1ceph-fuse[26142]: starting ceph client

init, newargv = 0x4455750 newargc=11

解決方式：

rados df應該有3個池子。所以手動建立metadata和data

ceph osd pool create metadata 256 256

pool 'metadata' created

cephosd pool create data 256 256

pool 'data' created

cephfs new filesystemNew metadata data

new fs with metadata pool 1 and data pool 2

即可正常掛載

掛載成功後，mdsmap出現

附錄：ceph.conf

{//begin

[global]

# authcluster required = cephx

# authservice required = cephx

# authclient required = cephx

auth supported = none

#      osd crush chooseleaf type = 0

osd pool default size = 1

#      mon data =/home/inspur/data/skdkjzz/$name    

mon data = /data/$name

[mon.a]

host = skdkjzz-inspur

mon addr = 100.2.1.56:6789

[mds.a]

host = skdkjzz-inspur

[osd]

#osddata = /home/inspur/data/skdkjzz/$name

osd data = /data/$name

osd crush update on start = 0

osd mkfs type = xfs

osd mkfs options xfs = -f

osd mount options xfs =rw,noatime

[osd.0]

host = skdkjzz-inspur

devs = /dev/vg_ceph/lv_osd1

osd journal = /dev/vg_ceph/lv_jour1

[osd.1]

host = skdkjzz-inspur

devs = /dev/vg_ceph/lv_osd2

osd journal = /dev/vg_ceph/lv_jour2

}//end
