My vm kernel version is "Linux ubuntu12 3.2.0-23-generic".
"ceph-s" shows
" health HEALTH_OK
monmap e1: 1 mons at {a=10.100.211.146:6789/0}, election epoch 0, quorum 0 a
osdmap e152: 10 osds: 9 up, 9 in
pgmap v48479: 2112 pgs: 2112 active+clean; 23161 MB data, 46323 MB
used, 2451 GB / 2514 GB avail
mdsmap e31: 1/1/1 up {0=a=up:active} "
In my vm, I do operations like:
I install 4 debs on my vm, such as libnss3, libnspr4, librados2,
librbd1. And then execute "modprobe rbd" so that I can map a image to
my vm.
Then "rbd create foo --size 10240 -m $monIP(my ceph mon IP)",
"rbd map foo -m $monIP" ------ Here a device /dev/rbd0 can be
used as a local device
"mkfs -t ext4 /dev/rbd0"
"mount /dev/rbd0 /mnt(or some other directory)"
After the operations above, I can use this device. But it oftern
prompt some log like "libceph: osd9 10.100.211.68:6809 socket closed".
I just want to mount a device to my vm, so I didn't install a ceph
client. Is this proper to do so?
Thank you for youer answer!
