I have tried to create a ceph filesystem in a single host, for testing purposes, with the following conf file
我尝试在单个主机中创建一个ceph文件系统，用于测试目的，使用以下conf文件
[global]
log file = /var/log/ceph/$name.log
pid file = /var/run/ceph/$name.pid
[mon]
mon data = /srv/ceph/mon/$name
[mon.mio]
host = penny
mon addr = 127.0.0.1:6789
[mds]
[mds.mio]
host = penny
[osd]
osd data = /srv/ceph/osd/$name
osd journal = /srv/ceph/osd/$name/journal
osd journal size = 1000 ; journal size, in megabytes
[osd.0]
host = penny
devs = /dev/loop1
/dev/loop1 is formatted with XFS and is actually a file with 500Mbs (although that shouldn't matter much) Everything works pretty much OK, and health shows:
/ dev / loop1使用XFS格式化，实际上是一个500Mbs的文件（虽然这不应该太重要）一切正常，健康显示：
sudo ceph -s
2013-12-12 21:14:44.387240 pg v111: 198 pgs: 198 active+clean; 8730 bytes data, 79237 MB used, 20133 MB / 102 GB avail
2013-12-12 21:14:44.388542 mds e6: 1/1/1 up {0=mio=up:active}
2013-12-12 21:14:44.388605 osd e3: 1 osds: 1 up, 1 in
2013-12-12 21:14:44.388738 log 2013-12-12 21:14:32.739326 osd.0 127.0.0.1:6801/8834 181 : [INF] 2.30 scrub ok
2013-12-12 21:14:44.388922 mon e1: 1 mons at {mio=127.0.0.1:6789/0}
but when I try to mount the filesystem
但是当我尝试挂载文件系统时
sudo mount -t ceph penny:/ /mnt/ceph
mount error 5 = Input/output error
Usual answers point to ceph-mds not running, but it's actually working:
通常的答案指向ceph-mds没有运行，但它实际上正在工作：
root 8771 0.0 0.0 574092 4376 ? Ssl 20:43 0:00 /usr/bin/ceph-mds -i mio -c /etc/ceph/ceph.conf
In fact, I managed to make it work previously using these instructions http://blog.bob.sh/2012/02/basic-ceph-storage-kvm-virtualisation.html verbatim previously, but after I tried again I obtained the same problem. Any idea of what might have failed?
事实上，我之前使用这些说明http://blog.bob.sh/2012/02/basic-ceph-storage-kvm-virtualisation.html逐字地设法使其工作，但在我再次尝试之后我获得了相同的问题。什么可能失败的想法？
Update as indicated by the comment, dmesg shows a problem
更新如评论所示，dmesg显示问题
[ 6715.712211] libceph: mon0 [::1]:6789 connection failed
[ 6725.728230] libceph: mon1 127.0.1.1:6789 connection failed

Try to use 127.0.0.1. It looks like the kernel is resolving the hostname, but 127.0.1.1 is weird, and maybe it isn't responding to IPv6 loopback.
尝试使用127.0.0.1。看起来内核正在解析主机名，但127.0.1.1很奇怪，也许它没有响应IPv6环回。
