# repoquery -i ceph
Name : ceph

Release : 1.el6
Architecture: x86_64
Size : 26734691
Packager : Fedora Project

Repository : epel
Summary : User space components of the Ceph file system
Source : ceph-0.56.3-1.el6.src.rpm
Description :
Ceph is a distributed network file system designed to provide excellent
performance, reliability, and scalability.
从命令行手动安装工作正常：
# ceph-fuse /mnt/ceph/
ceph-fuse[28617]: starting ceph client
ceph-fuse[28617]: starting fuse
# df -h
Filesystem Size Used Avail Use% Mounted on
ceph-fuse 72T 2.9T 70T 4% /mnt/ceph
但我想在启动时自动执行此操作。Google 向我指出这页。
/usr/sbin/mount.fuse.ceph
#!/bin/sh
#
# Helper to mount ceph-fuse from /etc/fstab. To use, add an entry
# like:
#
# # DEVICE PATH TYPE OPTIONS
# id=admin /mnt/ceph fuse.ceph defaults 0 0
# id=myuser,conf=/etc/ceph/foo.conf /mnt/ceph2 fuse.ceph defaults 0 0
#
# where the device field is a comma-separated list of options to pass on
# the command line. The examples above, for example, specify that
# ceph-fuse will authenticated as client.admin and client.myuser
# (respectively), and the second example also sets the 'conf' option to
# '/etc/ceph/foo.conf' via the ceph-fuse command line. Any valid
# ceph-fuse can be passed in this way.
set -e
# convert device string to options
cephargs='--'`echo $1 | sed 's/,/ --/g'`
# strip out 'noauto' option; libfuse doesn't like it
opts=`echo $4 | sed 's/,noauto//' | sed 's/noauto,//'`
# go
exec ceph-fuse $cephargs $2 $3 $opts
因此我尝试添加以下内容/etc/fstab：
id=admin,conf=/etc/ceph/ceph.conf /mnt/ceph fuse.ceph defaults 0 0
但mount -a给我：
# mount -a
unrecognized command
因为据我了解，实际上，上述条目将按如下方式运行：
# mount -t fuse.ceph id=admin,conf=/etc/ceph/ceph.conf /mnt/ceph/
unrecognized command
我做错什么了吗？
答案1
我认为正确的语法应该是：
/usr/sbin/mount.fuse.ceph# /mnt/ceph fuse defaults 0 0
那么它将被运行为：
# mount -t fuse /usr/sbin/mount.fuse.ceph# /mnt/ceph/
ceph-fuse[14811]: starting ceph client
ceph-fuse[14811]: starting fuse
验证挂载点是否已启动并正在运行：
# df /mnt/ceph/
Filesystem 1K-blocks Used Available Use% Mounted on
ceph-fuse 77189145600 3011411968 74177733632 4% /mnt/ceph

哦，好像这个版本和那个版本有些不同EPEL 仓库以及来自官方仓库：

/etc/fstab：
conf=/etc/ceph/ceph.conf /mnt/ceph fuse.ceph defaults 0 0
并且fuse.ceph可以指定为文件系统类型：
# mount -t fuse.ceph conf=/etc/ceph/ceph.conf /mnt/ceph/
ceph-fuse[17665]: starting ceph client
ceph-fuse[17665]: starting fuse

我想我找到了这个问题的根本原因。
来自安装手册页：
NOTES
The syntax of external mount helpers is:
/sbin/mount.<suffix> spec dir [-sfnv] [-o options] [-t type.subtype]
where the <type> is filesystem type and -sfnvo options have same meaning like
standard mount options. The -t option is used for filesystems with subtypes
support (for example /sbin/mount.fuse -t fuse.sshfs).
因此，如果您将类型设置为fuse.ceph，它将使用通常的参数运行，并且如果您从 EPEL repo/sbin/mount.fuse.ceph安装，则此辅助程序不存在：ceph
# rpm -ql ceph-fuse
/usr/bin/ceph-fuse
/usr/sbin/mount.fuse.ceph
/usr/share/doc/ceph-fuse-0.56.3
/usr/share/doc/ceph-fuse-0.56.3/COPYING
/usr/share/man/man8/ceph-fuse.8.gz
这就是您收到错误的原因unrecognized command。
快速解决方法是创建一个具有名称/sbin/mount.fuse.ceph和目标的符号链接/usr/sbin/mount.fuse.ceph：
ln -s /usr/sbin/mount.fuse.ceph /sbin/mount.fuse.ceph

在Debian以下适用于 ceph-fuse_0.72.2-1：
/etc/fstab：
mount.fuse.ceph#conf=/etc/ceph/ceph.conf,id=admin /mnt/ceph fuse noatime,allow_other 0 0
