当在glusterfs中将服务器加到存储池中，及运行&gluster peer probe server&命令，
遇到peer probe: failed: Probe returned with unknown errno 107错误时，可以从以下几个方面解决问题
1、查看目标服务器上的防火墙是否关闭
2、查看glusterd在两台机器上都启动并运行
3、检查两台服务器能否ping的通failed to connect captureipagent please restart probe什么意思_百度知道&&&&&&& 最近在Zynq板上启动linaro桌面系统时，发现一个奇怪的问题，系统在启动到最后，已经打印了如下信息：[drm] Initialized axi_hdmi_drm 1.0.0
on minor 0，按理说后面就该是登录系统并显示shell提示符了，但后面显示：VFS: Cannot open root device &mmcblk0p2& or unknown-block(179,2): error -30，即打不开SD卡的第二个分区，之前使用这张卡可正常启动的，而且没有做任何改动。于是我们重新制作桌面文件系统，结果问题依旧。很不解？！下面是启动信息：

&&&&&&& 今天终于发现了问题的所在，原来是SD卡在使用过程中不小心被锁定了，SD卡处于写保护状态，将SD卡解锁，上面的问题就解决了。而且还发现，SD卡处于写保护状态时，如果直接使用笔记本自带的读卡器访问SD卡，则不可写入；但是如果使用USB接口的读卡器，则可以正常读写SD卡，而我们一直使用的是USB接口的SD卡读卡器，所以之前没有发现这个问题。

零碎札记（4）
今天拿了两台旧机器（PentiumD）想搭一个分布式文件系统来玩玩，看看和HDFS对比有哪些使用上的不同。
安装应该是很容易：操作系统Fedora17
32位，留了大片的磁盘空间不做分区（51GBout
of 73GB）。
然后用yum安装；
然后发现需要将glusterd 这个daemon启动……
好了，到了peer
probe。几个钟都卡在unknown
error 107上。
[root@gluster0 sbin]# ./gluster peer probe gluster1
Probe unsuccessful
Probe returned with unknown errno 107
* 两台机器分别在/etc/hosts上命名为 gluster0和&gluster1
查了netstat，端口24007已经打开。没有理由的。没有用DNS但已经都在/etc/hosts文件上做了登记……

跟了一下，发现奇怪问题：entry这个局部指针变量是在哪里赋值？
entry为NULL，第一次的list_for_each_entry() 循环，可是一次都没有进去。
ret = getaddrinfo (hoststr, NULL, NULL, &addr);
entry就莫名其妙有了值，但这个值是有问题的。
猜测，可能漏了为entry赋值，而entry应该赋值为传入的peerinfo变量的头元素；有无内存溢出？
为了验证猜测，看看这个循环的原型：
google了一下：
http://lxr./source/include/linux/list.h#L418
* list_for_each_entry
iterate over list of given type
the type * to use as a loop cursor.
the head for your list.
* @member:
the name of the list_struct within the struct.
#define list_for_each_entry(pos, head, member)
for (pos = list_entry((head)-&next, typeof(*pos), member);
&pos-&member != (head);
pos = list_entry(pos-&member.next, typeof(*pos), member))
原来只是一个宏定义，本质是对成员做一个for循环。

把Windows Installer服务启动下，重启再打开，有可能会好。

1、把Windows Installer服务启动下，再重启可能会好。
2、用安装包（不要在“卸载或更改程序”）卸载这个软件，重新安装以便。另外，Microsoft.NET_Framework_v4.0那个插件也要装上。
3、您用的是cat3还是cat4测试，两者在设备类型设置时略微有些不同。
