深海游弋的鱼 – 默默的点滴

resize2fs:Memory alloction failed while trying to resize

最近入手一块 12T 的西数红盘，打算安装到 WD MyCloud Gen1 上，从 4TB 版本升级到 12TB 版本，作为 TimeMachine 来用。

使用拯救死翘翘了的WD MyCloud 方式恢复镜像之后，最后一步执行

$ resize2fs /dev/sda4

1	$ resize2fs /dev/sda4

结果报告如下错误：

$ resize2fs /dev/sda4
resize2fs 1.42.5 (29-Jul-2012)
Resizing the filesystem on /dev/sda4 to 2928542715 (4k) blocks.
resize2fs: Memory allocation failed while trying to resize /dev/sda4
Please run 'e2fsck -fy /dev/sda4' to fix the filesystem
after the aborted resize operation.

$ resize2fs /dev/sda4

resize2fs 1.42.5 (29-Jul-2012)

Resizing the filesystem on /dev/sda4 to 2928542715 (4k) blocks.

resize2fs: Memory allocation failed while trying to resize /dev/sda4

Please run 'e2fsck -fy /dev/sda4' to fix the filesystem

after the aborted resize operation.

这个原因网上查询了很久，基本上断定是 e2fsprogs 1.42.5 的 BUG，这个问题在 e2fsprogs 1.42.9 版本修复。修复内容参考代码下的 debian/changelog。

关键日志如下：

e2fsprogs (1.42.9-1) unstable; urgency=low

  * Fixed a large number of bugs in resize2fs, e2fsck, debugfs, to
    handle bigalloc and 64-bit file systems.

e2fsprogs (1.42.9-1) unstable; urgency=low

* Fixed a large number of bugs in resize2fs, e2fsck, debugfs, to

handle bigalloc and 64-bit file systems.

编译过程参考 How to successfully build packages for WD My Cloud from source 中对于 e2fsprogs 1.42.13 的编译。

WD MyCloud编译golang/git-lfs

按照How to successfully build packages for WD My Cloud from source中的介绍，搭建完成WDMyCloud的编译环境

整个 WD MyCloud 的编译项目，可以直接在树莓派中进行编译。只是编译4KB分页（主要用于编译过程）的高版本应用的时候，需要在 raspbian-wheezy 系统中进行编译。

在树莓派中编译 WD MyCloud 代码的时候，由于都是 ARM 环境，因此，不需要 QEMU 的介入，以前由于 QEMU 导致的问题可以规避。

推荐在树莓派4B版本上搭建编译环境，效果来看，速度还是不错的。

这个问题产生的原因是在qemu中创建线程/进程的时候，要求增加CLONE_SYSVSEM标志，否则会出现异常。 go在创建线程/进程的时候，没有指定这个标记。解决方法就是修改src/pkg/runtime/os_linux.c中的void runtime·newosproc(M *mp, void *stk)函数，在flag中增加CLONE_SYSVSEM标志。

这个问题解决起来比较复杂，我们在x86下面直接进行交叉编译的时候，是没办法通过编译的，我们可以通过树莓派下进行编译。树莓派使用2015-05-05-raspbian-wheezy版本的镜像来进行编译。

树莓派这个版本的系统问题在于 wheezy 的源已经被移动地址，因此更新安装软件的时候会报告 404 错误，我们需要手工修改一下源地址。

这个问题产生的原因是在qemu中无法处理编号为 64 的信号(Qemu rejects rt_sigaction of SIGRTMAX (64).)，我们需要忽略这个信号。解决方法就是修改src/pkg/runtime/os_linux.c中的void runtime·setsig(int32 i, GoSighandler *fn, bool restart)函数，忽略这个信号。

# BUG `fatal error: rt_sigaction failure`
$ sed -i "s/runtime·rt_sigaction(i, \&sa, nil, sizeof(sa.sa_mask)) != 0/runtime·rt_sigaction(i, \&sa, nil, sizeof(sa.sa_mask)) != 0 \&\& i != 64/g" src/pkg/runtime/os_linux.c

编译环境安装完成之后，可以成功编译golang-1.3.3，中途可能会失败，失败之后，重新编译可以通过。

编译 golang-1.4 ,由于 golang-1.4 的特殊性，任何高于 golang-1.4 版本的 golang ，都需要 golang-1.4 的编译环境才能开始编译安装！

基于APC BK650-CH UPS连接群晖DS718+通过NUT(Network UPS Tools)实现WDMyCloud Gen1断电自动关机

最近新入手了 群晖 DS718+，鉴于群晖断电容易损坏硬盘的传说，为了保证设备的安全，特别购入了 APC BK650-CH UPS 。

APC BK650-CH UPS 有多个电源插槽，可以同时为多个设备提供断电保护，但是 APC BK650-CH UPS 只有一个 USB 设备接口，这个接口用来提供电源状态信息，比如是否断电，当前电量信息等数据。这就造成收到断电通知的只能有一个设备，这个设备必须通过网络通知其他设备，才能实现全部的断电通知。

软件磁盘阵列(RAID)

RAID软件磁盘阵列

RAID 即廉价磁盘冗余阵列，其高可用性和可靠性适用于大规模环境中，相比正常使用，数据更需要被保护。RAID 是将多个磁盘整合的大磁盘，不仅具有存储功能，同时还有数据保护功能.

软件磁盘整列通过mdadm命令创建.

RAID等级

RAID-0: 等量模式，stripe,性能较佳，磁盘利用率100%
RAID-1: 镜像模式，mirror，安全性较佳，磁盘利用率50%
RAID-0+1：先组成RAID-0，再有RAID-0组成RAID-1 性能安全兼顾，磁盘利用率50%
RAID-1+0：先组成RAID-1，再有RAID-1组成RAID-0 性能安全兼顾，磁盘利用率50%
RAID-5: 等量模式与分布式奇偶校验，性能与安全份均衡，磁盘可用量等于n-1
RAID-6: 等量模式与双分布式奇偶校验，性能与安全均衡，磁盘可用量等于n-2

利用rsync断点续传scp中断的文件传输

服务器经常需要备份，但是长时间的下载，难免会出现下载中断的情况。

一直使用scp下载备份好的文件，以前数据量少的时候，直接重新下载就可以了。随着网站上数据越来越多，下载的时间越来越长，完全重新开始变得不现实了。有时候下载到90%以上的时候，失败了，完全重传是没有必要的。

我们只需要下载缺失的部分就好了，幸运的是rsync支持这种需求。

具体的做法是将如下的选项组合传递给rsync，-checksum（文件分块计算校验和，只传输校验和不一致的部分），-in-place（将文件原地替换，因为rsync通常会写一个临时文件，然后移动）和-no-whole-file（告诉rsync不要复制整个文件，而是使用deltas（部分传输））。

例如：

$ rsync -Pa --checksum --inplace --no-whole-file --progress remote.server:file local.file

1	$ rsync -Pa --checksum --inplace --no-whole-file --progress remote.server:file local.file

下面是一个真实的例子：

$ rsync -Pa --checksum --inplace --no-whole-file --progress -e 'ssh -p 22' user@www.mobibrw.com:~/backup/wordpress.20181203.tar.gz wordpress.20181203.tar.gz

receiving incremental file list
sent 19 bytes  received 76 bytes  0.22 bytes/sec
total size is 8379088896  speedup is 88200935.75

$ rsync -Pa --checksum --inplace --no-whole-file --progress -e 'ssh -p 22' user@www.mobibrw.com:~/backup/wordpress.20181203.tar.gz wordpress.20181203.tar.gz

receiving incremental file list

sent 19 bytes received 76 bytes 0.22 bytes/sec

total size is 8379088896 speedup is 88200935.75

整个过程非常的快，比完全重传快多了。

scp命令拷贝文件非常好用，但在拷贝大文件时存在一个问题就是连接经常会断开，此时再使用scp进行拷贝会重新拷贝文件，为了解决这个问题。我们可以使用rsync命令来进行断点续传。命令如下：

$ rsync -P --rsh=ssh xxx.zip 192.168.0.1:~/

1	$ rsync -P --rsh=ssh xxx.zip 192.168.0.1:~/

为了使用方便可以设置alias:

$ alias rscp="rsync -P --rsh=ssh"

1	$ alias rscp="rsync -P --rsh=ssh"

WD MyCloud编译git-2.19

目前，能编译通过，但是安装的时候，依赖关系不正确，估计还是需要继续调整编译配置文件才行。

1.按照How to successfully build packages for WD My Cloud from source中的介绍，搭建完成WDMyCloud的编译环境2.从高版本Debian源里下载git-2.19的源代码包，然后手工编译，如下：

$ rm -rf debian/git-el.install

# 重新编译
$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

$ rm -rf debian/git.install

$ rm -rf debian/git-el.install

# 重新编译

$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

如果出现如下错误信息：

dh_installdeb: unknown dpkg-maintscript-helper command: dir_to_symlink
make: *** [binary] Error 25
dpkg-buildpackage: error: debian/rules binary gave error exit status 2

dh_installdeb: unknown dpkg-maintscript-helper command: dir_to_symlink

make: *** [binary] Error 25

dpkg-buildpackage: error: debian/rules binary gave error exit status 2

原因为dpkg的版本太低，导致部分命令无法正确执行，执行如下命令即可：

$ rm -rf debian/git.maintscript

# 重新编译 
$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

$ rm -rf debian/git.maintscript

# 重新编译

$ DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -d -b -uc

Building a minimal RootFS with Busybox, GLIBC and DropBear

Ubuntu 17.10上使用crosstool-ng-1.23.0建立WD MyCloud修复工具编译环境(uClibc)

参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)编译出来的Busybox是只有3MB大小的样子，这样编译出来的东西非常基础，功能有限。如果想要增加其他软件的时候，最少改动的情况下，一般都依赖GLIBC,而GLIBC完整编译出来的库接近50MB，而我们修复系统，是一个纯内存文件系统。直接采用GLIBC会非常浪费不多的内存空间。

因此在低内存的系统上采用uClibc，变成一个不错的选择。下面我们讲一下如何通过crosstool-ng-1.23.0构建一个我们需要的编译系统出来。

首先编译crosstool-ng-1.23.0源代码

$ sudo apt-get update
$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf
$ sudo apt-get -y install gperf
$ sudo apt-get -y install bison
$ sudo apt-get -y install flex
$ sudo apt-get -y install texinfo
$ sudo apt-get -y install help2man
$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf

$ sudo apt-get -y install gperf

$ sudo apt-get -y install bison

$ sudo apt-get -y install flex

$ sudo apt-get -y install texinfo

$ sudo apt-get -y install help2man

$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

如果下载crosstool-ng源代码存在问题，可以从本站下载一份代码拷贝。点击此处下载。

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

最终的.config文件，可以参考下面的配置信息，或者简单的拷贝这个文件到编译目录即可

编译过程中的源代码下载可能会非常缓慢，可以从本站下载一份代码的拷贝。点击这里下载。下载完成后，解压缩到当前用户根目录，编译的时候，会自动使用已经下载的文件。可以使用下面的命令进行下载解压缩操作：

$ cd ~

$ wget https://www.mobibrw.com/wp-content/uploads/2017/12/src.tar.xz

$ tar -xvf src.tar.xz

$ cd ~

$ wget https://www.mobibrw.com/wp-content/uploads/2017/12/src.tar.xz

$ tar -xvf src.tar.xz
