深海游弋的鱼 – 默默的点滴

Debian10升级11（buster升级bullseye）

2021年8月14日，Debian11正式发布了，代号“bullseye” Debian 11 (bullseye), 64-bit PC 的发行说明

下面演示下Debian10升级到Debian11

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。

Debian旧版本源同步脚本

最近 Debian Wheezy/Jessie 源被官方归档了，使得许多来不及更新系统的服务器没源可用，http://archive.debian.org 访问速度太慢，不得以自己写个脚本同步 Wheezy/Jessie 源。

Debian 官方推荐使用 debmirror 同步源，但是在群晖等设备上不方便使用，因此还是用 rsync 同步通用一些。

主要是自己的 WD MyCloud Gen1 在编译软件的时候，依赖 Wheezy ，Jessie 版本的软件包，又没办法升级系统，只能是自己建立软件源，保存一下，免得日后麻烦。

由于 Debian 源的结构，要单独分版本来同步很不方便，包都集中在 /pool 目录下，故此脚本主要根据索引文件来生成该版本的包列表ARCH_EXCLUDE 用来过滤不同架构的包的dists 用来过滤不同版本的同步完成后，整个 Wheezy/Jessie 源（i386, amd64, arm, source) 共 96G

Wheezy Archive 源设置

deb http://mirrors.163.com/debian-archive/ wheezy main contrib non-free
deb-src http://mirrors.163.com/debian-archive/ wheezy main contrib non-free

1 2	deb http://mirrors.163.com/debian-archive/ wheezy main contrib non-free deb-src http://mirrors.163.com/debian-archive/ wheezy main contrib non-free

OpenmediaVault-4.1.3上编译Linux Kernel 4.14.118

也可以使用下面的方式正常编译 Linux Kernel 4.14.118 。

建议使用 VirtualBox 上建立虚拟机，保证磁盘空间不小于 32GB，给 root 用户设置密码，远程通过 shell 登录到虚拟机。

查询虚拟机的 IP地址的时候，使用

# Debian 9 系统上 ip 命令替代了ifconfig
$ ip addr

1 2	# Debian 9 系统上 ip 命令替代了ifconfig $ ip addr

命令查询。虚拟机网卡设置的时候，设置为桥接模式，默认的 NAT 模式无法通过 SSH 登录。

然后执行如下命令：

# 解压缩xz格式的linux内核
$ sudo apt-get install xz-utils

$ cd ~

$ wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.118.tar.xz -O linux-4.14.118.tar.xz

$ tar -zxvf linux-4.14.118.tar.xz

$ cd linux-4.14.118/

# 升级系统工具，如果不更新，有时候会出现无法编译的情况
$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get install make

$ sudo apt-get install build-essential

$ sudo apt-get install kernel-package

$ sudo apt-get install ncurses-dev

$ sudo apt-get install libelf-dev

#一路回车到底
$ make oldconfig

$ make-kpkg --initrd kernel-image kernel_headers

# 解压缩xz格式的linux内核

$ sudo apt-get install xz-utils

$ cd ~

$ wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.118.tar.xz -O linux-4.14.118.tar.xz

$ tar -zxvf linux-4.14.118.tar.xz

$ cd linux-4.14.118/

# 升级系统工具，如果不更新，有时候会出现无法编译的情况

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get install make

$ sudo apt-get install build-essential

$ sudo apt-get install kernel-package

$ sudo apt-get install ncurses-dev

$ sudo apt-get install libelf-dev

#一路回车到底

$ make oldconfig

$ make-kpkg --initrd kernel-image kernel_headers

完成后，在当前用户目录下生成 linux-image-4.14.118_4.14.118-10.00.Custom_amd64.deb 安装包,执行如下命令安装：

$ cd ~

$ sudo dpkg -i linux-image-4.14.118_4.14.118-10.00.Custom_amd64.deb

$ cd ~

$ sudo dpkg -i linux-image-4.14.118_4.14.118-10.00.Custom_amd64.deb

解决Btrfs文件系统ext2_saved文件磁盘占用异常

最近在 OpenMediaVault 4.1.22-1(Arrakis) 进行磁盘文件占用分析的时候，发现磁盘空间异常占用问题，如下：

root@openmediavault:/media/6357625f-c966-49ba-9c90-9e8f8ff50433# du -ah --max-depth=1
0	./lost+found
1.5T	./MyCloud
8.0K	./aquota.user
8.0K	./aquota.group
1.3T	./ext2_saved
4.0K	./WDMyCloudSync.sh
2.7T	.

root@openmediavault:/media/6357625f-c966-49ba-9c90-9e8f8ff50433# du -ah --max-depth=1

0 ./lost+found

1.5T ./MyCloud

8.0K ./aquota.user

8.0K ./aquota.group

1.3T ./ext2_saved

4.0K ./WDMyCloudSync.sh

2.7T .

这个 1.3T ./ext2_saved 文件是不存在的，并且没办法通过常规命令删除。

这个文件产生的原因是，执行过从 EXT3/4 转换转化分区到 Btrfs :

$ btrfs-convert /media/6357625f-c966-49ba-9c90-9e8f8ff50433

1	$ btrfs-convert /media/6357625f-c966-49ba-9c90-9e8f8ff50433

完成转换需要删除备份的 ext2_saved 子卷,否则空间会不能释放。请注意，如果没了它(备份子卷)，你将没办法还原回 EXT3/4 文件系统。

$ sudo apt-get install btrfs-tools

# 执行，然后无视报错
$ btrfs subvolume delete /media/6357625f-c966-49ba-9c90-9e8f8ff50433/ext2_saved

$ sudo apt-get install btrfs-tools

# 执行，然后无视报错

$ btrfs subvolume delete /media/6357625f-c966-49ba-9c90-9e8f8ff50433/ext2_saved

可能会报错：

ERROR: cannot access subvolume /media/6357625f-c966-49ba-9c90-9e8f8ff50433/ext2_saved: No such file or directory

1	ERROR: cannot access subvolume /media/6357625f-c966-49ba-9c90-9e8f8ff50433/ext2_saved: No such file or directory

无视这个报错即可。

完成后再次查询文件占用空间：

root@openmediavault:/media/6357625f-c966-49ba-9c90-9e8f8ff50433# du -ah --max-depth=1
0	./lost+found
1.5T	./MyCloud
8.0K	./aquota.user
8.0K	./aquota.group
4.0K	./WDMyCloudSync.sh
1.5T	.

root@openmediavault:/media/6357625f-c966-49ba-9c90-9e8f8ff50433# du -ah --max-depth=1

0 ./lost+found

1.5T ./MyCloud

8.0K ./aquota.user

8.0K ./aquota.group

4.0K ./WDMyCloudSync.sh

1.5T .

可以看到空间已经被释放了。

解决VirtualBox无法共享粘贴板的问题(Debian)

一直使用VirtualBox安装的Debian环境编译WD MyCloud的代码。但是最近VirtualBox升级后，升级增强功能，然后共享粘贴板就不能使用了。

如果执行

可看到错误信息：

VBoxClient: Failed to connect to the VirtualBox kernel service, rc=VERR_FILE_NOT_FOUND

在WDMyCloud中安装的时候执行如下命令:

$ sudo apt-get install -y --force-yes php7.1

$ sudo apt-get install -y --force-yes libapache2-mod-php7.1

$ sudo apt-get install -y --force-yes php-apcu

$ sudo apt-get install -y --force-yes php-apcu-bc

$ sudo apt-get install -y --force-yes php7.1-xml

#这个是个坑，如果没有增加这个模块，也是可以正常启动的，但是却没办法正常登录进入，应用会出现异常
$ sudo apt-get install -y --force-yes php7.1-mbstring

#由于PHP7中的parse_ini_file不再兼容“#”作为注释字符，只能使用“;”进行注释，但是这个注释无法
#被其他应用读取，而WDMyCloud里面的其他脚本也需要读取/etc/system.conf里面的内容
#目前唯一的解决方法就是删除全部的注释行

注意，这部分的功能目前仅仅是可用，还没有达到完全正常的情况，如果出现问题，可以切换回PHP5,目前已知的完美切换回到原来的PHP5的办法就是卸载上面安装的所有PHP7的相关应用才能切换成功，否则总有部分小功能不是太正常.
