Ubuntu 升级后 运行 奇点时出现 squashfs 错误
squashfs error when running singularity after Ubuntu upgrade
概览:
我正在 运行ning Ubuntu 18.04 机器上处理奇点图像中的代码。截至周二晚上，它在机器 A 上运行（好吧，我正在调试代码）。我 运行 更新了，从第二天开始，任何对 运行 any 奇点容器的尝试都给我以下错误：
ERROR : Failed to mount squashfs image in (read only): Invalid argument
ABORT : Retval = 255
确认这不是我的代码造成的（通过 运行ning singularity exec <my_image_file>.sif 并得到同样的错误，我记得我在另一台机器上有几乎相同的设置（B)。我能够运行那里的图像没有任何问题。
不幸的是，我忘记了我在那台机器上选择了“无人值守更新”并重新启动。现在 returns 同样的错误。
我的尝试:
我这里有点空虚。我所做的只是说服自己，它与我的代码没有直接关系，而且几乎可以肯定与更新的 something 相关。我真的对 squashfs 知之甚少，而且对 singularity 还比较陌生。我还没有在网上找到任何有这个确切错误的东西（“无效参数”部分）。作为万福玛丽，我在机器 A 上重新安装了奇点，但它没有改变。
我不认为这是奇点本身的问题，而且我使用的是旧版本，所以我认为这不是一个有效的 github 问题。我使用的是 2.5.2 版，因为这是此代码适用于集群的版本。

该图像是根据 Docker 图像构建的，并经过一些额外的步骤。我没有提供任何相关信息，因为行为似乎并不取决于我何时构建图像。
我遇到了这个确切的问题，我设法在 Ubuntu 18.04 中使用奇点版本 2.6.1 修复了它（不过我认为在 2.5.2 中解决方案对你来说不会有太大不同）。
要采取的步骤
如果需要请卸载早期版本的 Singularity。
通过打开终端和运行以下命令下载正确的 Singularity 版本的 tarball：
# Go to the place you want to work in
cd ~
VERSION=2.6.1 # Set an environment variable just for convenience, could replace with another version.
# Download
wget https://github.com/singularityware/singularity/releases/download/$VERSION/singularity-$VERSION.tar.gz
# Extract
tar xvf singularity-$VERSION.tar.gz
现在，应该有一个文件夹叫singularity-2.6.1（我是放在首页（~）。然后打开文件mount.c放在singularity-2.6.1/src/lib/image/squashfs/mount.c（我不确定 v2.5.2 是否相同，但我认为变化不大。不过我们可能运气不好）
在此文件中找到代码行
if ( singularity_mount(loop_dev, mount_point, "squashfs", MS_NOSUID|MS_RDONLY|MS_NODEV, "errors=remount-ro") < 0 )
改为
if ( singularity_mount(loop_dev, mount_point, "squashfs", MS_NOSUID|MS_RDONLY|MS_NODEV, "") < 0 )
别忘了保存！
- Return 到终端，通过 运行 命令
从编辑的安装文件安装 Singularity
cd singularity-$VERSION
./configure --prefix=/usr/local
make
sudo make install
对我来说，问题现在已经解决了！
编辑
正如 aguadopd 所指出的，如果您没有安装 libarchive-dev，make 命令可能无法工作。如果是这种情况，那么首先在终端 运行 中修复它
sudo apt-get update -y
sudo apt-get install -y libarchive-dev
然后在一个新终端
singularity shell -p $HOME/Downloads/hrwros-09.simg
问题原理
显然，squashfs 中曾经有一个错误，如果它不知道，它就会简单地忽略参数。当今年早些时候修复此问题时，它会在遇到无效参数时开始出错，就像我们的案例一样。 （这里也有解释https://www.mail-archive.com/debian-kernel@lists.debian.org/msg117435.html）
因此，删除未知参数 "errors=remount-ro" 解决了问题。
老实说，由于我是 100% 的新手，所以我不确定它是否会在其他地方引起任何新的错误。然而，这也是在后来的 Singularity (https://github.com/hpcng/singularity/pull/4802/files/3f3136be150d9a8f63e58a0b4e39dc8487f1c0dc) 版本中基本修复此错误的方式。
希望对您有所帮助！
谢谢。我按照你的步骤做了，成功了。
但是，我在“make”步骤中遇到了问题。它没有用，因为我没有安装“libarchive-dev”。为了修复它，我做了
- sudo apt-get update -y
- sudo apt-get install -y libarchive-dev
然后在一个新终端
- 奇点shell -p $HOME/Downloads/hrwros-09.simg
现在可以使用了。

该图像是根据 Docker 图像构建的，并经过一些额外的步骤。我没有提供任何相关信息，因为行为似乎并不取决于我何时构建图像。
我遇到了这个确切的问题，我设法在 Ubuntu 18.04 中使用奇点版本 2.6.1 修复了它（不过我认为在 2.5.2 中解决方案对你来说不会有太大不同）。
要采取的步骤
如果需要请卸载早期版本的 Singularity。
通过打开终端和运行以下命令下载正确的 Singularity 版本的 tarball：
# Go to the place you want to work in
cd ~
VERSION=2.6.1 # Set an environment variable just for convenience, could replace with another version.
# Download
wget https://github.com/singularityware/singularity/releases/download/$VERSION/singularity-$VERSION.tar.gz
# Extract
tar xvf singularity-$VERSION.tar.gz
现在，应该有一个文件夹叫
singularity-2.6.1（我是放在首页（~）。然后打开文件mount.c放在singularity-2.6.1/src/lib/image/squashfs/mount.c（我不确定 v2.5.2 是否相同，但我认为变化不大。不过我们可能运气不好）在此文件中找到代码行
if ( singularity_mount(loop_dev, mount_point, "squashfs", MS_NOSUID|MS_RDONLY|MS_NODEV, "errors=remount-ro") < 0 )
改为
if ( singularity_mount(loop_dev, mount_point, "squashfs", MS_NOSUID|MS_RDONLY|MS_NODEV, "") < 0 )
别忘了保存！
- Return 到终端，通过 运行 命令 从编辑的安装文件安装 Singularity
cd singularity-$VERSION
./configure --prefix=/usr/local
make
sudo make install
对我来说，问题现在已经解决了！
编辑
正如 aguadopd 所指出的，如果您没有安装 libarchive-dev，make 命令可能无法工作。如果是这种情况，那么首先在终端 运行 中修复它
sudo apt-get update -y
sudo apt-get install -y libarchive-dev
然后在一个新终端
singularity shell -p $HOME/Downloads/hrwros-09.simg
问题原理
显然，squashfs 中曾经有一个错误，如果它不知道，它就会简单地忽略参数。当今年早些时候修复此问题时，它会在遇到无效参数时开始出错，就像我们的案例一样。 （这里也有解释https://www.mail-archive.com/debian-kernel@lists.debian.org/msg117435.html）
因此，删除未知参数 "errors=remount-ro" 解决了问题。
老实说，由于我是 100% 的新手，所以我不确定它是否会在其他地方引起任何新的错误。然而，这也是在后来的 Singularity (https://github.com/hpcng/singularity/pull/4802/files/3f3136be150d9a8f63e58a0b4e39dc8487f1c0dc) 版本中基本修复此错误的方式。
希望对您有所帮助！
谢谢。我按照你的步骤做了，成功了。 但是，我在“make”步骤中遇到了问题。它没有用，因为我没有安装“libarchive-dev”。为了修复它，我做了
- sudo apt-get update -y
- sudo apt-get install -y libarchive-dev
然后在一个新终端
- 奇点shell -p $HOME/Downloads/hrwros-09.simg
现在可以使用了。
