问题描述
我正在尝试从头开始在Docker中启动Tarantool（无现有数据）。我使用了Tutorial中建议的Docker命令，并在MacOS 10.15.6（Catalina）的Docker Desktop 2.4.0.0下运行它：
docker run \
--name mytarantool \
-d -p 3301:3301 \
-v /data/dir/on/host:/var/lib/tarantool \
tarantool/tarantool:2.5.1
（{/data/dir/on/host被替换为我在笔记本电脑上的本地目录）。我也尝试使用最新版本2.6.0。
容器在启动后不久终止。 docker logs显示如下：

与此同时，容器设法创建5.9K 00000000000000000000.snap和97B 00000000000000000000.xlog文件。
$ ls -hal

drwxr-xr-x@ 4 user staff 128B 2 Oct 13:51 .
drwxr-xr-x 3 user staff 96B 2 Oct 12:56 ..

-rw-r--r-- 1 user staff 97B 2 Oct 13:51 00000000000000000000.xlog
如果我在不装入本地目录的情况下启动了容器，则它将成功。
我认为我的本地文件系统有问题（或从容器中可见的方式），或者可能是权限问题，但我无法弄清楚到底是什么。
如果我exec作为成功启动的容器中的shell，我会看到xlog文件更大并且文件的所有者是tarantool:tarantool。
$ docker exec -it 016 sh
/opt/tarantool # ls -hal /var/lib/tarantool/

-rw-r--r-- 1 tarantoo tarantoo 273 Oct 2 20:40 00000000000000000000.xlog
但是在目录绑定的情况下，它看起来有所不同：
$ docker run -it -p 3031:3031 -v /Users/user/project/storage:/var/lib/tarantool tarantool/tarantool:2.6.0 sh
/opt/tarantool # ls -hal /var/lib/tarantool/

drwxr-xr-x 4 tarantoo root 128 Oct 2 21:18 .
drwxr-xr-x 1 root root 4.0K Aug 2 16:31 ..
-rw-r--r-- 1 root root 5.9K Oct 2 21:18 00000000000000000000.snap
-rw-r--r-- 1 root root 97 Oct 2 21:18 00000000000000000000.xlog
我试图更改目录和文件的所有者：
$ docker run -it -p 3031:3031 -v /Users/user/project/storage:/var/lib/tarantool tarantool/tarantool:2.6.0 sh
/opt/tarantool # chown tarantool:tarantool -R /var/lib/tarantool/
并在容器重启后检查更改是否仍然存在：
$ docker run -it -p 3031:3031 -v /Users/user/project/storage:/var/lib/tarantool tarantool/tarantool:2.6.0 sh
/opt/tarantool # ls -hal /var/lib/tarantool/
total 16
drwxr-xr-x 4 tarantoo tarantoo 128 Oct 2 21:18 .
drwxr-xr-x 1 root root 4.0K Aug 2 16:31 ..
-rw-r--r-- 1 tarantoo tarantoo 5.9K Oct 2 21:18 00000000000000000000.snap
-rw-r--r-- 1 tarantoo tarantoo 97 Oct 2 21:18 00000000000000000000.xlog
现在，权限看起来与工作容器中的权限相同。但是启动容器通常最终会导致相同的问题：
$ docker run -it -p 3031:3031 -v /Users/user/project/storage:/var/lib/tarantool tarantool/tarantool:2.6.0

奇怪的是，如果我在笔记本电脑上本地检查权限，则根本没有更改权限。我以为这是Docker的魔力，但考虑到容器重新启动之间的权限更改仍然存在，因此我不确定它是如何工作的。
但是也许问题与权限无关...然后呢？如何解决该问题？
解决方法
回答我自己的问题。
显然，此问题与权限无关，问题出在文件系统虚拟化级别。
可以通过在Docker桌面首选项中关闭“ gRPC FUSE”功能来解决此问题。大概是（如它所说的can't allocate disk space: Invalid argument），问题在于该实现不支持某些特定参数的fallocate()（请参见https://github.com/docker/for-mac/issues/4964#issuecomment-702748937）。
更新：如果您想使用gRPC FUSE功能进行文件共享，请考虑更新到已解决该问题的2.4.2.0版。
