当 sshfs 锁定时自动重置，重新挂载失败，除非手动完成

Question

我的服务器上有 2 个本地目录安装在远程服务器上。本地与 dirs-sshfs.sh 保持连接， autossh -M 23 -R 24:localhost:22 user@server而远程挂载

sshfs -o reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,cache_timeout=3600 [email protected]:/mnt/localdir1/ /home/user/dir1/ -p 24
sshfs -o reconnect,ServerAliveInterval=15,ServerAliveCountMax=3,cache_timeout=3600 [email protected]:/mnt/localdir2/ /home/user/dir2/ -p 24

当锁死时，使用sshfs-restart.sh重置连接

pkill -kill -f "sshfs"
fusermount -uz dir1
fusermount -uz dir2
./dirs-sshfs.sh

一切正常，但我必须 1）注意到它已锁定并 2）手动重置它。

棘手的是，当它锁定时，即使主目录的 ls 也会无限锁定，直到重置。因此，我放弃了从远程服务器端进行管理。在我的本地服务器端，维护 autossh 连接的地方，我有以下几乎可以工作的脚本。这会在失败时捕获，并尝试重置连接，但在卸载后不会重新安装。尝试将 dirs-sshfs.sh 内容放入 ssh-restart.sh 中，甚至 run-sshfs-restart.sh 包含的远程服务器端./sshfs-restart.sh &也无法使其工作。测试脚本（testsshfs2.sh）包含ls; echo; ls dir1; echo; ls dir2; echo; date; echo它，它的创建是为了快速、简单地检查所有内容是否已安装/工作。

这是 sshfsmanager.sh，使用 sleep 命令在 while 循环内从本地服务器运行。未来可能会将其转移到 cronjob

sshout=$(timeout 300 ssh user@host ./testsshfs2.sh)
# timeout duration probably doesnt need to be that long, but sometimes it does take 90+ sec to ls
# the remote dirs as they are network shares mounted to a vm that are then mounted across a ssh
# tunnel. Once this is working, that duration would be fine tuned. Also 100 is just an arbitrary
# number larger than ls | wc -l would provide. It should be updated to where it would catch if
# either of the mounts fail instead of only when both do. This timeout method is the only way
# ive found to get around the infinite ls lock.

if [ `echo "$sshout" | wc -l` -le 100 ]; then
  echo "$sshout" | wc -l
  ssh user@host ./sshfs-restart.sh
  #adding a "&& sleep 60" or using the run-sshfs-restart.sh script did not work

  echo sshfs restarted
else
  echo sshfs is fine
  echo "$sshout" | wc -l
fi

大多数脚本的日志记录在放置在这里时已被删除（以及更改端口和删除用户/主机）。大多数日志行只是日期>> sshfsmanager.log
