我将 /dev/sdb1 挂载到 /media/zm_recordings。我使用的是 LSI 9211-4i RAID 控制器，其中有两个 500GB 磁盘，组成 RAID 1。Megaraid 管理器显示磁盘和卷运行正常。（底部截图）
fdisk 输出：

getegid() = 0
getuid() = 0
getgid() = 0
access("/run/mount", R_OK|W_OK) = 0
mount("/dev/sdb1", "/media/test", "ext4", 0, NULL
再次，bash 不会在这里输出任何内容，ctrl + c 除了打印 ^C 之外不执行任何操作。
不知道接下来该怎么做。还有其他我可以执行的检查吗？我附上了 RAID 状态屏幕的屏幕截图，我似乎无法让 megacli/storcli 工作，但我会继续尝试修复它。（我可能错了，但我认为下面的 storcli 命令不起作用，因为您必须对像我拥有的那种旧 raid 卡使用 megacli。）
sudo storcli 显示全部：
Status Code = 0
Status = Success
Description = None
Number of Controllers = 0
Host Name = debian-zm
Operating System = Linux4.19.0-6-amd64
答案1
这几乎肯定是文件系统损坏。在命令挂起时，检查最后几行dmesg，应该会发现问题。
重新启动会重新安装卷并最终重播日志。但是，如果某些损坏的元数据隐藏在某处，它会在某个时刻再次冻结。e2fsck卸载卷后，您一定要在卷上运行它。
