Fstab files are familiar to everyone. During Linux Startup, each partition is mounted through the information in fstab. A typical partition entry is like this: /Dev/sdb5/mnt/USB vfat utf8, umask = 0 0 0 /Dev/sda4 is the partition to be mounted, and sda4 is a LinuxThe name of the partition in sequence when detecting the hard disk. Generally, this name will not change, but if you have multiple hard disks an

It is found that there are many problems if the character is poor and the fstab is written incorrectly at night. As a result, the system cannot get up. Because the fault was not handled at the time, I found several images online, general Instructions When the system starts, filesystems fails. Enter the root password to enter repair filesystem mode. Try to modify/etc/fstab and find that the system is in

Linux fstab solves the problem that a server has not been maintained for a long time recently. After the system is restarted, the system enters the repair system mode. However, the/etc/fstab file is empty.

In Ubuntu, it is found that the system uses a UUID to make a unique representation of the hard disk partition, such as: #/DEV/SDA1#UUID =45f8-9147/media/sda1 vfat defaults,utf8,umask=000 0 1/DEV/SDA1/MEDIA/SDA1 vfat defaults,utf8,umask=000 0 1#/DEV/SDA5Uuid=5668d81168d7edad/media/sda6 ntfs-3g defaults,nls=utf8,umask=000 0 1 One advantage of doing this and using the/dev/sda5 method of direct reference partitioning is that when a new partition is added to the hard disk or the order of the partit

Some time ago, I made a few brief analyses on the Android SDCard unmount process. Since it was just a conversation on paper and there was no actual follow-up, there may be some misleading or minor errors. Today, I reorganized my mind and analyzed the mount process again.Outline How does the android system start listening to the mount service? Which directory of the Android system is the default mount point? Analysis of vold.
