![]() ![]() Prevents the file system from being mounted automatically when mount The number of loop devices that you require (from 0 to Parameter max_loop= N to configure up to 255 devices. The default number of available loop devices is 8. Or, you can specify the block device if it's mounted on only one mount point.įor more information, see the mount(8) and Sudo touch /mnt/foo sudo mount -M /mnt/foo /mnt/bar To move a mounted file system, directory hierarchy, or fileīetween mount points, use the -M option, for To prevent a mount from being mirrored by using the Mirrors, but this mount hierarchy does reflect mounts or unmount changes that you make Mirrors, nor does this mount hierarchy reflect mounts or unmount changes that you make You create, and this mount hierarchy reflects mounts or unmount changes that you make toĪny mounts or unmounts under the specified mount point don't propagate to other Specify the following options: mount -make-sharedĪny mounts or unmounts under the specified mount point propagate to any mirrors that ![]() ![]() You can mark the submounts in a mount point as being shared, private, or secondary. Mount options, use a separate remount command, for example: System mount options remain the same as those for the original mount point. When you use the -B or -R option, the file To include submounts in the mirror, use the -R option to create a The existing file that acts as a mount point isn't accessible In the previous example, the /etc/hosts and /mnt/foo mount Sudo touch /mnt/foo sudo mount -B /etc/hosts /mnt/foo To mount a file over another file, you would use the following ![]() However, any submounts aren't replicated.
