Mount point permission was changed

Hello everybody,

I have many mount points on my virtual Redhat server, two of them lost their (write) permission, so they became read-only filesystems.

I fixed this problem.
But I want to know why it happened? What is the reason behind that to avoid it again? Where can I find related logs?

Many thanks for reading.

automountd(1M)															    automountd(1M)

NAME
automountd - autofs mount/unmount daemon SYNOPSIS
name=value] DESCRIPTION
is an RPC server that answers file system mount and unmount requests from the filesystem. It uses local files or name service maps to locate filesystems to be mounted. These maps are described with the command (see automount(1M)). The daemon is automatically invoked if the variable is set to 1 in Options Trace. Expand each RPC call and display it to Verbose. Log status messages to Turn off browsing for all mount points. This option overrides the map option on the local host. Force all mounts to the local host to be NFS mounts instead of the default LOFS mounts. This is necessary for highly available NFS mounts. Assign value to the indicated map substitution variable. These assignments cannot be used to substitute variables in the master map Tracing While is running, the signal can be sent to to turn tracing on. It logs messages in To turn tracing off, send the signal again. RETURN VALUE
returns: 0 successful 1 failure EXAMPLES
To turn on tracing, enter: or No messages are displayed by the trace. Check the results in WARNINGS
Any filesystems that are being managed by should never be manually mounted or unmounted. Even if the mount or unmount operation appears to complete successfully, the resulting change of state to the managed filesystem can lead to disruptive or unpredictable results, including but not limited to: commands hanging or not returning expected results, and applications failing due to their dependencies on those mounted filesystems. A reboot may be necessary to resolve these issues. AUTHOR
