I've created a partition with GNU Parted, how do I mount the partition?
The manual information at http://www.gnu.org/software/parted/manual/parted.html is good, but I am sure about how I mount the partition afterwards.
Thanks,

drbd_selinux
drbd_selinux(8) SELinux Policy drbd drbd_selinux(8)
NAME
drbd_selinux - Security Enhanced Linux Policy for the drbd processes
DESCRIPTION
Security-Enhanced Linux secures the drbd processes via flexible mandatory access control.
The drbd processes execute with the drbd_t SELinux type. You can check if you have these processes running by executing the ps command with
the -Z qualifier.
For example:
ps -eZ | grep drbd_t
ENTRYPOINTS
The drbd_t SELinux type can be entered via the drbd_exec_t file type.
The default entrypoint paths for the drbd_t domain are the following:
/usr/lib/ocf/resource./linbit/drbd, /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbdsetup
PROCESS TYPES
SELinux defines process types (domains) for each process running on the system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux drbd policy is very flexible allowing users to setup their drbd pro-
cesses in as secure a method as possible.
The following process types are defined for drbd:
drbd_t
Note: semanage permissive -a drbd_t can be used to make the process type drbd_t permissive. SELinux does not deny access to permissive
process types, but the AVC (SELinux denials) messages are still generated.
BOOLEANS
SELinux policy is customizable based on least access required. drbd policy is extremely flexible and has several booleans that allow you
to manipulate the policy and run drbd with the tightest access possible.
If you want to allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.
setsebool -P daemons_dump_core 1
If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.
setsebool -P daemons_enable_cluster_mode 1
If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.
setsebool -P daemons_use_tcp_wrapper 1
If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

If you want to deny any process from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
default.

file types. Note the processes UID still need to have DAC permissions.

FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files. SELinux drbd policy is very flexible allowing users to setup their drbd
processes in as secure a method as possible.
STANDARD FILE CONTEXT
SELinux defines the file context types for the drbd, if you wanted to store files with these types in a diffent paths, you need to execute
the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t drbd_exec_t '/srv/drbd/content(/.*)?'
restorecon -R -v /srv/mydrbd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for drbd:
drbd_exec_t
- Set files with the drbd_exec_t type, if you want to transition an executable to the drbd_t domain.
Paths:
/usr/lib/ocf/resource./linbit/drbd, /sbin/drbdadm, /sbin/drbdsetup, /usr/sbin/drbdadm, /usr/sbin/drbdsetup
drbd_initrc_exec_t
- Set files with the drbd_initrc_exec_t type, if you want to transition an executable to the drbd_initrc_t domain.
drbd_lock_t
- Set files with the drbd_lock_t type, if you want to treat the files as drbd lock data, stored under the /var/lock directory
drbd_var_lib_t
- Set files with the drbd_var_lib_t type, if you want to store the drbd files under the /var/lib directory.
Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use
the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
COMMANDS
semanage fcontext can also be used to manipulate default file context mappings.
semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage boolean can also be used to manipulate the booleans
system-config-selinux is a GUI tool available to customize SELinux policy settings.
