There are two types of passwords. User account passwords for the base operating system are stored as hashed values, do not need to be encrypted to be secure, and are saved in the system configuration backup. Other passwords, like iSCSI CHAP passwords, Active Directory bind credentials, and cloud credentials are stored in an encrypted form to prevent them from being visible as plain text in the saved system configuration.
The key or seed for this encryption is normally stored only on the boot device. Configuration backups containing the seed must be physically secured to prevent decryption of passwords and unauthorized access. The Include Password Secret Seed option is off by default and should only be used when making a configuration backup that will be stored securely. After moving a configuration to new hardware, media containing a configuration backup with a decryption seed should be securely erased before reuse.
Upload Config: allows browsing to the location of a previously saved configuration file to restore that configuration. Reset Config: reset the configuration database to the default base version. This does not delete user SSH keys or any other data stored in a user home directory. Since configuration changes stored in the configuration database are erased, this option is useful when a mistake has been made or to return a test system to the original configuration.
The network time protocol NTP is used to synchronize the time on the computers in a network. Accurate time is necessary for the successful operation of time sensitive applications such as Active Directory or other directory services. Figure 6. With multiple boot environments, the process of updating the operating system becomes a low-risk operation. The updater automatically creates a snapshot of the current boot environment and adds it to the boot menu before applying the update.
If an update fails, reboot the system and select the previous boot environment, using the instructions in If Something Goes Wrong , to instruct the system to go back to that system state. Boot environments are separate from the configuration database. Boot environments are a snapshot of the operating system at a specified time. As seen in Figure 6. The system will boot into the default boot environment and users can make their changes and update from this version.
The Initial-Install boot environment can be booted into if the system needs to be returned to a non-configured version of the installation. Using Clone to clone the active boot environment functions the same as using Create. If the system has a mirrored boot pool, there will be a Detach option in addition to the Replace option. Note that the boot device cannot be replaced if it is the only boot device because it contains the operating system itself.
If the system is currently booting from a device, another device can be added to create a mirrored boot device. If one device in a mirror fails, the remaining device can still be used to boot the system. When adding another boot device for a mirror, the new device must have at least the same capacity as the existing boot device.
Larger capacity devices can be added, but the mirror will only have the capacity of the smallest device. Different models of devices which advertise the same nominal size are not necessarily the same actual size. For this reason, adding another of the same model of boot device is recommended. In the example shown in Figure 6.
As shown in Figure 6. There is only one disk, indicated by the word stripe. If another device is available, it appears in the Member disk drop-down menu. Select the desired device. The Use all disk space option gives control of how much of the new device is made available to ZFS. The new device is partitioned to the same size as the existing device by default. Select Use all disk space to use all available space on the new device.
If either device in the mirror fails, it can be replaced with another of the same size as the original boot device. When Use all disk space is enabled, the entire capacity of the new device is used. If the original boot device fails and is removed, the boot mirror will consist of just the newer drive, and will grow to whatever capacity it provides. However, new devices added to this mirror must now be as large as the new capacity. After the mirror is created, the Boot Pool Status screen indicates that it is now a mirror.
The number of devices in the mirror are shown as in Figure 6. The configurable settings are summarized in Table 6. After the debug data is collected, the system prompts for a location to save the compressed. For example, if a pool exists on a system with limited RAM, the autotune script automatically adjusts some ZFS sysctl values in an attempt to minimize memory starvation issues. It should only be used as a temporary measure on a system that hangs until the underlying hardware issue is addressed by adding more RAM.
Autotune will always slow such a system, as it caps the ARC. Enable this option to run the autotuner at boot. To run the script immediately, reboot the system. These values can be modified and overridden. Note that deleting tunables that were created by autotune only affects the current session, as autotune-set tunables are recreated at boot.
When managing SED devices from the command line, it is important to use sedutil-cli rather than camcontrol to access the full capabilities of the device. By default, SED devices are not locked until the administrator takes ownership of them.
Once configured, the system automatically unlocks all SEDs during the boot process, without requiring manual intervention. This allows secure disposal of the device without having to first wipe its contents. If the device is instead removed to be repurposed on another system, it can only be unlocked if the password is known. It is important to remember the password! Without it, the device is unlockable and its data remains unavailable. While it is possible to specify the PSID number on the label of the device with the sedutil-cli command, doing so will erase the contents of the device rather than unlock it.
Always record SED passwords whenever they are configured or modified and store them in a safe place! When SED devices are detected during system boot, the middleware checks for global and device-specific passwords. Devices with their own password are unlocked with their password and any remaining devices, without a device-specific password, are unlocked using the global password.
Recording the password and storing it in a safe place is recommended. Conversely, the rows in that column will be empty for disks that do not support SED or which are unlocked using the global password. This command ensures that all detected SED disks are properly setup using the specified password.
Rerun sedhelper setup password every time a new SED disk is placed in the system. An automatic script sends a nightly email to the root user account containing important information such as the health of the disks. Alert events are also emailed to the root user account. Problems with Scrub Tasks are reported separately in an email sent at AM.
Instead, these emails are usually sent to an external email address where they can be read more conveniently. The first step is to set the remote address where email will be sent. In the Email field, enter the email address on the remote system where email is to be sent, like admin example. Click SAVE to save the settings. When the system dataset is moved, a new dataset is created and set active.
The old dataset is intentionally not deleted by the system because the move might be temporary or the information in the old dataset might be useful for later recovery.
The system dataset can optionally be configured to also store the system log and Reporting information. To store the system log on the system dataset, enable the Syslog option. To store the reporting information on the system dataset, enable the Reporting Database option.
You should not try to add these tunables back. The boot loader prompt provides a minimal set of commands described in loader 8.
Once at the prompt, use the unset command to disable a problematic value, the set command to modify the problematic value, or the unload command to prevent the problematic driver from loading. Example 6. The first command disables the current value associated with the kern.
The second command disables ACPI. The third command instructs the system not to load the fuse driver. When finished, type boot to continue the boot process. Any changes made at the boot loader prompt only effect the current boot. Enter search terms or a module, class or function name. Tests : allows you to schedule which S. Note due to a limitation in FreeBSD, users with account names that contain spaces or exceed 17 characters are unable to create cron jobs. The available fields and actions are as follows: Volume: the volume to be monitored for failover.
IP Address: the IP of the other device in the high availability setup. To configure rsync, you need to configure both ends of the connection: the rsync server: this system pulls receives the data. This system is referred to as PULL in the configuration examples.
This system is referred to as PUSH in the configuration examples. This mode requires that at least one module be defined on the rsync server. In other operating systems, the module is defined in rsyncd. Requires the configuration of SSH user and host public keys. It will be the rsync client, meaning that an rsync task needs to be defined. It will be referred to as PUSH. An rsync module needs to be defined on this system and the rsyncd service needs to be started.
It will be referred to as PULL. The key fingerprint is: f5:bdecfaa:bb:6e:a4:bb:df root freenas. Note if a different user account is used for the rsync task, use the su - command after mounting the filesystem but before generating the key. Note to prevent problems, do not enable the S. This tab also contains the following buttons: Factory Restore: resets the configuration database to the default base version.
Note it is important to configure the system so that it can successfully send emails. Use the drop-down menu to select the ZFS volume pool to contain the system dataset. OK unset kern. Table Of Contents 6. Thread starter meine Start date Jan 6, Tags boot loader. The FreeBSD boot menu has an option to choose 6. Configure Boot Options Escape to loader prompt' reveals that the default file in FreeBSD Snurg Daemon Reaction score: Messages: 1, You probably have to boot from rescue medium, mount the root filesystem and reverse that edit.
I had a similar problem recently, and when investigating this, it turned out that this is not straightforward on FreeBSD, because the developers decided to flag the root filesystem as "unmountable". Thus there are some additional steps involved to make the computer able to mount the root filesystem manually.
