Synology UPS NUT
Synology UPS NUT
Synology UPS NUT (network UPS Tools), door aan een Synology NAS een UPS te koppelen wordt voorkomen dat er dataverlies optreedt of hardware stuk gaat bij een stroomstoring. Daarnaast kunnen ook andere apparaten een seintje krijgen om uitgezet te worden bij een stroomstoring. Synology has implemented NUT: http://networkupstools.org
De gebruikte configuratie voor Synology UPS NUT:
Synology NAS connected via Dataport to APC Back-UPS ES 700.
The configuration files on the Synology NAS are found here:
/usr/syno/etc/ups, which you can access via a terminal
upsd.conf
upsd.users
ups.conf
After changing the file you can reload the configuration:
upsd -c reload
Settings via the Synology GUI
GUI, control panel, Hardware & Power, General
restart automatically after a power failure
GUI, control panel, Hardware & Power,UPS
Select Enable Network UPS Server, Permitted Disk Station Devices.
Select the devices who are allowed to connect.
To get UPS status information from another device and user:
you have to be in the upsd.users file and be in the list of permitted disk station devices, (control panel, Hardware & Power, UPS)
run the following command to check UPS information and status from another device:
upsc <name ups, see NAS /usr/syno/etc/ups/ups.conf>@<ip address NAS>
for example upsc ups@192.168.1.10
To change a value for example for testing:
upsrw -s battery.charge.low=<new value> -u <user, defined in upsd.conf NAS> -p <password user in upsd.conf> <name ups, see NAS /usr/syno/etc/ups/ups.conf>@<ip address NAS>

Synology reset 2FA met SSH ingeschakeld
Synology reset 2FA legt uit hoe 2FA te resetten als SSH nog steeds ingeschakeld is. De commando’s worden uitgevoerd via een terminal sessie en SSH moet ingeschakeld zijn op de Synology NAS. In het geval dat er 1 administrator op de NAS is en 2FA moet gereset worden omdat alle 5 emergency codes verbruikt zijn is het nog mogelijk 2FA te resetten als SSH ingeschakeld is.
Synology terminal session
You have to make sure that SSH is enabled on the Synology NAS. This can be done from the control panel under Terminal & SNMP. For Windows you can use PuTTY to connect via SSH.
Zorg dat SSH is ingeschakeld op de Synology NAS. Dit kan in control panel onder Terminal & SNMP. Voor Windows kan je gebruik maken van PuTTY om een SSH verbinding te maken.

Synology rsync synchronisatie terminal
Synology rsync synchronisatie terminal
Synology rsync synchronisation terminal explains the steps to synchronise two shared folders via the rsync protocol. The rsync commando's are executed in a terminal session that's why SSH must be enabled on the Synology NAS. Be careful running the terminal commands because files and folders can be deleted, running the commands is at your own risk.

Terminal command:
ssh <admin user>@server
sudo -i
Turn on rsync on the Synology NAS-servers
To turn on rsync on the Synology NAS open control panel, file services, enable rsync service. Both Synology NAS-servers should have the rsync service running otherwise the Synology rsync synchronisation terminal commands don't run.
Identify both folders for Synology rsync synchronisation
Choose which folder on the source Synology NAS you want to synchronise to the other Synology NAS server which will be the destination. When the folder on the destination doesn't exits it will be created but not seen in the control panel as a shared folder. You can make it a shared folder afterwards and the synchronised data will not be overwritten. It is also possible to create first the shared folder on the destination NAS before the synchronisation. The advantage here is that the folder is created with the correct settings like permissions.
Hyper Backup and the difference with Synology rsync synchronisation terminal commands
With Hyper Backup you can create a rsync copy (single-version). The disadvantage from this way is that a subfolders are created under the destination shared folder and not directly inside the shared destination folder. The rsync job will create a backup folder and is not suitable for this purpose.
Shared Folder Sync and the difference with Synology rsync synchronisation terminal commands
When you have already on the destination, shared folders with identical names as the source shared folders, the folders at destination will be renamed! When the folders don't exists on the destination the will be created. When you already have a shared folder on the destination and the data is quit large, deleting the folder will take more time than to synchronise only the differences. After the creating of the shared folder at the destination you cannot access the files without changing the permissions. Also changing the files/folders at the destination after changing the permissions will not result in synchronising the source folders to the destination, running a full synchronisation does the job.
Synology rsync synchronisation terminal commands
Let me start by saying to be careful how you proceed with the following commands because they will overwrite and delete files and folder! So test first and check if the command is doing as expected.
Run the following Synology rsync synchronisation terminal commands at your own risk and first test before usage!!!!
Name Source Synology NAS server: server01
Name Destination Synology NAS server: server02
Shared folder on server01: test test
Shared folder on server02: test test
start terminal session on server01 or server02:
Terminal command:
ssh <admin user>@<servername>
sudo -i
command is run from server01 or server02:
Assumed volume1
Purpose: make source shared folder the same on the destination NAS.
Delete files/folders within the destination shared folder to make sure that the destination shared folder is the same as the source shared folder.
Running the Synology rsync synchronisation terminal command
Run the following Synology rsync synchronisation terminal commands at your own risk and first test before usage!!!!
from server 02:
rsync -avhz --delete <admin user>@server01:"'/volume1/test test/'" "/volume1/test test/"
from server 01:
rsync -avhz --delete "/volume1/test test/" <admin user>@server02:"'/volume1/test test/'"
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
-v, --verbose increase verbosity
-h human readable
-z, --compress compress file data during the transfer
-r, --recursive recurse into directories
-l, --links copy symlinks as symlinks
-p, --perms preserve permissions
-t, --times preserve modification times
-o, --owner preserve owner (super-user only)
-g, --group preserve group
--devices preserve device files (super-user only)
--specials preserve special files
-D same as --devices --specials
--delete delete files in the destination.

Purpose: make source shared folder the same on the destination NAS.
Secure copy files/folders within the source shared folder to the destination folder. Also copy hidden files.
Running the Synology scp command
Run the following scp command at your own risk and first test before usage!!!!
cd /volume1
pwd
scp -rp test\ test/. <admin user>@server02:"'/volume1/test test/'"
-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal
-p Preserves modification times, access times, and modes from the original file.
. Will copy also hidden files.

Synology change connection
Synology change connection shows how to change the connection without a new synchronisation. Sometimes you cannot change the connection because it is grayed out and you have to unlink first and make a new connection.
Synology change connection settings Cloud Station ShareSync:
1. Use Chrome to login DSM and launch Cloud Station ShareSync to start editing the connection of the task.
2. Enable the Developer Tools:
3. Go to the Console tab:
4. Input the following command and hit enter:
document.querySelector(“.syno-dscc-create-wizard input[name=address]”).disabled = false;
5. Now it’s possible to edit the server address even it’s still greyed out:
6. Once it’s done, click on “Apply” to confirm and Cloud Station ShareSync would start connecting to the newly specified server address:

Synology Terminal Mount Volume & Map
Synology Terminal Mount Volume & Map
Synology Terminal Mount Volume & Map shows commands you can execute via the terminal to mount volumes or encrypted shared folders. Always contact Synology support first for help and follow their directions and make sure you have a working backup. If you like to try it is on your own risk!
Always contact Synology support first for help and make a working backup first. Use this steps on your own risk!
Synology Terminal Mount after a crashed volume:
after a crashed volume which is not recoverable from the GUI you can try to mount the volume as read-only in a terminal.
Make terminal ssh connection to Synology NAS.
cat /etc/fstab
fdisk -l
cat /proc/mdstat
mdadm --detail /dev/<mdX, check cat /proc/mdstat>
check md not listed. For example md9
use at own risk:
mdadm -A -R /dev/<md not listed> /dev/<disk not crashed> /dev/<disk not crashed>
-A, --assemble Assemble a pre-existing array
-R, --run Attempt to start the array even if fewer drives were given than are needed for a full array. Normally if not all drives are found and --scan is not used, then the array will be assembled but not started. With --run an attempt will be made to start it
anyway.
command should return the message "mdadm: /dev/<md not listed> has been started with x drives."
lvm vgscan : take note of volume group name
vgchange -a y <volume group name, for example:vg1000>
-a, --activate
The command to mount the volume as read-only in order:
mount -o ro,noload /dev/<volume group name>/lv /volume1
volume group must exists on your system.
the volume should be reachable in the terminal session.

Synology Terminal Mount encrypted map:
Always contact Synology support first for help and make a working backup first. Use this steps on your own risk!
You need the password to decrypt the shared folder.
If you don't have the password but you have the key file, you can run the following command to retrieve the password, I used a Ubuntu Linux system with ecryptfs-utils installed.
printf "%s" "\$1\$5YN01o9y" | ecryptfs-unwrap-passphrase <keyfile.key>
Make terminal ssh connection to Synology NAS.
cd /volume<>
ls -al
check your folders, for example an encrypted folder named encrypt
@encrypt@ and encrypt
If only @encrypt@ exits and not encrypt this could mean the @encrypt@ folder is not mounted on mount point encrypt.
check with ls command the ls
ls -al @encrypt@ and ls-al encrypt
mount
and check it encrypted folder is mounted ( for example):
when it is mounted it will show:
/volume1/@encrypt@ on /volume1/encrypt type ecryptfs (rw,relatime,ecryptfs_fnek_sig=<>,ecryptfs_sig=<>,ecryptfs_cipher=aes,ecryptfs_key_bytes=32,ecryptfs_unlink_sigs)
when encrypt is not mounted it will not show this line after the mount command.
to mount the @encrypt@ folder on mount point encrypt.
first check if encrypt folder exists.
if not exits run mkdir encrypt ( this directory wil be deleted after encrypting the folder from the GUI, the folder cannot be removed with the rm command)
to mount:
mount.ecryptfs \@encrypt\@/ encrypt/
Passphrase: <fill in the password used to encrypt the folder, without the password you cannot see your data>
Select cipher:
1) aes: blocksize = 16; min keysize = 16; max keysize = 32
