How to translate what we had to do to have 2 independent stream of traffic on 2 or more NIC interfaces with the new netplan.io + systemd-networkd?

auto ens2
iface ens2 inet static
address 192.168.5.100
netmask 255.255.255.0
gateway 192.168.5.1
dns-nameservers 1.1.1.1

auto ens3
iface ens3 inet static
address 192.168.3.15
netmask 255.255.255.0


up ip route add default table 102 dev ens3 via 192.168.3.1
up ip rule add from 192.168.3.0/24 lookup 102
down ip rule del from 192.168.3.0/24
down ip route del default table 102 via 192.168.3.1
routing 18.04 netplan nic

Does anyone knows why have I this message with the new update of samba on ubuntu 16.04.1?

Paramétrage de samba (2:4.3.9+dfsg-0ubuntu0.16.04.3) ...
Failed to add /run/systemd/ask-password to directory watch: No space left on device:

Since I have so much space, I don't understand :

everything is in the title. I have to specify that the restart wasn't initiated by me. The command was : sudo mdadm --grow /dev/md227 --level=6 --raid-devices=7 --backup-file=/root/raid5backup

I have read here that it wasn't catastrophic if it was a clean shutdown. here is the state of the RAID now:

/dev/md227:
        Version : 1.2
     Raid Level : raid0
  Total Devices : 7
    Persistence : Superblock is persistent

          State : inactive

      New Level : raid6
     New Layout : left-symmetric
  New Chunksize : 512K

           Name : DOCKER-BATCAVE:227
           UUID : 837da647:3c4431c9:607feb30:b887f4fd
         Events : 1901220

    Number   Major   Minor   RaidDevice

       -       8      176        -        /dev/sdl
       -       8       17        -        /dev/sdb1
       -       8       33        -        /dev/sdc1
       -       8       49        -        /dev/sdd1
       -       8       65        -        /dev/sde1
       -       8       81        -        /dev/sdf1
       -       8      113        -        /dev/sdh1

What should I do? or What can I do? Re create a raid 5 on the 6 original disc to hope to retrieve some files? Or --grow--continue will work? how do I indicate to the grow continue to use the backup-file already created ?

thanks for any help you could provide

EDIT: I forgot to say that the raid was managed with LVM. EDIT: sorry for the multiple EDIT but the event didn't occur when I was busy with server.

I have done multiple researchs before to open this post. I did find a lot of post about it but none was really link to my configuration so I open this here. I have 2 hdd in RAID 1:

Disque /dev/sdj : 558,9 GiB, 600127266816 octets, 1172123568 secteurs
Unités : sectors of 1 * 512 = 512 octets

/dev/sdk2    1171875840 1953523711  781647872 372,7G Linux filesystem

sdj1 + sdk1 = RAID1

I'm adding 2 other disks with this procedure from this [tuto]: https://ubuntuforums.org/showthread.php?t=713936 for the partitionning: 

`sfdisk /dev/sdd < partitions.sdb`

It has worked before for another RAID on the same host. So I end up with :

Disque /dev/sdg : 931,5 GiB, 1000204886016 octets, 1953525168 secteurs
Unités : sectors of 1 * 512 = 512 octets

Disque /dev/sdi : 931,5 GiB, 1000204886016 octets, 1953525168 secteurs
Unités : sectors of 1 * 512 = 512 octets
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

/dev/sdi2    1171875840 1953523711  781647872 372,7G Linux filesystem

and so :

Personalities : [raid1] [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid10] 
md125 : inactive sdn[0]
      976224256 blocks super external:/md126/0

md126 : inactive sdn[0](S)
      538328 blocks super external:ddf

md227 : active raid6 sdl[7] sdh1[6] sde1[5] sdf1[4] sdd1[3] sdc1[0] sdb1[1]
      9766912000 blocks super 1.2 level 6, 512k chunk, algorithm 18 [7/6] [UUUUUU_]
      [=========>...........]  reshape = 46.8% (915172352/1953382400) finish=3557.0min speed=4864K/sec
      bitmap: 2/15 pages [8KB], 65536KB chunk

md127 : active raid1 sdg1[3](S) sdk1[2](S) sdj1[0] sdi1[1]
      585805824 blocks super 1.2 [2/2] [UU]
      bitmap: 4/5 pages [16KB], 65536KB chunk

unused devices: <none>

md127 is the raid1 as you see I'm growing a raid5 in a raid6 at the same time.

Why have I this: mdadm: Impossibly level change request for RAID1

with this : sudo mdadm --grow /dev/md127 --level=10 --raid-devices=4 --backup-file=/root/raid1backup

because of the growing of the RAID6? or the partitionning is not good? or is it because the raid array is mounted and busy with docker container?
