mdadm.service is masked

[mdadm.service is masked]

No help here ?

I tried to install from this file mdadm_4.1-5ubuntu1_arm64.deb

The service seems to run :

sudo service mdadm status  
● mdadm.service - LSB: MD monitoring daemon
  Loaded: loaded (/etc/init.d/mdadm; generated)
  Active: active (exited) since Sun 2022-02-13 19:48:38 UTC; 1h 47min ago
    Docs: man:systemd-sysv-generator(8)
 Process: 310 ExecStart=/etc/init.d/mdadm start (code=exited, status=0/SUCCESS)

But i can't create a RAID volume :

sudo mdadm --create /dev/md0 --level=5 --raid-disks=5 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1
modprobe: FATAL: Module md_mod not found in directory /lib/modules/4.4.194
mdadm: Fail create md0 when using /sys/module/md_mod/parameters/new_array
mdadm: unexpected failure opening /dev/md0

 

Can some one help me about that ?

 

[mdadm.service is masked]

Hi everyone,

 

in Tinker Board 2 Debian 10 V2.0.0 OS when i try to start the mdadm service i have this message :

sudo service mdadm force-reload
Failed to restart mdadm.service: Unit mdadm.service is masked.

When i try this code nothing is changed :

sudo systemctl unmask mdadm-waitidle.service mdadm.service

 

Can it be fixed ?

Thanks !
