SG450 UTM RAID degraded

SG450 UTM shows RAID status as degraded.

Is there a way to check the status via CLI?

what i found so far is:

ictrz-fw-01:/home/login # lsblk

NAME      MAJ:MIN RM   SIZE RO MOUNTPOINT

sda         8:0    0 223.6G  0

├─md0       9:0    0 223.6G  0

│ ├─md0p1 259:0    0   350M  0 /boot

│ ├─md0p2 259:1    0     4G  0 [SWAP]

│ ├─md0p3 259:2    0   1.5G  0

│ ├─md0p5 259:4    0    89G  0 /var/storage

│ ├─md0p6 259:5    0   5.4G  0 /

│ ├─md0p7 259:6    0 116.6G  0 /var/log

│ └─md0p8 259:7    0   4.7G  0 /tmp

└─md127     9:127  0         0

sdb         8:16   0    32K  0

should sdb have the same partition table as sda ?

further more we can see LOTS of fatal error messages (2gig per day) of the following message in the log:

2021:01:08-00:00:01 ictrz-fw-01-1 postgres[11853]: [3-1] FATAL: role "smtp" does not exist
2021:01:08-00:00:01 ictrz-fw-01-1 postgres[11855]: [3-1] FATAL: role "smtp" does not exist
2021:01:08-00:00:01 ictrz-fw-01-1 postgres[11865]: [3-1] FATAL: role "smtp" does not exist

2021:01:08-00:00:01 ictrz-fw-01-1 postgres[11877]: [3-1] FATAL: role "smtp" does not exist
2021:01:08-00:00:01 ictrz-fw-01-1 postgres[11879]: [3-1] FATAL: role "smtp" does not exist

I assume that the database is corrupt and thus the disks are heavily in use. could that be the root cause?
