The warranty of the seagate disks of storage1 and db1 ends by the end of February.
The current quota of replacement (3 disks) for this year is already consumed so I think we will have to wait for the beginning of 2022 to proceed.

The disks to replaced :

db1:
sdb / wwn-0x5000c500a44ee887
(currently in the spare pool with another disk)

storage1:
sdh / wwn-0x5000c500a22eed6f
(currently active disk on the mirror-2 pool, it can be decommissioned and the second disk added to the spare pool)
