Encrypted degraded RAID 1 on Debian Stretch

[questlinq]

Hello,

I'm having an issue with degraded raid 1 in encrypted mode on Debian Stretch. It happens only when I physically disconnect first or second HDD - after Debian fails to boot while showing the following message ..

cryptsetup (md0_crypt): lvm is not available

Did anyone of you had a similar issue and found a solution how to fix it?
