Situation

System failed to boot with messages:

1. "Failed to run raid array"
2. cache_check is missing/not found

uname -a output:
Linux hostname 4.9.0-3-amd64 #1 SMP Debian 4.9.30-2+deb9u1 (2017-06-18) x86_64 GNU/Linux

Reason

Some kernel modules and binary files were missing in the boot image. They are related to lvmcache if there are LVs backed by dm-cache.
