my "/etc/crypttab" file content
cat /etc/crypttab
# <target name> <source device> <key file> <options>
luks-sdb1 /dev/sdb1 /sys/devices/virtual/dmi/id/product_uuid luks
luks-sdc1 /dev/sdc1 /sys/devices/virtual/dmi/id/product_uuid luks
"/dev/sdb1 /dev/sdc1" use keyfile "/sys/devices/virtual/dmi/id/product_uuid"
But report errors when rebooting
"/dev/mapper/luks-sdc1" successfully loaded, but /dev/mapper/luks-sdb1 failed
But after entering the system, manual "cryptdisks_start luks-sdb1" loading can succeed.Explain that configuration "/etc/crypttab" is not a problem!
