Looks if disk is connected on power-up, but immediately removed. Controller failure?

btrfs RAID0 on partitions sd{2..5}. Recovering partition 4 and 5 most desired.

Partition 4 was "/", prefer to retrieve "/etc".

Partition 5 was "/home", prefer to retrieve as much as possible. Home directories were using Ubuntu's ecryptfs home directory encryption, unclear how to mount, but I have the key (user password) and otherwise partition 5 should be mountable once recovered and encrypted files visible.
