If you have something unneeded then please delete it.

carme array is unfortunately 6 small, very old, SATA hard drives in software raid 10
(800GB of usable space total). No free hdd slots, so no way to easily get more storage space.
And one drive/cabling/hdd enclosure died (not sure, it's in remote location visited rarely),
so it's not even fully protected raid array:

Model Family:     Seagate Barracuda 7200.10
Device Model:     ST3320620AS
Serial Number:    5QF00AKL
Firmware Version: 3.AAC
User Capacity:    320,072,933,376 bytes [320 GB]


56024 power on hours :-) Over 6 years.
