We need to do a lot of shuffling to get labstore1004 and labstore1005 to their final state. The scratch partition does not need any of the backup or service guarantees as other shares. Labstore1003 is fairly well resourced and mostly idle.
/dev/mapper/srv-dumps ext4 44T 16T 28T 37% /srv/dumps
/dev/mapper/srv-dumps ext4 28T 16T 12T /dev/mapper/scratch ext4 5T
9T unallocated for future use in either case.

I propose allocating /dev/sde to misc workloads (mainly scratch at this point). Dumps is still fine for space and performance, and we split out the underlying disks for isolation.
