Hive: Difference between revisions

Revision as of 22:32, 13 January 2025

Hive is a VM on Melange that runs my TrueNAS storage.

Pools

Pool	Capacity	Type	Drives
mine	43 TB	raidz	8TB ssd x7
safe	5.2 TB	raidz	1 TB ssd x7

NOTE that there is an eighth 8TB drive matching the mine array in Bluto. Harvest it from there if one of the 7 dies.

Mine Drives

Unfortunately I opted for Samsung SSD 879 QVO drives. The ONLY 8TB SSD option available, for a long time now.

Problems:

They are not designed to survive lots of reads/writes.
Because they are so big, it is very hard to maintain them, with scrubs taking hours, and resilvers BARELY able to complete after days.

Yep, they suck. And now I am stuck with them. So I will keep getting new ones and returning the bad ones, until I can move to MVME drives on a new PCIe card.

Hardware

LSI 8-drive SAS board passed through proxmox to hive as "PCI Device":

7 1 TB Crucial SSDs

Plugged in to SATA 1, 2, 3 and U.2 1, 2, 3, 4. NOTE: to get U.2 drives to be recognized by Melange ASUS mobo required a BIOS change:

Bios > advanced > onboard devices config > U.2 mode (bottom) > SATA (NOT PCI-E)
