TODO

• move sassy and splat data to safe, remove them
• continue migration until we have 7 slots free (16 - 7 safe - 2 grim)
• add 7 new BIG ssds in new raidz array
• rinse and repeat

Overview

FreeNAS provides storage via Pools. A pool is a bunch of raw drives gathered and managed as a set. My pools are one of these:

• single drive: no FreeNAS advantage other than health checks
• raid1 pair: mirrored drives give normal write speeds, fast reads, single-fail redundancy, costs half of storage potential
• raid0 pair: striped drives gives fast writes, normal reads, no redundancy, no storage cost
• raid of multiple drives: FreeNAS optimization of read/write speed, redundancy, storage potential

The three levels of raid are:

• raidz: one drive is consumed just for parity (no data storage, ie you only get (n-1) storage total), and one drive can be lost without losing any data; fastest
• raidz2: two drives for parity, two can be lost
• raidz3: three drives for parity, three can be lost; slowest

Pools

• Drives

Pool	Capacity	Type	Drives
sassy	0.2 TB	single	250GB ssd
splat	3.6 TB	raid0	1.82 TB hdd x2
mack	0.9 TB	single	1 TB ssd
reservoir	2.7 TB	single	2.73 TB hdd
grim	7.2 TB	raid0	3.64 TB ssd x2
safe	6 TB	raidz	1 TB ssd x7

Datasets

Every pool should have one dataset. This is where we set the permissions, important for SAMBA access.

Dataset settings:

name #pool#-ds
share type SMB
user m
group m
ACL
 who everyone@
 type Allow
 Perm type Basic
 Perm Full control
 Flags type Basic
 Flags Inherit

Windows SMB Shares

Share each dataset as a Samba share under:

Sharing > Windows Shares (SMB)

Use the pool name for the share name.

Use the same ACL as for the dataset.

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)
