TrueNAS CORE

Is an OpenBSD distribution focused on NAS usage.

ZFS

Good newbie intro to ZFS

tl;dr by importance:

• Self-healink, no chkdsk anymore but you need to srub (= check checksum) montly
• Keep your pool >10% free space
• resilvering = in RAIDZ case and a drive failed, this is the initialization phase for the new drive
• Snapshot possible with no space overhead as CoW filesystem. This is applied for system config.
• Structuration
  1. vdev = group of disks
  2. pool = filesystem
  3. zvol = fixed sized raw volume or dataset = dynamically sized file volume
• Compression possible

Setup

Configure:

• Accounts
  • Users
    • root email
• System
  • Email
  • Alert Service > Email
• Task
  • SMART Task
    • Create short self test once a week, and long self test once a month (cf FreeNAS doc)
  • Periodic Snapshot
    • Create daily snapshot

Some guides:

• Windows SMB Share

Checklist to create a SMB share:

1. Create a dataset with Share Type = SMB
2. Assign ACL for a group (help here)
