From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hey,

I am planning to implement authenticated boot inspired from Pid Eins' blog. I'll be using pam mount for /home/user. I need to check integrity of all partitions.

I have been using luks+ext4 till now. I am ~~hesistant~~ hesitant to switch to zfs/btrfs, afraid I might fuck up. A while back I accidently purged '/' trying out timeshift which was my fault.

Should I use zfs/btrfs for /home/user? As for root, I'm considering luks+(zfs/btrfs) to be restorable to blank state.

Btrfs is good for small systems with 1-2 disks. ZFS is good for many disks and benefits heavily from ram. ZFS also has specially disks.

BTRFS is running just fine for my 8 disk home server.

That is not a recommended setup. Raid5 is not stable yet.

I never said anything about RAID5. I'm running RAID1.

Oh, I misremembered... It's only 7 disks in BTRFS RAID1.

I have:

  • 12 TB
  • 8 TB
  • 6 TB
  • 6 TB
  • 3 TB
  • 3 TB
  • 2 TB

For a combined total of 40 TB raw storage, which in RAID1 turns into 20 TB usable.
