ZEVO ( not zfs ) beginners question

Post by rhinkligor » Wed Feb 20, 2013 3:46 am

Hey Guys,

So here is my setup:

I have a macbook with an HFS+ formatted SSD serving as boot Volume with parts of my home directory residing on it ( Library etc. ) encrypted using Filevault 2.

The Rest of my Data is on the 2nd 1TB HDD where the SuperDrive used to be.

Now i want to use ZFS on the 1TB HDD, and further plan on using:

CoreStorage to encrypt the zfs slice on the disk. Any Issues with that ?
Copies=2 for safety
Case Insensitivity would be a good idea ?

And further: Will i need to export the pool before rebooting ? I know zevo automatically imports...


Thanks and kind regards,

Core Storage encryption with ZEVO

Please see:


copies=2

See:


Case insensitivity

See:


If the hard disk drive is not Advanced Format, then choose a more appropriate value for ashift.

No :-)

… Data is on the 2nd 1TB HDD … i want to use ZFS on the 1TB HDD …


Alongside the solid state drive, I visualise only one hard disk drive in your MacBook.

Is there a second hard disk drive, external?

For performance, give an entire disk to ZEVO.

… parts of my home directory residing on …


For a home directory, please use:

  • no more than one file system
  • subdirectories (not separate file systems) at the expected paths.

It's probably you will experience some issues with cross-platform programs / tools. I was running non-sensitive setups since I bought my first Mac, but lately I had to solve som strange problems by moving scripts / development work between mac and linux for example.

It took me some time to realize why 1:1 moved copy of mysqld from macosx to linux is not starting (upper / lower mysql table names), why my project won't compile (because original author created two files in the same directory with names "RELASE" and "release"). So I'm avoiding this for future.

Anyhow case sensitivity is mixed on zevo and zfsonlinux as well so you can create the pool as insensitive and then create filesystems as you wish. You can't change after fs creation, but is not dependent on the pool (as for example ashift, maybe normalization)
