Hey everyone,
I'm currently facing a bit of a conundrum with my ZFS pool setup, and I'm hoping that some of you knowledgeable folks out there can lend a hand. I have a ZFS pool with a mirror VDEV configuration (2 x 4TB), and I'm looking to expand it by adding a single drive (1 x 6TB). Here are the details:
Current Setup:
Mirror VDEV: Drive A (4TB) + Drive B (4TB)
Total Usable Capacity: 3.64TiB (mirrored)
Desired Expansion:
Add a new Drive C (1TB) to the existing pool
Reconfigure the mirror VDEV to include Drive C
Increase the usable capacity of the pool by configuring it to RAID1?
I understand that ZFS allows for expanding a pool by adding VDEVs, but since I have only one other drive, I need clarification.
I've done some research, but I couldn't find a definitive answer or a step-by-step guide for this specific scenario.
If any of you have experience with expanding ZFS pools in a similar way, I would greatly appreciate your guidance. Here are a few questions that I have:
Is it possible to expand a mirror VDEV with a single drive? I do see extend button in the UI. What does it do?
What is the recommended procedure for adding a single drive to an existing mirror VDEV?
Will the data from Drive A and Drive B be automatically rebalanced across the new Drive C?
Are there any precautions or best practices that I should be aware of before attempting this expansion?
I'm open to any suggestions, tips, or resources that you can provide. Your expertise will go a long way in helping me achieve a successful expansion of my ZFS pool. Thank you all in advance for your support!
My current pool is 80% full, and I want to keep the data, and I don't have any additional drive lying around, So deleting and recreating the pool would be very difficult.
