I might need to create another zpool. Or perhaps move a drives/zpool from one host to another.
In this post:
- FreeBSD 13.1
Background
I am combining two hosts (slocum and r720-01) into one new host (r730-01). I have been moving jails from those hosts. I have an ansible playbook for creating new entries in /etc/jail.conf.d/.
I thought I had the space calculations done right. Now I think I’m wrong.I’m already at 73% on the 5.8TB pool:
[r730-01 dvl ~] % zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT data01 5.81T 4.26T 1.56T - - 3% 73% 1.00x ONLINE - data02 1.73T 360G 1.38T - - 0% 20% 1.00x ONLINE - zroot 424G 2.14G 422G - - 0% 0% 1.00x ONLINE - [r730-01 dvl ~] %
I still have the FreshPorts development jails and the database server to migrate to this host:
[r720-01 dan ~] % zfs list | grep pg02 NAME USED AVAIL REFER MOUNTPOINT data01/pg02 541G 873G 88K none data01/pg02/dan 96K 873G 96K none data01/pg02/postgres 501G 873G 320G /jails/pg02/var/db/postgres data01/pg02/rsyncer 39.9G 873G 6.65G /jails/pg02/usr/home/rsyncer/backups tank_fast/dan_pg02 3.19G 571G 96K /jails/pg02/root/DUMPING tank_fast/jails/pg02 21.6G 571G 7.80G /jails/pg02
That’s about 560GB for for the database server.
Next, we have the FreshPorts websites/data:

That’s roughly 320G.
For a total of about 880GB
That will take both of the existing zpools to pretty close to 80%. I need more space.

I was trying to keep all jails in data01 and the data used by those jails in data01.
zpools in the old hosts
These are the zpools in slocum:
[slocum dan ~] % zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT nvd 930G 285G 645G - - 19% 30% 1.00x ONLINE - system 27.2T 4.51T 22.7T - - 24% 16% 1.00x ONLINE - tank_fast 398G 216G 182G - - 55% 54% 1.00x ONLINE - zroot 212G 33.3G 179G - - 25% 15% 1.00x ONLINE - [slocum dan ~] %
The system zpool is hard drives and I want to retire them from service (for reasons of noise, heat, and power).
These are the zpools in the other host r720-01:
[r720-01 dan ~] % zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT data01 1.45T 571G 917G - - 62% 38% 1.00x ONLINE - tank_fast 928G 328G 600G - - 51% 35% 1.00x ONLINE - zroot 72.5G 36.3G 36.2G - - 53% 50% 1.00x ONLINE -
There is 1.45TB there, in the form of 8 x 500GB SSDs, in mirrored pairs. That still won’t give much free space.
[r720-01 dan ~] % zpool status data01 pool: data01 state: ONLINE scan: scrub repaired 0B in 00:22:54 with 0 errors on Mon Feb 20 03:36:10 2023 config: NAME STATE READ WRITE CKSUM data01 ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 gpt/data1 ONLINE 0 0 0 gpt/data2 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 gpt/data3 ONLINE 0 0 0 gpt/data4 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 gpt/data5 ONLINE 0 0 0 gpt/data6 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 gpt/data7 ONLINE 0 0 0 gpt/data8 ONLINE 0 0 0 errors: No known data errors
If anything, I need to have free space to expand. Systems don’t generally use less data as time goes on. I’m hoping this system will be in use for another 3-6 years.
Shopping
I’d rather have raidz2 over mirrors. Just because that makes me feel safer.
I can get WD Blue SA510 1TB SSD 3D NAND SATA III 6Gb/s 2.5″ Internal Solid State Drive for $73 each. For $438 I’d have about 3TB of usable space (leaving 20% free) based on https://wintelguy.com/zfs-calc.pl.
I could double that space for $1020 by buying 6x Samsung 870 EVO 2TB SSD 3-bit MLC V-NAND SATA III 6Gb/s 2.5″ Internal Solid State Drive units (are those the ones with the recent firmware issues?).
Anyone want to fund me?
