"ZFS with a striped configuration can be more space-efficient compared to other setups like RAIDZ, as it does not require additional space for parity. However, the actual usable space will depend on the number of disks and the specific configuration used."
With this in mind, I started to migrate data from striped #zpool to #Raidz1
There was around 10TB of data to move. But after moving all that data, it took around 20TB on a two-drive raidz1. Some #BlackMagicFuckery

Started #zpool shinannigans. I'm switching from RAIDZ1 to Stripe storage type and want to remove two old, smaller drives. At the end, it should be one of those:
1. Same storage size, less power consumption, colder NAS, faster storage, and two empty drive bays.
2. Lost data, fire, and explosions.

Horror story in two lines:
```
Device: /dev/ada0, 24 Currently unreadable (pending) sectors.
Device: /dev/ada0, 24 Offline uncorrectable sectors.
```Y'all, if you have a #fileserver, always have a parity disk in the #raid volume. ALWAYS. They have saved my ass so many times. And, for the love of all that is righteous, make offline backups of your precious volumes.
Today is being spent on making my #TrueNAS server healthy again.

One of the ways I help avoid failures with raidz1 is by replacing HDD when they get to around 5 years old, or they start showing errors. Also, monthly scrubs helps ensure that the drives are getting fully utilized regularly which helps keep things healthy/accelerate detection of failures.
