I've only had a couple of VMs in production for a few months using RAIDz-1 + compression, with 6 drives, 16k volblocksize and theory proved right, as the overhead was around 30%, comparing du -sh in the VMs with the amount of space used in the zpool. You've probably found this...
The metadata for the pool may be corrupted. If that is the cause your likely only resolution is a restore. My questions here are to prevent future problems. I've seen firmware corrupt drives too. That's why I want to see what your motherboard is, and firmware version too. Truenas Scale...
Originally, I wanted to use the case with all five drives independent, to allow TrueNAS to handle the RAID, but only ONE of the five drives showed inside of TrueNAS, while all five showed up when connected to a Windows box. So I configured my drive case to hardware RAID 5. When I ...

potentially with hundreds if not thousands of attached storage drives. ZFSpoolsthe available storage into zpools, made up of one or more virtual devices, referred to as vdevs, and manages all the devices as a single entity. A user can add more storage drives to the pool when the file sys...

How will this feature improve OpenZFS? Allows for better data protections even in the event that you don't have all the drives when creating the initial vdev/pool Additional context Given the recent work with raidz expanding, this feels like a natural progression of that work....
Traditionally hard drives had a sector size of 512 bytes; nowadays most drives come with a 4KiB sector size and some even with an 8KiB sector size (for example modern SSDs). When a device is added to a vdev (including at pool creation) ZFS will attempt to automatically detect the unde...
