I have purchased 2 used Exos 7E8 drives and an LSI 9211-8i HBA in IT Mode.

I have precleared them, with no apparent issues but when I try to format and mount into the array, I get a size X of data subvolume is too small, minimum 4096 blocks.

If I temporarily create a new pool and set the FS to XFS, they seem to format & mount fine.

My process was:

1. Pre-cleare drive

2. Stop array

3. Assign to Disk2

4. Set file system to XFS.

5. Start array

6. Check the box and click Format

The following are my logs:

That suggests they have an existing partition that is too small. Assuming no data there, got to Tools - New Config - Keep all - Apply, then back to main, click each disk and then "ERASE", now start the array and format.

Oops, I forgot about this post as I didn't have notifications on it...

I swapped SAS connector on my HBA and it worked fine.

I assume it's an issue with that.
