Really is happening what you told.... the partition concat/concat1 have the number 31, but in gstripe list it appears at position 21 position.... (see my first email) but the dump looks ok..... # gstripe dump concat/concat1 Metadata on concat/concat1: Magic string: GEOM::STRIPE Metadata version: 3 Device name: data Device ID: 494690382 Disk number: 31 Total number of disks: 32 Stripe size: 131072 Hardcoded provider: Another idea ?
