@cmuratori It seems to me that is basically just asking to have that array (which will all be on one SSD page) get wiped out together.
Does anyone out there understand the decision to store ZFS uberblocks in a _continuous_ array?

@cmuratori Why wouldn't you store uberblocks _strided_ across the drive instead? - Show replies

@cmuratori@nothings@won3d My guess: simpler allocation and location. The array & uberblocks should be bigger today due to SSDs etc, tho.Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori@nothings@won3d Eg apparently on 4k sector drives you only get 32 uberblocks, not 128, as they're padded to the sector size.Thanks. Twitter will use this to make your timeline better. UndoUndo

@cmuratori Technically, it's 4 continuous arrays per disk (2 and the beginning and 2 at the end). What would you prefer, and why? -
@cmuratori Ah, I see this discussion has already been beaten to death. Sorry for the noise! - Show replies
