The main problem seems to be that `spa_load_verify()` fails as can be seen below: $ sudo zdb -d -G dcenter zdb: can't open 'dcenter': I/O error ZFS_DBGMSG(zdb): spa_open_common: opening dcenter spa_load(dcenter): LOADING disk vdev '/dev/dsk/c4t11d0s0': best uberblock found for spa dcenter. txg 40824950 spa_load(dcenter): using uberblock with txg=40824950 spa_load(dcenter): UNLOADING spa_load(dcenter): RELOADING spa_load(dcenter): LOADING disk vdev '/dev/dsk/c3t10d0s0': best uberblock found for spa dcenter. txg 40824952 spa_load(dcenter): using uberblock with txg=40824952 spa_load(dcenter): FAILED: spa_load_verify failed [error=5] spa_load(dcenter): UNLOADING This change makes `spa_load_verify()` a dryrun when ran from `zdb`. This is done by creating a global flag in zfs and then setting it in `zdb`.
