Hello Giuseppe, ISW metadata blocks_per_member (dev->vol.map.blocks_per_member) shall contain journaling space on the RAID member device, while r->sectors shall contain data space only. During RAID device configuration in metadata the journaling space is added to blocks_per_member: map->blocks_per_member = (map->blocks_per_strip * map->num_data_stripes) * div + RAID_DS_JOURNAL; Could you please provide ISW native metadata output from dmraid -n and device mapper mapping (dmsetup table and status) and dmraid array configuration (dmraid -C and dmraid -s)? Do you see "%s: zero sectors on %s"? If not, possibly there is an overflow and the reason might be in blocks_per_member configuration.
