we have a raid 5 with 12 ssds plus 2 spares and one came to fail, now one of two of spares is active and a rebuild is happening:

  • in raid 5 data is striped in all disks or it is stored in each disk and the parity in all disk?

  • data of the failed disk will ve unavaible until the end of the rebuild?

  • The data is striped over all disks, with distributed parity.
  • All the data should be available during the recovery.
  • You shouldn't use RAID5 at all.
