      We had 2 OSS and 3 different OST crash with bitmap corrupted messages.

      Apr  3 18:38:16 nbp1-oss6 kernel: LDISKFS-fs error (device dm-42): ldiskfs_mb_check_ondisk_bitmap: on-disk bitmap for group 245659corrupted: 32768 blocks free in bitmap, 0 - in gd

      These errors were on 2 different backend RAID devices. Note worthy  items:
      1 .The filesystem was +90% full and 1/2 of the data was deleted.
      2. OSTs are formatted with " -E packed_meta_blocks=1 "
