Repair disk updating boot support partitions

If the partitioning scheme is not specified, then an appropriate one for the current machine is chosen. Times is the optional (defaults to 1) number of times to write random information. In either case, in order to be useful again, randomized wholedisks will need to be partitioned, or randomized partitions will need to be erased (newfs'd), e.g. If you desire a more sophisticated erase algorithm or if you need to erase only free space not in use for files, use the secure Erase verb.

Erase, using a secure method, either a whole-disk (including any and all partitions), or, only the free space (not in use for files) on a currently-mounted volume.

until interrupted with a signal (For example typing Control-C).

For debugging information, such as the monitoring of applications dissenting (attempting to deny) activities for disks for which they have registered an interest, use the logging features of the diskarbitrationd /usr/sbin/Diskutil verifydisk disk0 Started partition map verification on disk0 Checking prerequisites Checking the partition list Checking the partition map size Checking for an EFI system partition Checking the EFI system partition's size Checking the EFI system partition's file system Checking the EFI system partition's folder content Checking all HFS data partition loader spaces Volume Photos on disk0s5 has 0 bytes of trailing loader space and it needs 134,217,728 bytes Problems were found with the partition map which might prevent booting Error: -69765: Partition map needs repair because a data partition needs loader spacesudo diskutil repair Volume /Volumes/DGERMAN_2GB Password: Started file system repair on disk2s1 DGERMAN_2GB Checking file system ** disk2s1 ** Phase 1 - Preparing FAT ** Phase 2 - Checking Directories ** Phase 3 - Checking for Orphan Clusters 106 files, 1783744 Ki B free (55742 clusters) Volume repair complete Updating boot support partitions for the volume as required Finished file system repair on disk2s1 DGERMAN_2GB Started file system repair on disk0s9 Recovery_Mavericks Repairing file system Checking non-journaled HFS Plus Volume Invalid B-tree node size The volume could not be verified completely File system check exit code is 8 Updating boot support partitions for the volume as required Error: -69845: File system verify or repair failed Underlying error: 8: POSIX reports: Exec format error causes the creation of a 512MB Apple_Journal partition out of journal Device and an HFS partition will be created out of the remaining space if available; journal Device must be a partition. When ownership is enabled, the Owner and Group ID settings that exist on the disk are taken into account for determining access, and exact settings are written to the disk as FSOs are created.

Old disks are removed live, the RAID volume does not need to be unmounted.

If you need to erase all contents of a partition but not its hosting whole-disk, use the zero Disk or random Disk verbs.

Level : Only the "mirror" type increases fault-tolerance.

Adding a hot spare to a mirror will enable autorebuilding for that mirror. Adding a new member to a concatenated RAID set appends the member and expands the RAID volume.

Remove a member or spare from an existing RAID set.
