Rebuild Types

Unknown A pseudo value used if the type of operation is not recognized

Rebuilding Represents the operation where a degraded group is repaired

Erasing Represents the operation where the data contained in a group is purged

by writing to every sector of the RAID group

Writing Represents the operation where a specific data pattern is written to every

sector of the RAID group

Converting Represents the operation where data is shuffled around within a group

either because the group is being converted from one RAID level to

another, or thecapacity of a group is being expanded

Initializing or Advanced

Initializing

Represents the operation where new disks added to the group are

undergoing full initialization. This can happen either when the group is

created, migrated or expanded

Initializing or Express

Initializing

Represents the operation where the group undergoes a parity rebuild (if

applicable) for the new members added. This can happen either when

the group is created, migrated or expanded

Media Scanning Represents the operation where I/O is performed to each block on a

device to force the reallocation of bad sectors. All error correcting is

handled automatically by the device, and any errors detected will

increment the appropriate counters

Parity Verifying Represents the sector scan operation that also verifies the parity blocks

on a RAID group are correct. If errors are found, they are left

uncorrected, and the appropriate error counters are incremented

Parity Repairing Represents the parity scan operation that also attempts to fix any parity

errors that are encountered. Any errors detected will increment the

appropriate error counters

Recovery Rebuilding Represents the operation where an offline group is forced online prior to

rebuilding it
