Disk status
The following information lists the possible values for disk status, and what they mean.
Disk status controls data placement and migration. Status changes as a result of a pending delete operation, or when the mmchdisk command is issued to allow file rebalancing or re-replicating prior to disk replacement or deletion.
- ready
- Normal status.
- suspended
- or
- to be emptied
- Indicates that data is to be migrated off this disk.
- being emptied
- Transitional status in effect while a disk deletion is pending.
- emptied
- Indicates that data is already migrated off this disk.
- replacing
- Transitional status in effect for old disk while replacement is pending.
- replacement
- Transitional status in effect for new disk while replacement is pending.
GPFS allocates space only on disks with a status of ready or replacement.
GPFS migrates data off disks with a status of being emptied, replacing, to be emptied, or suspended onto disks with a status of ready or replacement. During disk deletion or replacement, data is automatically migrated as part of the operation. Issue the mmrestripefs command to initiate data migration from a suspended disk.
