Volumes can be in one of four states—online, offline, restricted, or quiesced. In addition, they can show one or more status values, depending on how they are configured and the health of their disks.
You can determine a volume's current state and status by using the vol status command.
The following table displays the possible states for volumes.
| State | Description |
|---|---|
| online | Read and write access to this volume is allowed. |
| restricted | Some operations, such as parity reconstruction, are allowed, but data access is not allowed. |
| offline | No access to the volume is allowed. |
| quiesced | The volume is in the final stages of a move. Data access is not allowed, and many volume, qtree, and quota management operations are temporarily unavailable. |
The following table displays the possible status values for volumes.
| Status | Description |
|---|---|
| access denied | The origin system is not allowing access. (FlexCache volumes only.) |
| connecting | The caching system is trying to connect to the origin system. (FlexCache volumes only.) |
| copying | The volume is currently the target of an active vol copy or snapmirror operation. |
| degraded | The volume's containing aggregate contains at least one degraded RAID group that is not being reconstructed after single disk failure. |
| double degraded | The volume's containing aggregate contains at least one degraded RAID-DP group that is not being reconstructed after double disk failure. |
| flex | The volume is a FlexVol volume. |
| flexcache | The volume is a FlexCache volume. |
| foreign | Disks used by the volume's containing aggregate were moved to the current storage system from another storage system. |
| growing | Disks are being added to the volume's containing aggregate. |
| initializing | The volume's containing aggregate is being initialized. |
| invalid | The volume does not contain a valid file system. |
| ironing | A WAFL consistency check is being performed on the volume's containing aggregate. |
| lang mismatch | The language setting of the origin volume was changed since the caching volume was created. (FlexCache volumes only.) |
| mirror degraded | The volume's containing aggregate is mirrored and one of its plexes is offline or resynchronizing. |
| mirrored | The volume's containing aggregate is mirrored. |
| needs check | A WAFL consistency check needs to be performed on the volume's containing aggregate. |
| out-of-date | The volume's containing aggregate is mirrored and needs to be resynchronized. |
| partial | At least one disk was found for the volume's containing aggregate, but two or more disks are missing. |
| raid0 | The volume's containing aggregate consists of RAID0 (no parity) groups (array LUNs only). |
| raid4 | The volume's containing aggregate consists of RAID4 groups. |
| raid_dp | The volume's containing aggregate consists of RAID-DP groups. |
| reconstruct | At least one RAID group in the volume's containing aggregate is being reconstructed. |
| rem vol changed | The origin volume was deleted and re-created with the same name. (FlexCache volumes only.) |
| rem vol unavail | The origin volume is offline or has been deleted. (FlexCache volumes only.) |
| remote nvram err | The origin system is experiencing problems with its NVRAM. (FlexCache volumes only.) |
| resyncing | One of the plexes of the volume's containing mirrored aggregate is being resynchronized. |
| snapmirrored | The volume is in a SnapMirror relationship with another volume. |
| trad | The volume is a traditional volume. |
| unrecoverable | The volume is a FlexVol volume that has been marked unrecoverable; if you have a volume in this state, you should contact technical support. |
| unsup remote vol | The origin system is running a version of Data ONTAP the does not support FlexCache volumes or is not compatible with the version running on the caching system. (FlexCache volumes only.) |
| verifying | RAID mirror verification is running on the volume's containing aggregate. |
| wafl inconsistent | The volume or its containing aggregate has been marked corrupted. If you have a volume in this state, you should contact technical support. |
