Output Fields
Field |
Description |
---|---|
cid |
Container ID |
volid |
Volume ID of the volume to which this container belongs. |
sp | Storage pool to which this container belongs. For
example: SP2:/dev/sde Here, SP2 is the name of the storage pool. /dev/sde is the disk on which the container resides. |
spid | Storage pool ID |
prev | Pointer to the previous snapshot cid or rw cid (for a clone container), in a snapshot chain. |
next | Pointer to the next snapshot cid or rw cid (for a clone container), in a snapshot chain. |
issnap | Indicates whether container is a snapshot or not, in a snapshot chain.
|
isclone |
Indicates whether this container is a clone container created as part of the resync operation.
|
deleteinprog | Indicates whether this container is marked for deletion.
|
fixedbyfsck |
Indicates whether fsck was run on this container to fix any data or metadata errors.
|
stale | Indicates whether the current cid is a stale cid or not. Container is
marked as stale when it is yet to be processed for cleanup.
|
querycldb | Indicates whether the container is awaiting its role from CLDB at the
time of bringing up a cluster.
|
resyncinprog | Indicates if the container is resyncing from another container in the
container chain.
|
shared |
Indicates whether the container is hosting any shared data. The value is the number of shared data blocks (each of size 8K). |
owned |
Indicates the number of data blocks (each of size 8K) that the container owns. |
logical | Indicates the number of logical data blocks (each of size 8K) that are present in the container. |
snapusage | Indicates the number of container blocks (each of size 8K) that are used for storing snapshot data. |
snapusageupdated | Internal field. |
ismirror | Indicates if this container is of a mirror volume or not. 0 - Is not of a mirror volume 1- Is of a mirror volume |
isrwmirrorcapable | Indicates if the container belongs to a mirror volume, and if the volume
can be converted to a rw volume, in case the primary volume goes down.
|
role |
Role of the container, in the container chain.
|
totalInodes |
Indicates the total number of inodes that can be created on the container. |
freeInodes | Indicated the number of inodes that are still available to be used. |
dare |
Indicates whether the container belongs to a volume that is dare-enabled or not.
|
istiered | Indicates whether the container belongs to a tiered (either cold-tiered
or EC enabled) volume.
|
numtotalblocks | Applicable only for tiered volumes, this parameter indicates the total number of data blocks present in the container. |
numpurgedblocks |
Applicable only for tiered volumes, this parameter indicates the number of data blocks that are offloaded and not locally present. This value decreases in case of recalls. |
numoffloadedblocks |
Applicable only for tiered volumes, this parameter indicates the number of data blocks that are off-loaded to the tier. |
maxUniq | Internal field. |
isResyncSnapshot | Indicates whether the container belongs to the resync snapshot.
|
snapId | Indicates the snapshot ID to which this container belongs, if the ID is a snap cid. |
port | Indicates the MFS port number used by the container. |
