mastgateway ecgstats
Returns the list of containers under rebuild from CGManager.
Syntax
WARNING
The mrconfig
command must be run under the supervision
of HPE support. mrconfig mastgateway ecgstats <cgid>
Parameters
Parameter | Description |
---|---|
cgid |
The Container Gateway ID from which the containers under rebuild must be retrieved. |
Output
For a given EC scheme k+m
, where k
is number of data
stripelets and m
is number of parity stripelets, the output fields are as
follows:
ContainerGroupId | Container Gateway (CG) ID from which the containers under rebuild are retrieved. |
numStripes |
Total number of valid (v), invalid (i), and pre-allocated (pa) stripes minus the number of deleted (d) stripes. Calculated as: |
numValidStripes | Stripe that have at least k number of full stripelets. |
numStripesToRecover | Stripes that have unelected stripelet(s), or number of full or partial
stripelets less than k . |
numStripesInRebuild | Stripes that are being rebuilt. |
numDegradedStripes[0] | Stripes that can have no more failures. |
numDegradedStripes[1] | Stripes that can suffer at most m-1 failures. |
numMaxStripes | Maximum number of stripes in the CG. This value is calculated from the container size and the stripe size. |
numActivePreallocStripes | Number of actual pre-allocated stripes. |
numActiveAllocStripes | Number of allocated stripes in the CG. This value is taken from the pre-allocated list. |
numActiveDeleteStripes | Number of valid stripes for which stripelets have been deleted by an operation such as compaction, for example. |
numPreallocStripes | Maximum number of stripes that can be pre-allocated. Default Value: 32 |
activeBitmap | Number of containers that are up in the CG. |
pendingUpBitmap | Number of containers that are in the process of being brought up in the CG. |
containersInRebuild | Number of containers that are being rebuilt. |
