Fixed In Version:
Doc Type: Known Issue
Doc Text:
Cause: As 'rebalance' and 'remove-brick' are data migration operations, triggered from inside the filesystem itself, the quota usage limits are not enforced properly during that time. Consequence: During the time of rebalance/remove-brick it appears that the quota usage limits could have been not enforced as there is a chance that limits can be crossed because of temporary file creations by these processes. Workaround (if any): None. Ignore quota while these process are running. Result: Peace of mind :-)

Description shylesh 2012-05-22 10:56:23 UTC 
Description of problem:
While rebalance or remove-brick is happening temporarily volume may violate quota limits.


In rebalance and remove-brick while migrating the data the file will not be truncated until it is completely written to the destionation, at this point in time there will be a chances of violating quota limits.

 suppose volume quota limit is 900MB and rebalancing a 500MB file, just before the completion of migration the total size might be 1GB but this will not be visible to the quota translator.
