Description Carlos Mestre González 2014-07-31 11:45:18 UTC
Description of problem:
After extending for a second time a master storage domain the used size decreases by exactly 1 GB

Version-Release number of selected component (if applicable):
rhevm-3.4.1-0.28

How reproducible:
100%

Steps to Reproduce:
1. Have 1 DC Shared with 1 iscsi storage domain
2. Add disks/vms (doesn't matter if preallocated or thin or number) 
3. Extend master (used and total size are updated properly)
4. Extend master again with other LUN

Actual results:
Used size is shrink by 1 GB

Expected results:
Used size is the same

Additional info:
* Importad: extend the storage domain a third time update the used value to the proper one
* This doesn't happen in 3.5

This is one run with values (Total here is available + used):

1st extend: domain iscsi_0. Allocated: 10737418240 Total: 213674622976 Used: 8589934592
2nd extend: domain iscsi_0. Allocated: 10737418240 Total: 266287972352 Used: 7516192768
               Used size for iscsi_0 is 7516192768, before extend was 8589934592
3rd extend: domain iscsi_0. Allocated: 10737418240 Total: 319975063552 Used: 8589934592
               Used size for iscsi_0 is 8589934592, before extend was 7516192768
