I have multiple luns presented to a Windows 2008 R2 standard server via iSCSi. Data has been written and deleted successfully to these luns for months and the problem I have is a major differance in the available space between the OS and the lun / volumes within system manager v2.0.
For Example: Drive on server shows 1Tb free space / luns within system manager shows 1Tb free space / volume in system manager shows 200Gb free space. I need to resize this vol by -500Gb and I can't because it thinks there is only 200Gb free plus I'm cautious that the vol will go offline as the OS thinks it has buckets of space free!
2 snap shots created totalling 100Gb and the fractional reserve is set to 0% and no snap reserve (yet)
I have run a space reclaimer using snap manager but this only balances the sizes between OS and sys manager luns. ON TAP version 8.0.1 P4......any ideas or comments appreciated.
