Size Of Available Shrink Space
Check the properties of the VMDK through the web management, when you edit it, look next to the disk2. Depends on the server, if this is SQL, Exchange etc. You may need to rename the new disk to the same letter, but ensure you have good backups first. If this is your C drive, see option 33.
Solutions to Size of Available Shrink Space in MB 0 When shrink volume is 0, you can try to remove the unremovable files to increase available shrink space. However, the question is that it is hard to exactly find the file that stops you from shrinking C drive. The database file itself won't shrink, but if you were to move another 5Gb mailbox to that database, it wouldn't necessarily grow either, because it had 10Gb of “available new mailbox space” to place that data into. So in the “Enter the amount of space to shrink in MB” box I entered a value of 204800 (200GB = 200 x 1024 or 204800), for a 100GB partition the value would be 102400. Note that the “Size of available shrink space in MB” is the maximum amount the Windows 7 partition can be reduced.
Virtual to virtual, use the VMware standalone convertor to clone the machine and change settings during the move, you need different storage to do this and the machine will be down for the duration4. Move it from Lun1 to Lun2, I assume you are not very skilled in VMware if you don't know what Storage migration is.Disk size is the 1TB disk the VM sees, Physical space taken is dependant on thick or thin provisioning, thick will be the same size as the disk, thin will be only the used space out of the 1TB disk.
Size Of Available Shrink Space Too Small

We did this back in the 90's because of performance, however that's not the case anymore.Ethan6123 wrote:I've never personally had a bad experience with thin provisioning. If you had barely enough storage to fit your VMs it might be safer to go thick but thin is almost always better.

Thanks for the quick reply!!!1) How do i know if the disk is thin?2) Assuming it's thick, by creating another partition and moving the data to it, then removing the 1TB disk, will that affect the OS in any way? (i understand that i'm moving all the data, but just don't want after i move it, it fails to boot because some boot file isn't in the location it knew it to be and then i have to reinstall)3) What's V2V?4)Wanna elaborate a bit on 'Storage Migrate'? Just so we on the same page, can you also explain what you consider 'disk size' and 'physical space'?Thanks for the assistance once again, and sorry for so many questions!

» » » Here ALTER TABLE. SHRINK SPACE Command: Online Segment Shrink for Tables, LOBs and IOTsThe ALTER TABLE. SHRINK SPACE command was introduced in Oracle 10g to perform online segment shrinks for tables, LOBs and IOT overflow segments.Related articles.Shrink Space ExamplesHere are some simple examples of the ALTER TABLE. SHRINK SPACE command.- Enable row movement.ALTER TABLE scott.emp ENABLE ROW MOVEMENT;- Recover space and amend the high water mark (HWM).ALTER TABLE scott.emp SHRINK SPACE;- Recover space, but don't amend the high water mark (HWM).ALTER TABLE scott.emp SHRINK SPACE COMPACT;- Recover space for the object and all dependant objects.ALTER TABLE scott.emp SHRINK SPACE CASCADE;The COMPACT option allows the shrink operation to be broken into two stages. First the rows are moved using the COMPACT option but the high water mark (HWM) is not adjusted so no parsed SQL statements are invalidated. The HWM can be adjusted at a later date by reissuing the statement without the COMPACT option. At this point any dependent SQL statements will need to be re-parsed.Other shrink commands of interest are displayed below.- Shrink a LOB segment (basicfile only).ALTER TABLE tablename MODIFY LOB(lobcolumn) (SHRINK SPACE);ALTER TABLE tablename MODIFY LOB(lobcolumn) (SHRINK SPACE CASCADE);- Shrink an IOT overflow segment.ALTER TABLE iotname OVERFLOW SHRINK SPACE;There is more detail about this functionality below.
