I have a problem with changing store for my VM. My configuration is :
- two dell servers ( ESX1 and ESX2) with ESXi 4.1 HA ( cluster )
- dell MD3200i ( ISCSI ) storage with 17,6 Tb of space
- 17,6 Tb is divided 8 x 2 Tb + 1,6 Tb virtual disks via ISCSI
On 1,6 Tb virtual disk is created store for my VM-s . All VM-s are about 600 Gb. I have created another store to move VM physical to that store with migrate option. I can migrate all machines except the ones with this disk configuration :
I have three VM with 4 x 2 Tb disk inserted. Inside the VM I converted disk to dynamic disk and create stripe. So I have 8 Tb of disk space inside the virtual machine. VMDK file of VM is about 130 Gb. When I try to move to other datastore next button is greyed out with the message : insufficient disk space on datastore "xxxxx"
How can I change the datastore and what is the pocedure ?
I have enought space on new datastore.
Thanks for your help,
I'm not sure whether I understood the issue correctly. However, what I could think of is that the target datastore may not have been created with the required block size (8MB for virtual disks of up to ~2TB).
I have created new datastore with required block size ( 2048Mb, 8Mb ).
On ESXi i have 8 stores conected via ISCSI ( 8 difrent LUNs). One store is for virtual machines, other stores are for virtual disks ( 2 tb on each store ) and they are imported in virtual machine ( four virtual disks ( each is 2Tb ). Inside the virtual machine I have Server 2008 R2 64 Bit, disk is converted to dynamic and all disk are striped - total 8 Tb of disk space.
Do I have to remove virtual disk from VM settings, migrate to new datastore and then add virtual disks back ? If yes, can I loose data ?
I have resolve the problem. I removed VM from inventory, copy all files from one datastore to other datastore, add VM back to inventory in turn the VM on.
Thanks for help.
