Grow partition past 2 tb on Windows Server 2003 iscsi
Posted on 2014-01-29
Hello to All,
I have a NAS device that I use as an iscsi target for one of my servers. I was running out of disk space on this server so I increased the LUN on the NAS form 2TB to 3TB with out any issues. I then tried to increase the partition on the server using disk management and it didn't even recognize the 3TB LUN. I started to research and found that since the disk has an MBR partition style, it can't grow past 2 TB. I can't convert it to GPT disk either because it is greyed out. I checked the event logs and the system log shows the following event:
Event ID: 1000
Cannot grow LUN Harddisk1: Extending the LDM partition failed.
I found that if I disconnect the iSCSI target using Microsoft's iSCSI initiator application and reboot then I have the option to convert the disk to a basic disk. If I select this option will it delete my partition? Also, if i convert it to a basic disk, will this then allow me to convert to GPT and grow the partition to the 3TB (which is the main goal)?
Can anyone suggest the best way to accomplish growing this partition?
Thanks in advanced everyone!
