I have a situation where someone had an older vSphere 4.x cluster. The VMs were hosted off of a iSCSI SAN controller to the nodes in the cluster. The volume was 260GB originally when I made it a few years back. Subsequently they have added enough VMs that they needed to expand. They expanded the LUN capacity to 3TB, but was never able to expand the partition. With VMFS3 this is an issue.
Seems if you epand the LUN, EVEN IF you NEVER expand the partition, your systems, if they unmount the volume can never mount it again.
This apparently went on for some time where over time more systems would not "access" the LUN.... and after a power outage, no system could then access the dozens of VMs.
Now I need to find a way to mount that 3TB iSCSI LUN, even if read only, long enough to mount the 260 of VMs off of it to NFS share i have ready.
Goal: map iSCSI LUN to Windows / Linux system. Mount the volume RO. Copy data to NFS export. Destroy and rebuild the data on new iSCI VMFS5 lun.
I can mount the LUN to CENTOS system and parted shows the 3TB LUN but primary partition only 260GB. So I see the data as expected. Now I tried to compile 'vmfs-tools-0.2.5" but get compiler errors. Nothing of any help or note. I tried ubuntu and CENTOS48 also and errors not much help.
Is their another, more simplistic way to get this accomplished?
Thanks,
