VMware RDM lun out of space?
Posted on 2014-08-25
I'm having a hard time determining where my out of space issues on my RDM file server lun are coming from. Here are the results of df -h on my storage server.
RDM_vol = 7TB Total 7TB used
RDM_lun = 5TB occupied
File Server windows OS shows 1TB on that RDM attached lun
The mapping resides on a VMFS datastore with 50% free space. Everything is thin provisioned
So does the problem have to do with space reclamation? I didn't think that would be effective because fileservers always grow and never shrink thus the size should reflect the real size. Is there an alternative other then installing snapdrive?
Thanks again in advance
