You should be able to resize the SR and re-scan and XenServer see the new allocated space.

I'm mostly iSCSI and do this often, not so much on NFS, but I would expect it to do the same.

If your description has your size in it you should edit that to reflect the new true size, but yes,

it should work.

is this still the way to go? just resize the NFS storage and rescan the SR? With all VMs still online.


Citrix has a bit of a different suggestion here: https://support.citrix.com/article/CTX120865


2.When its underlying Network File Share (NFS) volume is expanded, an NFS storage repository can be resized by simply detaching and then repair/re-attaching the SR.


In the 8.2 Documentation it says - regarding LUNs - just rescan: https://docs.citrix.com/en-us/citrix-hypervisor/storage/manage.html#live-lun-expansion


I'm bit scared as our current SR is hosting +-40 VMs.

Thanks for feedback . Götz

I deal mainly with LUN's so yes, if a rescan of NFS storage won't pick up the extra added space then detach/reattach. This will require either moving 

all of your storage to another SR or shutting down all of the VM's.  Instead of increasing the size of a NFS SR I would just add another one.

Hi Alan,


thanks for your feedback. To be more precise: I don't have in the current setup the option to add a second NFS SR. and moving +- 8 TB of VDs should be the last option as well.


So shutting down all VMs might be the needed option if the extra added space is not recognised.


May be someone has done tat recently on NFS?


Regards . Götz
