Increase the shadow copy storage area for the volume listed in the error event, or set the maximum size to “No limit.” To identify the volume listed in the event, run “mountvol” from a command prompt
; below the usage information will be a list of volume GUIDs and their associated mount points, if any.This size of the shadow storage area can be changed in the Shadow Copies utility, or from the command line.Note:
By default, each volume stores its own shadow copy. For example, a shadow copy of a CSV mapped to C:\ClusterStorage\Volume8 would also be stored on C:\ClusterStorage\Volume8. Do not change the location of the shadow copy storage area on a Hyper-V host server.
To access the utility, right click any volume and choose Configure Shadow Copies. In the Shadow Copies utility:
Shadow Copies Utility
- Select the volume with insufficient space;
- Click Settings…
- In the “Maximum size” box, either increase the limit, or choose “No limit”.
A limit at least 20% of the total volume size may be needed on busy servers.
All commands below should be run from an administrator command prompt.
Use vssadmin list shadowstorage
to view existing shadow storage associations. If no association exists for any volume, the command response will be “No items found that satisfy the query.”
If no association is listed for the volume, run vssadmin add shadowstorage
to set the size of the shadow storage area. For example, on a 1 TB volume labeled D:vssadmin add shadowstorage /for=D: /on=D: /maxsize=200GB
If a shadow storage association already exists, run vssadmin resize shadowstorage
to set the size of the shadow storage area. For example, on a 1 TB volume labeled D:vssadmin resize shadowstorage /for=D: /on=D: /maxsize=200GBThe /maxsize parameter is not optional, but can be set as /maxsize=UNBOUNDED
