Disks are partitions of an integrated storage data store that can be allocated to specific virtual servers. OnApp Storage disks are managed through the Control Panel > Storage menu. Disks for individual virtual servers are managed through the Control Panel > Cloud > Virtual Servers menu.
- When you exceed the NBD device path limit, you will see the following message in the UI failure log when starting a virtual server: No free devices available for the operation.
- Note that advanced disk sector format is not supported for Integrated Storage disks. Ensure that your disk drives support the 512-byte sector alignment before installing and using them with Integrated Storage.
- You cannot decrease the size of Integrated Storage data store disks.
- When you exceed the NBD device path limit, you will see the following message in the UI failure log when starting a virtual server: No free devices available for the operation.
Starting with OnApp 3.1.2, vDisks do not require 100% of parent virtual disk space reserved. The default snapshot value is now 10% of the virtual disk size or 1GB, whichever is larger. If disk size is less than 1GB, then snapshot reserve is equal to the disk size. You can change snapshot reservation on parent vDisk via the CLI tool from any compute resource:
onappstore snapreserve uuid=<VDISK UUID> reserve=<PERCENTAGE VALUE, e.g '20'>
CODE
The percentage value must be a multiple of 5 between 5 and 100.
