This article details how to use vhd-util to scan for Orphaned/Bad VHD Files.

Requirements

• CLI connection to XenServer host, preferably through an SSH client

• Basic CLI command usage (grep, less, tail)

• LVM, EXT, or NFS storage type

---

Instructions

Complete the following procedure:

1. Identify the SR that has a bad VHD using the SMlog. You will see errors regarding exception or scan errors with reference to a python script.

2. Run the vhd-util command.

• For LVM/iSCSI/HBA: vhd-util scan -f -m "VHD-*" -l VG_XenStorage-<UUID of SR> -p
• For NFS/EXT: vhd-util scan -f -c -p  -m /var/run/sr-mount/<sr-uuid>/*.vhd

3. Find the uuid of the VHD. You may see errors such as header/footer errors, missing parent, or corrupt. When identified, decide how best to resolve the scan error.
