Environment
VMware vCenter Converter Standalone 6.6
VMware vCenter Converter Standalone 6.4
VMware vCenter Converter Standalone 6.3
Cause
This thumbprint error is reported When converter connects to a new source, it does not know anything about its thumbprint, emptyThumbprint in the logs reported due to unavailability of thumbprint. Since it does not match the host thumbprint, an error is generated and the host thumbprint is returned.
Issue is with below error:
No disks for volume with id '/dev/rhel/var' and label ''
This is known issue with standalone converter which is documented in release notes.
When the source machine has more than one mount point, you receive the following error message: "Unable to query the live Linux source machine"
Converter expects each source file system to have a unique mount point. Having more than one mount point per file system breaks the analysis of volumes and partitions.
Resolution
To identify multiple mountpoints for same device,
No disks for volume with id '/dev/rhel/var' and label ''
Above error will convey that which device we need to consider for multiple mountpoints.
review vmware-converter-worker.log file for multiple mountpoint details.
--> <volume mountPoint="/var" blockSizeInBytes="4096" capacityInBlocks="5230080" blocksFree="4493612" blocksUsed="736468" devicePath="/dev/rhel/var" fileSystemType="xfs" isBootVolume="false" label="">
--> <volume mountPoint="/opt/sentinelone/rpm_mount" blockSizeInBytes="4096" capacityInBlocks="5230080" blocksFree="4493612" blocksUsed="736468" devicePath="/dev/rhel/var" fileSystemType="xfs" isBootVolume="false" label="">
Here, for dev/rhel/var, we had 2 mountpoints /var and /opt/sentinelone/rpm_mount.
As per your configuration, names and devices can be different.
To resolve this issue, unmount the one which is used for other services. e.g. here is /opt/sentinelone/rpm_mount.
Once unmounted view /proc/mount , you can also grep this file with mountpoint which we removed to confirm it is successfully unmounted.
Warning: Do not unmount the root (/) or boot (/boot) mount points. If any of them are mounted more than once, unmount the other mount point or points
