Question

Using checksums to find corrputed documents in a volume

Administration Laserfiche

Updated June 1, 2015

asked on May 19, 2015

Is there a tool that exists that will crawl the volume and validate the checksums.

In the admin console on a given physical volume you can enable checksums. Then there is a right-click context menu option to “all tasks -> validate checksums”. I believe/hope there exists a tool to crawl the entire logical volume doing the same thing without having to manually validate each of the physical volumes individually.

Is anyone aware of a tool that can do this?

Thanks!

The volume consistency checker does not specifically use checksums, it compares general inconsistencies between the volume and the database, such as a file existing in one but not the other. It might also compare the size value. It is more a tool for tracking down missing files, but could serve as a starting point for trying to find corrupted images.

I believe Cristobal is referring to the Volume Consistency Checker, which can be accessed from the Support Site. This utility will cross-reference your database with your volumes and make sure there is nothing extra or missing. Check out this post for more information about how the utility behaves.

There is a utility from Laserfiche that is a volume checker. This will check the entries based on sql to the physical locations and create a report. It should also list missing document pages as well as extra files within each volume that you specify. I haven't been able to find it on the support site so you may have to request it from Laserfiche if you cannot find it either.

Thank you both for your responses. The goal is to try and find corrputed images. Is the Volume Consistancy Checker this the best/only way to do this?
