This request is about the Content Transfer Tool, which can be improved for insufficient disk cases.
Use-case:
AMS instance with the S3 Data Store has been prepared for the very first initial extraction. Extraction started with about 400GB asset content. After about 1 hour, it failed. The logs forwarded to the Adobe Support.
They noticed the following statement on top of the output.log, see attached zip file :
Check Size results:
Migration Set size: 381.247 GB
Node store size: 2.202 GB
Data store size: 379.045 GB
Node count: 20,764,479
Free disk space (crx-quickstart dir): 24.398 GB
You do not have enough disk space in the crx-quickstart subdirectory of the source AEM instance to perform this extraction. You need to increase disk space by 51.486 GB or reduce the migration set size.
Current/Experienced Behavior:
CTT tried to run all extraction steps, until a failure occurred for the obvious root cause.
Improved/Expected Behavior:
The error gets logged with the prefix ERROR and the extraction halts immediately.
