Hi João,
There isn't a straightforward way of tracking the crawl but as gluster uses
find and stat during crawl, one can run the following command,
# ps aux | grep find
If the output is of the form,
"root 1513 0.0 0.1 127224 2636 ? S 12:24 0.00
/usr/bin/find . -exec /usr/bin/stat {} \"
then it means that the crawl is still going on.
Thanks and Regards,
