Lyuben Todorov updated CASSANDRA-5891:
--------------------------------------
Attachment: 5891.patch
Added a -no-snapshot parameter to the "nodetool scrub" command. When supplied,
the parameter tells scrub to skip snapshot creation and saves disk space:
The below is for the size of the var/lib/cassandra directory
./nodetool scrub with -no-snapshot: cassandra dir size before scrub: 4.1G,
after scrub 4.1G
./nodetool scrub (without -no-snapshot): cassandra dir size before scrub: 4.1G,
after scrub 7.1G
> Scrub disk footprint needs to be reduced

>
> Currently scrub creates a snapshot at the beginning of the scrub. This causes
> the disk used to be doubled after the scrub.
> If the disk utilization is more than 50%, scrub wont work. It would be nice
> to have an overriding option to disable snapshot. Something like
> --no-snapshot.
