There are no running tasks, but there is a large amount of used space on the vRanger VA. This can be checked by loggin on to the VA and typing df -h.
At the end of each replication, the .vzundo files should be removed from the scratch disk. If a replication ends improperly, such as by rebooting the vRanger server or restarting the vRanger service, the file remains on the disk.
When logged onto the VA, enter the command find /scratch/sdb -name *.vzundo | xargs /bin/rm -f. This will search the scratch disk for any .vzundo files and remove them. Do not perform this operation when a replication is in progress!
