Configuring Data Scrubbing

Data scrubbing is the process of checking data chunks for durability and verifying their contents for readability and correctness. By default, Parallels Cloud Storage is set to examine two data chunks per minute on each chunk server in the cluster. If necessary, you can configure this number using the pstorage utility, for example:

# pstorage -c pcs1 set-config mds.wd.verify_chunks=3

This command sets the number of chunks to be examined on each chunk server in the pcs1 cluster to 3.
