Disabling Checksumming

Using checksumming, you can provide better reliability and integrity of all data in the cluster. When checksumming is enabled, Parallels Cloud Storage generates checksums each time some data in the cluster is modified. When this data is then read, the checksum is computed once more and compared with the already existing value.

By default, data checksumming is automatically enabled for all newly created chunk servers. If necessary, you can disable this functionality using the -S option when you set up a chunk server, for example:

# pstorage -c pcs1 make-cs -r /pstorage/pcs1-cs -j /ssd/pcs1/cs1 -s 30720 -S
