About the tool updates for cloud support
DCSCAN:
Dcscan downloads data container from the cloud. The default download path is <STORAGE>/tmp/DSID_#dsid, where #dsid is dependent on the cloud LSU DSID value. Different cloud storage providers have different DSID values. You do not need to know the DSID value, dcscan gets the DSID value automatically. The default download path can be modified in the contentrouter.cfg file using the DCSCANDownloadTmpPath field.
While using the dcscan tool to look at cloud data, -a option is disabled, because it downloads all data containers from cloud, it is an expensive operation. The -fixdo option is disabled as well, because dcscan only downloads data container from the cloud. Others operations are same as the local LSU.
SEEDUTIL:
Seedutil can be used for seeding a backup for a better deduplication rate. It creates links in the <destination client name> directory to all the backup files found in the path <client name>/<policy name> that have <backup ID> in their names. The user needs to know which DSID value the cloud LSU has used. That DSID value needs to be given to the seedutil, to let seedutil know which cloud LSU will seed a client. If you do a seeding for a local LSU, the default DSID is 2, you do not need to give the DSID value. Seedutil cannot seed across different DSIDs.
For example,/usr/openv/pdde/pdag/bin/seedutil -seed -sclient <source_client_name> -spolicy <source_policy_name> -dclient <destination_client_name> -dsid <dsid_value>.
CRCONTROL:
Using crcontrol - clouddsstat option to show cloud LSU datastore usage. DSID value needs to be given. As cloud storage has unlimited space, the size is hard-coded to 8 PB.
For example:
# /user/openv/pdde/pdcr/bin/crcontrol --clouddsstat <dsid_value> ************ Data Store statistics ************ Data storage Raw Size Used Avail Use% 8.0P 8.0P 80.9G 8.0P 0% Number of containers : 3275 Average container size : 26524635 bytes (25.30MB) Space allocated for containers : 86868179808 bytes (80.90GB) Reserved space : 0 bytes (0.00B) Reserved space percentage : 0.0%
CRSTATS:
Using crstats -cloud -dsid option to show the cloud LSU statistics. DSID value needs to be given. As cloud storage has unlimited space, the size is hard-coded to 8 PB.
For example:
#/usr/openv/pdde/pdcr/bin/crstats --cloud-dsid <dsid_value> Storage Pool Raw Size=9007199254740992Bytes Storage Pool Reserved Space=0Bytes Storage Pool Required Space=0Bytes Storage Pool Size=9007199254740992Bytes Storage Pool Used Space=86868179808Bytes Storage Pool Available Space=9007112386561184Bytes Catalog Logical Size=402826059439Bytes Catalog files Count=3726 Space Allocated For Containers=86868179808Bytes Deduplication Ratio=4.6
PDDECFG:
Using pddecfg to list all the cloud LSUs.
For example:
/usr/openv/pdde/pdcr/bin/pddecfg -a listcloudlsu dsid, lsuname, storageId, CachePath 3, S3Volume, amazon_1/cloud-bucket1/sub1, /msdp/data/ds_3 4, S3Volume2, amazon_1/cloud-bucket1/sub2, /msdp/data/ds_4
