Release News 0.7.4

Release 0.7.4

October 16, 2007

New Features:

SmartReadController
A controller capable of restoring data from the dsNet from at least the IDA threshold number of Slicestors. This is helpful when there are unavailable Slicestors or when the data on available ones is corrupted. The SmartReadController can also deal with potentially different sets of revisions of a datasource. It determines which revisions it can restore, and which is the most recent. This controller makes use of a configurable policy to determine how it starts reads and how it tries further reads in case a server is down or contains corrupted slices.

Enhancements:

Logging configuration reloaded dynamically

  • dsNet server and target will automatically reload the log4j configurations while they are running.

Logging of package revision

  • The repository revision used to create the slice-store and block-device packages is logged when the dsNet server or target start.

Improved JavaDoc documentation

  • JavaDoc has been improved on the following packages:
    • org.cleversafe.config
    • org.cleversafe.serialization.custom
    • org.cleversafe.server
    • org.cleversafe.storage

Fixed bugs:

  • D-01222 Target and Slicestor connection do not get re-established
  • D-01224 If Slicestors are down, initiator can not talk to target 
  • D-01228 Descriptor File is provided with 16x17 num-slices x threshold - Vault gets created successfully but initiator can not talk to target 
  • D-01233 NullPointerException when grid-config.xml not specifed 
  • D-01241 RemoteSliceStore synchronization issues 
  • D-01183 VaultFileResolver can't override default with property value 
  • D-01250 Error copying large files 
  • D-01262 dsgrid-create-vault hangs on connection exceptions 
  • D-01265 "Unable to load properties" error should be more descriptive 
  • D-01266 wrapper-server.conf has multiple repeated library names. 
  • D-01269 Problem after connection restoration

Known bugs:

  • D-01261 Error Copying Large Files
    • This problem happens when the iSCSI target and initiator are running on the same machine. 
    • Workaround: Run target on a separate machine from the initiator.
