- Fixes an issue where cStor Volumes failed to provision if the
/var/openebs/directory was not editable by cStor pods like in the case of SuSE Platforms. - Fixes an issue where Jiva Volume - Target can mark a replica as offline if the replica takes longer than 30s to complete the sync/unmap IO.
- Fixes an issue with Jiva volume - space reclaim thread, that was erroring out with an exception if the replica is disconnected from the target.

- Fixed an issue causing cStor Volume Replica CRs to be stuck, when the OpenEBS namespace was being deleted.
- Fixed an issue where a newly added cStor Volume Replica may not be successfully registered with the cStor target, if the cStor tries to connect to Replica before the replica is completely initialized.
- Fixed an issue with Jiva Volumes where target can mark the Replica as Timed out on IO, even when the Replica might actually be processing the Sync IO.
- Fixed an issue with Jiva Volumes that would not allow for Replicas to re-connect with the Target, if the initial Registration failed to successfully process the hand-shake request.
- Fixed an issue with Jiva Volumes that would cause Target to restart when a send diagnostic command was received from the client

0.8.1 - Feb 23 2019#
Deprecation notice
This release has been deprecated. Please upgrade to the latest release. See upgrade instructions.
Change summary:
- Ephemeral Disk Support
- Enhanced the placement of cStor volume replica in a distributed randomly between the available pools.

kubectl getoutput of the CR. This feature requires K8s 1.11 or higher. - Fixed an issue where cStor volume causes timeout for iSCSI discovery command and can potentially trigger a K8s vulnerability that can bring down a node with high RAM usage.
