Current Status¶
Detailed Description¶
The current implementation of 'rados export/import' has some issues:- export/import speed is very slow
- export of large objects fails (e.g. big objects put via S3 into the cluster pool) due to limitation of extended attributes on the target filesystem
- depends on extended attributes support on local target filesystem
- direct export from cluster1 and re-import in cluster2 in one run (could be faster and needed in some cases)
- verification, checksums
Work items¶
Coding tasks¶
- export performance:
- random shuffle "ExportLocalFileWQ export_object_wq" before start export should increase the performance (dalgaaf: already implemented and tested, need to rebase and review)
- extended attributes:
- use different approach than extended attributes or at least add option to export without
- direct export/import
- add functions and options to export/import in one run
- verification/checksums
- ...
Build / release tasks¶
- Task 1
- Task 2
- Task 3
Documentation tasks¶
- Task 1
- Task 2
- Task 3
Deprecation tasks¶
- Support already exported pools to be imported again also with new implementation.
