### Please describe the problem.
|
|
|
|
The tahoe-lafs remote has no built-in way to perform the repair operation.
|
|
This results to data loss if expiration is enabled on the Tahoe grid.
|
|
|
|
For the current tahoe-lafs release (1.10.0), the only way storage space is freed
|
|
is via garbage collection. Garbage collection removes shares whose lease has expired.
|
|
Data loss will occur if leases are not periodically renewed via
|
|
"tahoe repair --add-lease WRITECAP".
|
|
|
|
The current implementation of the Tahoe remote in git-annex does not offer a way to
|
|
run lease renewal, and cannot be used on grids where GC is enabled. (GC is not enabled
|
|
in the default configuration, but on private grids it is a sensible option.)
|
|
|
|
One way renewal could be made easier to do is to add the uploaded files to a directory
|
|
in Tahoe, so that the leases could be easily updated if the directory writecap is known,
|
|
without needing to go through the full list of writecaps for each file stored.
|
|
|
|
### What steps will reproduce the problem?
|
|
|
|
1. Use tahoe remote on a tahoe grid where GC is enabled.
|
|
|
|
2. After GC expiration period, data loss ensues.
|
|
|
|
### What version of git-annex are you using? On what operating system?
|
|
|
|
Seems to affect current git master (as of 2014-08-24).
