Feature #11644
Updated by Tom Clegg over 7 years ago
Keepstore's role in the management part of the [[Keep storage tiers]] story.
* A "mounts" request (@GET /mounts@) should return information about all currently mounted volumes, e.g., @{"UUID":"zzzzz-aaaaa-aaaabbbbccccddd","Tier":1,"ReadOnly":false,"Replication":1,"DeviceID":"9febe660-c4e4-4db4-9f59-fbc9d559547c/keep"}@ ("DeviceID" is a string that can enable keep-balance to detect when multiple Keep mounts, possibly on multiple keepstore nodes, are using the same underlying storage device).
* A block-index request for a specific mount (@GET /mounts/zzzzz-aaaaa-aaaabbbbccccddd/blocks@) should return a list of blocks stored on that mount.
* An entry in a pull request may include a "MountUUID" field indicating which mount the new copy should be written to.
* An entry in a trash request may include a "MountUUID" field indicating which mount the block should be deleted from.
The new "/mounts" API is unrestricted. The other three APIs here, including the list of blocks for a specified mount, APIs, as before, are only available to system processes (i.e., require "data manager" token).
