[Gluster-users] libgfapi management functions

[Prasad, Nirmal]

Thanks for the response – the one functionality or hook I’m looking for is a notification for brick failure – presently the process involves checking the volume status to see if a certain brick goes offline.

When a brick fails, would want to start a timer and replace the brick if it does not come up automatically – alternatively if gluster allowed specifying “hot-stand-bys” to replace with at a certain timeout (eg. 1 minute or a replica threshold)  it would work.

Thanks
Regards
Nirmal

Hi,

Is there any plan or interest in getting the management functions added to gfapi? – looks pretty much like the client library functions could be added.

eg. the present libgfapi has glfs_mgmt.c with a few rpc messages exchanged with glusterd

https://github.com/gluster/glusterfs/blob/master/api/src/glfs-mgmt.c

Any interest or plans to have more operations exposed (especially brick status change notifications to be propagated to applications)?  I’m wondering if gluster cli could be built on this library – it would involve taking the functionality that exists in the cli into a library and separating out the console interactions.

Thanks

Hi Nirmal,

The file glfs_mgmt.c has only those functions which are required by the client stack of glusterfs to interact with
glusterd. The management here refers to interaction of the process/library with the glusterfs management daemon which is glusterd for its own purpose.

GFAPI is currently intended to be used only as a interface/api to the file glusterfs filesystem and not for management operations.

Do you have a specific requirement which would require such a feature from GFAPI?

There are other projects being developed to provide API for management operations like
