Wish list : automatic rebuild with hot swap osd ?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I wonder if it's possible to add to ceph the ability to rebuild a new disk automatically freshly added to a slot in replacement of a failed osd
disk.

I imagine something like adding a flag on disks (identified by-path for example or a way to have a deterministic access to the device) to be
auto-reconfigured if detected with no data after the same slot was marked as failed. Only disks identified "by-path" with an auto-rebuild flag
activated, and previously marked as failed, can run the auto-reconfiguration.

I know it should take some time to find the best way to implement that feature to avoid zapping a disk with data but that would be great to
improve maintainability.

Thanks,
