    Description

      This ticket relates to transfer of idmap information between the server nodes. The goal is that the MGS stores the UID/GID maps in an index (similar to how quota is storing the master quota files) and these are transferred to the other servers to keep the mappings consistent.

            Hi Peter,

            It would be best if it did, but it's not mandatory. Without that patch, if the MGS goes away, the OSSes and MDSes will not be able to load the nodemap configuration if they get restarted.

            Thanks,
            Kit

            It looks like there is still one patch - http://review.whamcloud.com/#/c/17503/ - being tracked under this ticket. Does that need to land for 2.9?
