[lustre-discuss] Make a backup and promote a new MGS/MGT

[Kieran Cavanaugh]

Greetings all,



Scenario is the following:


This is basically a storage refresh due to the age and supportability of the RAID controllers. The version of Lustre is......

well.....OLD ( Lustre 2.1.x)!!!  With no hopes of an upgrade since it wont be around for the long term.


At this point I have presented new storage to the existing MDS and OSSs, and have created a new filesystem on the existing

MDS/OSSs and have also provisioned a new MDS as well.

We are currently using RSYNC to migrate the user data to the old filesystem to the new one.

However, I want to migrate the MGT data to a new MGT device, and promote the new MGT, how would one go about completing this task?


Thanks,

  Kieran
