Hi, I have some ageing hardware I'd like to remove. This includes the OSS and the OSTs connected to it.
So, as far as I understand, I need to deactivate the OSTs on the MDS with `lctl --device <devno> deactivate`, copy out all the objects from the deactivated OST with lfs_migrate and finally, permanently deactivate the OSTs on all the clients and MDS with `lctl conf_param <OST name>.osc.active=0`. Am I missing something, or is that it? Now for my real question: Once everything copied out, I'd like to permanently switch off and re-purpose the hardware. Do I need to do anything else, other than unmounting the OSTs and shutting down the OSS? As far as I can tell, the MDS still knows about the this OSS and OSTs, but will not try to use it. So will the removed OSS cause possible issues in future? If so, how do I fix it. With a --writeconf on MDS/OSS? All this will happen on a Lustre 1.8.5 system. Thanks in advance, Deon _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
