Dear All, We have a Lustre server with MGS/MDT/OST in the same node: (IP: 192.168.60.151)
/dev/sda7 75374372 881520 69427728 2% /cfs/chome_mdt (MGS+MDT) /dev/sdb2 4842583272 4232667824 365744340 93% /cfs/chome_ost2 (OST1) /dev/sdc1 4841978664 806638400 3791199640 18% /cfs/chome_ost3 (OST2) where OST1 and OST2 are the external storage. Now we are going to separate OST1 and OST2 to other servers, and let the one 192.168.60.151 to provide only MGS+MDT. That means, the corresponding IP address of OST1 and OST2 will change. How do we make the change ? Could we just run (after shutting down the Lustre file system): lctl --writeconf <device> for all the MGS/MDT/OST, then switch OST1 and OST2 to another server, and then remount the Lustre file system ? Another question: now we are migrating the data files in OST2 out to clean it up, and want to reformat it with ZFS backend. Is it possible to have a single OST server to host both ldiskfs benkend (i.e., OST1) and ZFS backend (i.e., OST2) ? Thanks very much, T.H.Hsieh _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
