Would you know the correct MDS mount syntax (for OSTs and Clients) for an MDS failover?
For the OSSs , it does not appear to take the form: mkfs.lustre --ost --fsname=lustrefs --mgsnid=mds[1-2] /dev/sdb1 ** mount -t lustre /dev/sdb1 /mnt/lustre ,where mds1,mds2 are the mgsnids of the primary and failover MDSs. There is parsing error for mds[1-2] **, but knows of both mds1 and mds2 independently. For the clients, it does not appear to take the form: mount -t lustre mds[1-2]:/lustrefs /mnt/lustre ** Lustre cannot parse mds[1-2] ** , but knows of both mds1 and mds2 independently. As mentioned, I have tried comma separated names and colon separated names as well with no effect. The problem is with the mgsnid name structure. The ** only show where the errors occur. The MDS on its own fails over seamlessly and was not mentioned above (it also has the same fsname).

Please confirm that is the issue and the manual can be updated.
