Just updated a single client from 1.6.3 to 1.6.4.2. The documentation seems to indicate that an upgraded client should still be able to mount the file system from a non-upgraded MGSMDT. The documentation appears to be referring to a 1.4 to 1.6 upgrade but I made the leap that similar things would apply to 1.6.3 -> 1.6.4.2.
As I said, the servers are still running 1.6.3 and have not been touched. The client is upgraded to 1.6.4.2. When I try to mount the file system I get... Is the MGS specification correct? Is the filesystem name correct? If upgrading, is the copied client log valid? (see upgrade docs) I've double-checked the first two but I have no idea what the third item refers to. The docs doc about using tunefs to manually copy client config logs when upgrading an MGS/MDS but they seem to indicate that the only issue on the client one needs to worry about is the form of the mount command. In going from 1.6.3 to 1.6.4.2, that should not be an issue. Have I missed a step? Do I need to do something to tell the MGS/MDS that the client has been upgraded? Is there newer documentation for going from 1.6.3 to 1.6.4.2? I was hoping that I could just upgrade the software on the MGS/MDS and OSS (in that order) and restart? Is that not the case?
