:What I understand is that
:1) I am running hammer 'version 1'.
:2) I need to upgrade to hammer 'version2' for getting the latest stable.
You don't have to upgrade but it's a good idea. The target for
any mirror must be running a HAMMER version greater or equal to
the mirror source.
:1) can I run 'hammer version-upgrade /Backup1 4' directly or should I
:upgrade in sequence 1 > 2 > 3 > 4 ?
You can jump directly to 4. HAMMER will do the right thing.
:2) Should I kill the mirror-stream processes before upgrading the
:hameer file system on both /Backup1 and /Backup2.
:Thank you so much :-)
(I answered this in the previous posting but will include it here
I recommend killing them first, upgrading, then restarting the
The HAMMER FS version is for the whole filesystem, including all
of its PFSs. PFSs do not need to be individually upgraded.
