Hi Sahina! :)
Cool feature, and I think long-awaited by many users. I have a few comments:
1. In the "Add Bricks" dialog, it seems like the "IP Address" field
is a
list box - I presume the items contained there are all IP addresses
configured on the host's interfaces.
1. a. May I suggest that this contain network names instead of IP
addresses? Would be easier for users to think about things (they surely
remember the meaning of network names, not necessarily of IP addresses).
1. b. If I correctly understood the mock-up, then configuring a "Storage
Network" role only affects the default entry chosen in the list box. Is
it really worth the trouble of implementing this added role? It's quite
different than display/migration roles, which are used to determine what
IP address to use at a later time (i.e. not when configuring the host),
when a VM is run/migrated in the cluster.
If not for "Storage network" role, how would we default which network to
use. In fact, we are planning to remove the drop down to choose network
from the Add Brick UI, to avoid confusion and just use the network with
this role, if available - otherwise use the host address. (host_address
in vds_static)
Will update page accordingly
1. c. A word of warning: sometimes a host interface's IP address is
missing in the engine - this usually happens when they're configured for
the first time with DHCP, and the setup networks command returns before
an IP address is allocated (this can later be resolved by refreshing
host capabilities, there's a button for that). So when displaying items
in the list box, you should really check that an IP address exists for
each network.
2. "Storage Network": if you intend to keep this role in the feature (I
don't think it adds a lot of functionality, see article 1b), it might be
better to call it "Gluster Network" - otherwise people using virt mode
might think this network is gonna be used to communicate with other
types of storage domains.
Could this network be reused for other storage needs also. If not, we
can rename it "gluster network"
Yours, Lior.
