Hello to everyone
Durable file handles allow a connection to an SMB server to survive a short
network outage. An ongoing IO will continue after the client reconnects to the
same server (maybe a difference smbd process if the CTDB status is always health
during the outage). When crossing nodes caused by virtual IP’s relocating,
durable handles will not work apparently.
CA feature in SMB3 works fine with cluster, but it is not accomplished yet and
it needs clients and servers support SMB3 simultaneously. Moreover, win7 do not
support SMB3 protocol.
Another approach is sharing durable handles data between samba nodes (through
CTDB or samba itself). This solution do not require client supporting SMB3
protocol and has good compatibility with win7/win8/win10. Has anyone been
working on it?
https://wiki.samba.org/index.php/Clustered_Samba#Clustered_Samba_Prototypes .
This page mentions three projects which maybe relate to this approach, but they
can not be opened.
Am I right about the descriptions above?
This wiki page mentions about “Durable handle cross-node”, but it just say “To
be filled”. https://wiki.samba.org/index.php/Samba3/SMB2#durable_handles
Thanks for explanations.
Regards,
weidong
