Hi all,
I have a question that I have not been able to resolve on my own.
Say I have a group of servers running glusterfsd which serve files to
a frontend glusterfs server. I am not using AFR and using AFR is not
an option. If one of the backend glusterfsd servers should go down
and lose all of it's data, is it possible to generate a list of files
that are no longer available (being located on the "down'd" glusterfsd
server) in a simple way?
If you have namespace brick on another server, you can use that info
for list of missed files.
For example, in one server you can store data brick #1 and namespace #2,
another server will have data brick #2 and namespace #1.
Ok. But how would I determine if they were missing or not? Would I
have to try to "touch" each file represented in the namespace cache or
is there some "trick" to making that determination fairly quickly?
The servers will be holding TBytes of data so attempting to check the
status of each file would take some time.
Thanks,
Majied
