2016??11??17?????????????? <[email protected]> ??????
Thanks for your reply ! I have many data folders such as data1,data2... and
this data folders contains some files. The data will be disable if one files
missed. I use distributed volume storage the data folders and the files of data
folder is distributed to all bricks. The all data folders will be disable if
one brick down.
Fully understand your situation. it's your application characteristic which
one file missing will bring the upper layer
application not work.So you want to make the impact of brick failure as small
as possible.
I think out the distributed replica volume,but disk utilization is less than
50% whth replica volume.I can put up with some data missing ,but I cann't
tolerate all data being disable. So,I want the data folder storage just one
brick,so that ,if one brick down , it has some data folder disable in this
brick and other data is well.
The capacity cost seems the tradeoff of high availability,if you can't bear
it.Two suggestions:
1. replace replica with EC to overcome the low disk usage while maybe bring
some performance issue.However I'm new to glusterfs and not very sure about the
EC implementation detail and the stableness.
2. let your application layer to do some work solve the disperse of the data
without glusterfs involving it.
Hope that is helpful for you.
