Subject: Re: [zfs] [developer] Re: [smartos-discuss] an interesting survey --
the zpool with most disks you have ever built
Hi Fred -
We don't use any cluster software. Our backup server is just a full copy of
our data and nothing more. So in the event of a failure of the master our
server clients don't automatically fail over or anything nifty like that. This
filer isn't customer facing, so in the event of a failure of the master there
is no customer impact. We use a slightly modified zrep to handle the
replication between the two.
thanks,
liam
[Fred]: zpool wiith 280 drives in production is pretty big! I think 2000 drives
were just in test. It is true that huge pools have lots of operation
challenges. I have met the similar sluggish issue caused by a
will-die disk. Just curious, what is the cluster software
implemented in

?
Thanks.
