Hello,
I am trying to use HAST between 2 FreeBSD-10.2 servers which are in 2
differents DC with a 100/100 mbit/s network and 14ms of ping between
them.
I used both (not at the same time) OpenVPN and a SSH Tunnel to transport
the data for security.
In both tries, hastctl tells me that the sync is complete, I can mount
it on one one, then I start to cp some files inside and then the primary
system hang after a few seconds when I do something disk related, only a
hard reboot can fix this. I can reproduce it anytime on both nodes. When
starting to write on the primary, the second node lose synchronization
and the primary hang like if it has a nfs mounted on something
disconnected (if you know that case).
I tried some hast.conf "tweaks" from the man to try to make it more "vpn
friendly" without success
resource essai {
replication async
compression lzf
on BBB {
local /home/shared
remote 10.8.0.6
metaflush off
}
on AAA {
local /home/shared
remote 10.8.0.1
metaflush off
}
}
/home/shared is a file made with dd with zeroes, maybe this is the
problem ?
Am I doing something wrong ?
Kind regards
