Hi Toby,
I'm sure someone from Basho will answer soon, I just pointed you to the
"release notes" direction. I have only overlooked the release notes
until we decide to migrate to 1.4.0 when is final (Right now on rc1)
HTH,
Guido.

Thanks Guido.
Looks like we've upgraded to 1.4.0 completely now and the cluster is back up.
I'm not sure of the exact root cause, but what we were seeing was that too many
nodes went down for the ring to be healthy, and then when nodes were restarted
they waited for the ring to appear for a while, and then exited (or crashed)
automatically.
I *think* this is because after the package was upgraded, the Riak service
didn't restart after the upgrade -- and our automated system to catch that and
restart them wasn't kicking in quickly enough compared to the rate at which the
servers were being upgraded.
You mention in the release notes that the init scripts have been adjusted -
maybe that has something to do with it?
Cheers,
Toby

Known Issues
leveldb 1.3 to 1.4 conversion
The first execution of 1.4.0 leveldb using a 1.3.x or 1.2.x dataset will initiate an automatic conversion that could pause the
startup of each node by 3 to 7 minutes. The leveldb data in "level #1" is being adjusted such that "level #1"
can operate as an overlapped data level instead of as a sorted data level. The conversion is simply the reduction of the number
of files in "level #1" to being less than eight via normal compaction of data from "level #1" into
"level #2". This is a one time conversion.
HTH,
Guido.

Hi,
some of our nodes upgraded to Riak 1.4.0, and are now refusing to start and
join the cluster.
Is there documentation on the upgrade path from 1.3.2 to 1.4.0? It appears we
have accidentally begun this journey, and I don't know if it's easier to go
back or forwards now..
PS. It would have been pleasant to receive a warning about the new version on
the mailing list!
Thanks,
Toby
