Rebalance is Stucked after 1.8.1 upgrade
Wed, 08/01/2012 - 12:22
Hello,
We have cluster (10 nodes) with 1.8.0 over Windows x64. We wish to upgrade to 1.8.1
I have tried several times to rebalance, also tried to upgrade or do a fresh install in one node, but keeps the same.
The rebalance does not fails, it simply gets stucked and there is no progress after 74.1%.
On the CLI I can keep seeying the dots "." coming throug and the status is "u running".
Nothing happens. When I install 1.8.0, rebalance is completed ok.
There are no errors.
Unfortunatelly we cannot turn off the cluster to do a offline upgrade. We need to be done node by node in online mode.
Any help is appreciated.
Well, I could upgrade all cluster members to 1.8.1.
I get the 74.1% stuck when at least one 1.8.0 member exists at the cluster as member.
I could think (stats proved that) the 74.1% was in fact a kind of 100%.
So I was upgrading every member. When I upgraded all of them, the rebalance got 100% again.
