Hi,
I have a quite rare problem of lost data in Riak 2.0 beta1. I can hardly
replicate it but when it happens it looks like this order of operations:
(All operations are using bucket types).
1. write some data (KEY1) - ok
2. read that data (KEY1) - ok
3. message appears in riak console.log:
2014-05-21 08:15:03.328 [info]
<0.15793.157>@riak_kv_exchange_fsm:key_exchange:256 Repaired 1 keys during
active anti-entropy exchange of
{1450083655789255239155218544960687058564870569984,3} between {0,'
riak@10.0.1.1'} and {1450083655789255239155218544960687058564870569984,'
riak@10.0.1.3'}
4. read data (KEY1) - ok
5. write new data (KEY1) - ok
6. read data (KEY1) - no such key
All happens within 10-20 seconds.
Can someone give any hint on this?
Running riak2.0.0_beta1 on Ubuntu 14.04
Bucket type:
{"props":{"backend":"fs_chunks","allow_mult":"false"}}
fs_chunks backend:
{<<"fs_chunks">>, riak_kv_bitcask_backend, [
{data_root, "/var/lib/riak/fs_chunks"}
]}
Thanks!
