hangc0276 opened a new issue #2529:
URL: https://github.com/apache/bookkeeper/issues/2529
**FEATURE REQUEST**
1. Please describe the feature you are requesting.
In current Bookkeeper implementation, when disk occurs IO error, eg, disk
readonly failure or disk sector failure, it will trigger bookie shutdown and
the bookie can't startup before the bad disk kicked off by admin.
In my production, we has 24 disks per node and the disks' failure rate is
high enough. If the bookie shutdown when occurs disk IO error, it will trigger
Bookkeeper cluster to re-replicate the lost data, which belongs to the shutdown
bookie. However the amount of data belongs to the bookie will be tens of TB,
which will cause Bookkeeper cluster busy and make it unstable.
2. Indicate the importance of this issue to you (blocker, must-have,
should-have, nice-to-have).
In my env, i should solved this problem before bring it to production.
3. Provide any additional detail on your proposed use case for this feature.
Do you have any ideas or plans to add this feature, or we can discuss the
feature design.
