Uma Maheswara Rao G commented on BOOKKEEPER-247:
------------------------------------------------
Thanks a lot Ivan,
Currently we are planing to detect the replication based on Bookie failures.
If one bookie shutdown or failed, then we will be able to detect with help of
auditor.
This code is checking each ledger for under-replication. If one bookie failed,
then all ledgers in that bookie should be replicated.
Use of this ledger checking would be only when some disks failed in bookie and
if still continue running the Bookie. That time, same bookie(partial disk
failures Bookie) can use this class and find the underreplicated ledgers?
If that is the case, worth editing the JIRA title as Detect under replication
of ledgers on bookie disk failures?
