Description

The bucketfsd may in some scenarios hang indefinitely on one of the nodes, making the service unusable. When this happens, a log entry with the "RSYNC THREAD finishing" message is printed in the bucketfsd log but no corresponding “RSYNC THREAD finished” is ever printed, meaning the service is stuck.

Workaround

Restart the bucketfsd partition using coskillall:

coskillall bucketfsd-bfsdefault

There is one such partition per each BucketFS Service.

Fix

bucketfsd doesn’t hang in such situations and remains operational.
