I've understood that you don't see the problem any more with jewel,
but I didn't see any confirmation that 9ec6e7 is indeed the fix. Did
you run any more testing of hammer + 9ec6e7?
Oh, I updated the issues and not the ML. Yes, with hammer + that fix we no longer see the issue.
The fix is now pending for 0.94.10
Excellent.
So, I don't really understand how this corruption is triggered. Is it
something unique about the MSSQL workload that triggers it or is this
a general problem that's probably going on undetected by other RBD
use-cases?
It could affect other workloads as well. You'll definitely want to
upgrade once 0.94.10 is out.
JFYI, hammer backport now staged:
