Hi Travis,
These binaries are hosted on Canonical servers and are only for Ubuntu. Until
the latest FireFly patch release 0.80.9, everything worked fine. I just tried
the hammer binaries, and they seem to be failing in loading up erasure coding
libraries.
I have now built my own binaries and I
Hi,
Does ceph typically use TCP or UDP or something else for data path for
connection to clients and inter OSD cluster traffic?
Thanks

To follow up on the original post,
Further digging indicates this is a problem with RBD image access and is
not related to NFS-RBD interaction as initially suspected. The nfsd is
simply hanging as a result of a hung request to the XFS file system
mounted on our RBD-NFS gateway.This hung XFS
Thanks a million for the feedback Christian!

I could do it in different terminals) without noticing any problems. Can

google is your friend, this comes up every month at least, if not more

rightly so).

Based on your feedback, I modified the CRUSH map:

to

And then i compiled and set, and voila, health is OK now. Thanks so much!

Hi ceph experts,
I just freshly deployed ceph 0.94.1 with one monitor and one storage
node containing 4 disks. But ceph health shows pgs stuck in degraded,
unclean, and undersized. Any idea how to resolve this issue to get
active+clean state?

only in RHEL7.1.
So you should consider to go to RHEL7.1 directly and upgrade to at least kernel

That is really great, thanks for your response, I completely understand what is

Can you check the capacitor reading on the S3700 with smartctl ? This drive has
non-volatile cache which *should* get flushed when power is lost, depending on
what hardware does on reboot it might get flushed even when rebooting.
I just got this drive for testing yesterday and it’s a beast, but
