Hi,
Today I installed the ceph deploy node on a common PC (AMD Athlon 64 X2
Dual Core Processor 5000+, 2G memory, one SATA Disk).
The OS: Ubuntu 12.04 with kernel 3.8.0-33-generic
I have followed this guide:

I double checked the apt-ke
Hi Greogory
Found the solution to my mounting problem today.
You where right the error message: libceph: mon0 10.100.214.11:6789 feature set
mismatch, my 4008a < server's 4004008a, missing 4000
Comes from wrong haspspool settings. The correct command to clear this flag is:
ceph osd pool set

No, you wouldn’t need to re-replicate the whole disk for a single bad sector.
The way to deal with that if the object is on the primary is to remove the file
manually from the OSD’s filesystem and perform a repair of the PG that holds
that object. This will copy the object back from one of th

Hi guys,
in the past we've used intel 520 ssds for ceph journal - this worked
great and our experience was good.
Now they started to replace the 520 series with their new 530.
When we did we were supriced by the ugly performance and i need some
days to reproduce.
While O_DIRECT works fine for b

OK, that's good (as far is it goes, being a manual process).
So then, back to what I think was Mihály's original issue:

I looked at the code. The automatic repair should handle getting an EIO during
read of the object replica. It does NOT require removing the object as I said
before, so it doesn’t matter which copy has bad sectors. It will copy from a
good replica to the primary, if necessary. By default a d
Thanks. I also found the version is incorrect, I changed it and
re-install, got successful.

Hi David,
Thanks for taking the time to look into this for us.
Isn't the checksum calculated over the data? If so, wouldn't it
then be easy for ceph to tell which copy is good (because the
checksum matches) and so an automatic repair should be possible?
Is the lack of this functionality once aga
All,
We've just discovered an issue that impacts some users running any of
the "ceph osd pool set" family of commands while some of their
monitors are running Dumpling and some are running Emperor. Doing so
can result in the commands being interpreted incorrectly and your

Hi,
Since the /dev/sdX device location could shuffle things up (and that would mess
things up) I'd like to use a more-persistent device path.
Since I'd like to be able to replace a disk without adjusting anything (e.g.
just formatting the disk) the /dev/disk/by-path seems the best fit.
However,
Hi,
When an osd node server restarted, I found the osd daemon doesn't get
started.
I must run these two commands from the deploy node to restart them:
ceph-deploy osd prepare ceph3.anycast.net:/tmp/osd2
ceph-deploy osd activate ceph3.anycast.net:/tmp/osd2
My questions are,

I deployed one monitor daemon in a separate server successfully.
But I can't deploy it together with the osd node.
I run the deployment command and got:
