Hi all,
We are working on jewel branch on a test cluster to validate some of the fixes.
But landed up in the following error when mapping an image using krbd on
Ubuntu 14.04.2 with 3.16.0-55 kernel version.
$ sudo rbd map -p pool1 rbd1
rbd: sysfs write failed
rbd: map failed: (5) Input/output

Hi James,
Are you mentioning SCSI OSD (http://www.t10.org/drafts.htm#OSD_Family) ? If
SCSI OSD is what you are mentioning, drive has to support all osd functionality
mentioned by T10.
If not, we have to implement the same functionality in kernel or have a wrapper
in user space to convert them

Something like erasure code plugins would suffice here? Each plugin has a

This is regarding generalizing the ceph-disk to work with different osd

Thanks. There are no changes from my end, just tried building the packages to
test internally with the latest code base.
0. 94-2.2 is intentional?

Hi Eric,
To add more context to the problem:
Min_size was set to 1 and replication size is 2.
There was a flaky power connection to one of the enclosures. With min_size 1,
we were able to continue the IO's, and recovery was active once the power comes
back. But
Sure. Will break them into multiple patches for easy review and merge.

Majority of the changes are segregating the files

We can extend this implementation to messenger and different backend of the

Hi,
We are trying to build CEPH on RHEL7.1. But facing some issues with the build
with Giant branch.
Enabled the redhat server rpms and redhat ceph storage rpm channels along with
optional, extras and supplementary. But we are not able to find gperftools,
leveldb and yasm rpms in the channels.
Thanks Sage and Loic. Will add the missing pieces and integrate the object
factory and plugin changes.

We have a test cluster with ~500 OSD's. This cluster has multiple rbd images

I am not sure, if Rocksdb/LevelDB can work on a raw device. When I looked at
