Re: osd does not start when object store is set to "newstore"

[Krishna Mohan <mohankrimailing@xxxxxxxxx>]

re-init the osd with the following command

sudo ceph-osd --id 0 --mkkey —mkfs

and then restart the osd again.

I hope it works.

I tried with leveldb, osd does not start either

osd objectstore = newstore

newstore backend = leveldb

enable experimental unrecoverable data corrupting features = newstore leveldb

I think you need to build code with rocksdb enabled if you are not already doing this.

 

Go to root folder and try this..

 

./do_autogen.sh –r

 

Thanks & Regards

I tried adding "enable experimental unrecoverable data corrupting features = newstore rocksdb" but no luck.

 

Here is the config I am using.

 

[global]

.

.

.

osd objectstore = newstore

newstore backend = rocksdb

enable experimental unrecoverable data corrupting features = newstore rocksdb

Hi,

 

I built and installed ceph source from (wip-newstore) branch and could not start osd with "newstore" as osd objectstore. 

 

$ sudo /usr/bin/ceph-osd -i 0 --pid-file /var/run/ceph/osd.0.pid -c /etc/ceph/ceph.conf --cluster ceph -f 

2015-05-08 05:49:16.130073 7f286be01880 -1 unable to create object store

$

 

#### ceph.config ( I have the following settings in ceph.conf)

 

[global]

osd objectstore = newstore

newstore backend = rocksdb

 

enable experimental unrecoverable data corrupting features = newstore

 

The logs does not show much details.

 

$ tail -f /var/log/ceph/ceph-osd.0.log 

2015-05-08 00:01:54.331136 7fb00e07c880  0 ceph version  (), process ceph-osd, pid 23514

2015-05-08 00:01:54.331202 7fb00e07c880 -1 unable to create object store

 

Am I missing something?

 

Regards

Srikanth
