RE: Lib snappy error

[Ramesh Chander]

Creating sym link at  /usr/lib/ceph/compressor/libceph_snappy.so from .libs/libceph_snappy.so.2.0.0 works for me

Not sure what is the right way though.

No I did't, is that mandatory even for dev environments?

Looks like path is hardcoded in any script.

'Make install' will put all the libraries in the path  (--prefix) you opted for during autogen (default /usr). You should do that in your dev env also just in case you have different version present.

I wouldn't recommand make install, actually.

This should work:

git clone git@github.com:ceph/ceph
cd ceph
./do_cmake.sh
cd build
make ceph_test_objectstore
ln -s . lib/compressor
cat  <<EOM > ceph.conf
[global]
plugin dir = lib
EOM
bin/ceph_test_objecstore ...

I'll fix up do_cmake.sh shortly so that it sets up the symlinks and 
ceph.conf the first time around.  Note that running ../src/vstart.sh will 
also create the symlinks and a ceph.conf that will make 
ceph_test_objectstore happy.

Re: Lib snappy error

[Igor Fedotov]

Shouldn't we remove compressor subfolder at all and store compressor 
libraries a level up?

>> Shouldn't we remove compressor subfolder at all and store compressor libraries a level up?
PluginRegistry class expects by default, that plugins of different
types are in separated directories. I added in one of PRs (not merged
yet) possibility to search libs in level-up directory too, if they are
not found in separated. May be it'll be a good variant, to have the
both possibilities.

Lib snappy error

[Ramesh Chander]

Hi All,

I am getting this error whatever I do:

[New Thread 0x7ffff1d70700 (LWP 14659)]
2016-06-28 08:00:02.395492 7ffff2d72700 -1 bdev(store_test_temp_dir/block) _aio_thread got (4) Interrupted system call
2016-06-28 08:00:02.395755 7ffff7fda6c0 -1 load failed dlopen(/usr/lib/ceph/compressor/libceph_snappy.so): /usr/lib/ceph/compressor/libceph_snappy.so: cannot open shared object file: No such file or directory
2016-06-28 08:00:02.395766 7ffff7fda6c0 -1 create cannot load compressor of type snappy
2016-06-28 08:00:02.395769 7ffff7fda6c0 -1 bluestore(store_test_temp_dir) _set_compression unable to initialize snappy compressor

I did full make. Did clean and make again but still it fails everytime.

I see in the path that it is looking for /usr/lib/ceph/compressor/libceph_snappy.so even though I am not installing ceph and using Vstart.

Any idea what is wrong here?
