Re: Ceph built from source gives Rados import error

Henry,
Because you compiled the sources, don't know where the librados is, but you cant find when is it called and go for there, maybe the error is not that is not properly imported, maybe is not where is suppose to be.

$ (strace ceph -s > myout) >& myerror

$ cat myerror | grep librados.so.2

The output in my case of the second command is the next, but I didn't build from source.

open("/usr/lib/x86_64-linux-gnu/librados.so.2", O_RDONLY|O_CLOEXEC) = 3


Did you try to find the library in your system? to see if is other location?, my system output:

$ locate librados.so.2

/usr/lib/x86_64-linux-gnu/librados.so.2

/usr/lib/x86_64-linux-gnu/librados.so.2.0.0


Best.

Hi all,

I built from source and proceeded to do a manual deployment starting on the Mon. I'm getting the error shown below and it appears that Rados has not been properly imported. How do I fix this?

Best,
