Thanks for the reply.

Ceph is version 0.73-1precise, and the kernel release is 3.11.9-031109-generic.

also rbd showmapped shows 16 lines of output.

Thanks again.  Tom.

Hi,

I'm seeing this error trying to map an rbd.

root@fh-ceph01-export01:~# rbd map
hosting_linux_sharedweb/linux_ded_backup_01 --id=ff-ceph01-export
rbd: add failed: (34) Numerical result out of range

Is perhaps the string I'm writing too large for /sys/bus/rbd/add? Output
from strace:

open("/sys/bus/rbd/add", O_WRONLY)      = 3
write(3, "10.66.104.64:6789,10.66.104.65:6789,10.66.104.66:6789

linux_ded_backup_01", 147) = -1 ERANGE (Numerical result out of range)
Hi Tom,

Can you give us your kernel version and ceph version?  Also, what's the
output of rbd showmapped | wc -l ?

Thanks,

                 Ilya
