Hi, I'm seeing this error trying to map an rbd. root at 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 name=ff-ceph01-export,key=client.ff-ceph01-export hosting_linux_sharedweb linux_ded_backup_01", 147) = -1 ERANGE (Numerical result out of range) Many thanks.
