Hi，all：
I test ceph-10.2.5.tar.gz (download on download.ceph.com/tarballs)
on AARCH64.
ceph cluster is OK：
cluster 7bb94b46-1111-42e9-aaca-6ed9832b73a5
health HEALTH_OK
monmap e1: 1 mons at {openSUSE=10.10.109.23:6789/0}
election epoch 4, quorum 0 openSUSE
osdmap e29: 4 osds: 4 up, 4 in
flags sortbitwise,require_jewel_osds
pgmap v135: 64 pgs, 1 pools, 14512 kB data, 11 objects
16609 MB used, 1845 GB / 1862 GB avail
64 active+clean
the rbd create hello --size 10240
I can put data into hello by rados， then
rbd map hello， but failed：
rbd: sysfs write failed
In some cases useful info is found in syslog - try "dmesg | tail" or so.
rbd: map failed: (110) Connection timed out
at that time，the ceph cluster also is OK.

I test v0.94 installed by ceph-deploy, then rbd map is OK! Why? How
can I solve it?
Thanks.
