Hi Greg,

thank you for your time!

#ceph-s

   cluster <id>
     health HEALTH_WARN
            62 requests are blocked > 32 sec
            noscrub,nodeep-scrub flag(s) set

  client io 56771 kB/s rd, 18844 kB/s wr, 2037 op/s


The warn comes from the noscrub flags ( neccessary currently because the
iscsi rbd reacts >very< bad on it )

[root@cn201 ~]# cat /etc/ceph/ceph.client.admin.keyring
[client.admin]
        key = mysuperkey123

The cluster is very active and working perfectly.

But the other access goes over the rbd kernel module and is working fine.

Just the access via ceph-fuse is causing trouble.

Is it possible, that its a problem with flushing pages, just concerning
ceph-fuse and not the rest ?

How can i check that at best ?

Thank you !
