Hello All,
Unfortunately my virtual ceph cluster(virtual machines on VMware ESXI) felt
into strange state.
When i reboot one of ceph OSD machines (hostname=osd3), all of OSD daemons
that related to that host were down (it's normal).
But when that OSD host boots up, i couldn't make OSDs UP, Because when i
run this command to view my ceph daemons (*$ sudo systemctl -a | grep ceph*
), there was no
*ceph-osd@x.sevice* deamon to to got start by me.
*$ sudo systemctl -a | grep ceph *
*.*
*.*
*.*
* var-lib-ceph-osd-ceph\x2d2.mount loaded active
mounted /var/lib/ceph/osd/ceph-2 var-lib-ceph-osd-ceph\x2d5.mount
loaded active mounted
/var/lib/ceph/osd/ceph-5 var-lib-ceph-osd-ceph\x2d8.mount
loaded active mounted /var/lib/ceph/osd/ceph-8 session-1.scope
loaded active abandoned
Session 1 of user cephuser session-37.scope
loaded active running Session 37 of user
cephuser... *
so , when i run following command in that OSD host, my OSD daemon getting
UP.
*$ ceph-osd -i 2*
*$ ceph-osd -i 5*
*$ ceph-osd -i 8*
*....................................................*
*$ ceph osd tree*

0.09760 osd.8 up 1.00000 1.00000*
But, still there is no *ceph-osd@x.sevice *daemon to manage OSDs.
what is the problem ???

Albert
