Hi,
After a reboot, all the partitions created on the SSD drive dissapeared
They were used by bluestore DB and WAL so the OSD are down
The following error message are in /var/log/messages
Jan 3 09:54:12 osd01 ceph-osd: 2018-01-03 09:54:12.992218 7f4b52b9ed00 -1 bluestore(/var/lib/ceph/osd/ceph-6) _open_db /var/lib/ceph/osd/ceph-6/block.db link target doesn't exist
Jan 3 09:54:12 osd01 ceph-osd: 2018-01-03 09:54:12.993231 7f7ad37b1d00 -1 bluestore(/var/lib/ceph/osd/ceph-5) _open_db /var/lib/ceph/osd/ceph-5/block.db link target doesn't exist
Then I decided to take this opportunity and "assume" a dead SSD thiuse recreate partitions
I zapped /dev/sda and then
I used this http://ceph.com/geen-categorie/ceph-recover-osds-after-ssd-journal-failure/ to recreate partition for ceph-3
Unfortunatelyy it is now "complaining' about permissions but they seem fine

Anyone had to deal with a similar issue ?
How d I fix the permission ?
What is the proper procedure for dealing with a "dead' SSD ?
