Hi everyone,
I have a problem with my ceph storage, it is showing pgs stuck unclean warning, I tried to repair pages, and to restart monitors and OSDs but nothing worked. All the problems occurred after an OSD became 95% full, and everything in my cluster stuck!, then I used the command (ceph pg set_full_ratio 0.98), deleted unused machines, and everything worked again, but still have these warnings.

more details about my case are shown as follow:

How can I fix this warning??

thanks in advance for your replies
 
I red this tutorial before, I tried to repair and force recreate pgs, but nothing changed. the query command shows the following:

Thank you jeffwadsworth for your replies,
But actually I couldn't use the answer in the referenced URL, the OSDs in my case are working fine:
#ceph osd stat
osdmap e304: 3 osds: 3 up, 3 in; 77 remapped pgs

There is no network issues, each OSD contacts the others, ping commands and telnet to Monitors IPs/ports working very well!
 
Thank you all ,
the problem occurred after using reweight by utilization, the weight of osd.2 changed to 0.55003
2 1.79999 osd.2 up 0.55003 1.00000

when I changed the weight to 1, everything went good
ceph osd reweight 2 1


Thanks
