Multi-MDS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
     I did the configuration to activate multimds in ceph. The parameters I entered looked like this:
3 assets
1 standby

     I also placed the distributed pinning configuration at the root of the mounted dir of the storage:
setfattr -n ceph.dir.pin.distributed -v 1 /

     This configuration is working well, but the balance between the MDS ranks is not ok. Look:
RANK  STATE               MDS                 ACTIVITY     DNS    INOS   DIRS   CAPS  
 0    active  lovelace.ceph05-ceph.bpqxla  Reqs:   91 /s  1396k  1078k   179k   176k  
 1    active  lovelace.ceph01-ceph.rncaqh  Reqs:   18 /s   862k   571k   110k   292k  
 2    active  lovelace.ceph02-ceph.yarywe  Reqs:  1155 /s  12804k  12830k   1251k  11672k  

     Is there any extra configuration to improve this balance that I haven't done?

Thanks
Rafael.
