217 pgs not deep-scrubbed in time

getting this error this morning, is there a way to lessen the interval on this?

 

1TB SSD journal for every 3 10TB 7200rpm SAS drives

after researching looks like its based on intervals and drive speed

http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-April/034097.html

 

do you recommend changing the interval or just letting it catch up?

i'd recommend to first increase the load threshold to allow scrub to run, from 0.3 to 0.6

ceph tell osd.* injectargs '--osd_scrub_load_threshold=0.6'

check value was set  ( X is osd numbet )

ceph daemon osd.X config show   | grep osd_scrub_load

to make this persistent, change the ceph.conf file

osd_scrub_load_threshold = 0.3 to 0.6

ive changed the conf file on all three nodes, I am guessing this requires a restart?

the conf file alone does require a restart ..but additionally the inject args will change it dynamically so it should not need restart

so far I've done

ceph tell osd.* injectargs '--osd_scrub_load_threshold=0.6'

 

and osd_scrub_load_threshold = 0.3 to 0.6

 

with a restart of all three nodes but it still shows 2 not scrubbed

Almost there, try

osd_scrub_sleep from 1 -> 0.5

as before, use inject + edit the config file..no need to restart

seems it has reverted again, not sure why these dates are showing, this is as of few minutes ago and time is accurate across all nodes

wait some more days with the new settings, if still the it persist, lower osd_scrub_sleep to 0.1
