Hello,
We are seeing slow requests while recovery process going on.
I am trying to slow down the recovery process. I set osd_recovery_max_active and osd_recovery_sleep as below :
----------
ceph tell osd.* injectargs '--osd_recovery_max_active 1'
ceph tell osd.* injectargs '--osd_recovery_sleep .1'
----------
But I am confused with the osd_recovery_max_chunk. Currently, it shows 8388608.
# ceph daemon osd.4 config get osd_recovery_max_chunk
{
"osd_recovery_max_chunk": "8388608"
In ceph documentation, it shows
-----------
osd recovery max chunk
-----------
osd recovery max chunk
Description: The maximum size of a recovered chunk of data to push.
Type: 64-bit Unsigned Integer
Default: 8 << 20
------------
I am confused. Can anyone let me know what is the value that I have to give to reduce this parameter ?
