Hi all,
I have a question about the I/O of cephfs.
I configure cephfs with 2 OSDs, and 300PGs in two HDDs. Then I use the iostat
(iostat -kx 1 /dev/sdd1) to monitor the I/Os of the HDDs (/dev/sdd1).
The result is as follows:
The iostat shows that there are write requests every second. However I do not
execute any applications.
What the source of the write I/O?
Thanks.
Best regards,
Fei Xia
