| 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 |
