Hello,
i see server %wa value get high and when doing "iotop -ao" i see top process is "[jbd2/dm-0-8]" its I/O percentage is higher than any other process: 30-55%
2.6.32-042stab093.5
CentOS release 6.6 (Final)
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg-root 904G 579G 280G 68% /
tmpfs 12G 0 12G 0% /dev/shm
/dev/sda1 243M 85M 145M 37% /boot
/dev/mapper/vg-tmp 1008M 34M 924M 4% /tmp
# tune2fs -l /dev/mapper/vg-root | grep has_journal
Filesystem features: has_journal ext_attr resize_inode dir_index filetype needs_recovery extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize
# mount -l
/dev/mapper/vg-root on / type ext4 (rw,noatime,discard)
Please any idea how to safely without reboot fix this?
