Hello,
im having Centos 6.6 and 2.6.32 kernel
2 HDDs in HW raid 1.
/dev/mapper/vg-root / ext4 discard,noatime 1 1
And there is an journaling process: [jbd2/dm-0-8] which has like 50% I/O usage for more than hour.
I have a few OpenVZ virtual servers. What are ideal settings for the filesystem? Can i tweak any related setting without rebooting server please?
Someone mentioned here that when "commit" is not set in fstab, then journal process is writting very frequently.
