I was updating many millions rows in MySQL and there was a very big HDD load. I decided to decrease journaling by next options in fstab:
UUID / ext4 errors=remount-ro,commit=60 0 1
Bute after reboot I noticed than mount shows:
errors=remount-ro,commit=60,commit=0
So I need to remount manually by
mount -o remount /
Or I have changes in /usr/lib/pm-utils/power.d/journal-commit
JOURNAL_COMMIT_TIME_AC=${JOURNAL_COMMIT_TIME_AC:-120}
