LINUX: ext4 fs

LINUX: ext4 fs

posted Apr 4, 2012, 4:18 AM by Mila Rahalevich

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}
