Hi,
Is it safe to run tune2fs -c -1 -i 0 /dev/sda2 on mounted file system
Basically, this is a command to disable fsck based on reboot count & last fsck time.

Yes.

The RHEL/CentOS installed does exactly this, -c 0 -i 0, so yes it's considered safe.

Hi,
It would be much better controlling this values from your /etc/fstab file, so in case of any future references to fsck on boot, you will know what's configured by file. man fstab , and read about the sixth field.

I would disagree with that as there's a difference in semantics. If you set the 6th fstab field to zero, checks are never performed at all; this is suitable for read-only mounts and other special cases. Going the tune2fs route, though, just turns off the flags that say, "this filesystem appears to be clean but it's been a while since we checked, so we're going to check anyway". If you set the tune2fs flags to zero but leave the fstab flag set, then as long as you've done a clean shutdown you will not get an fsck on boot. OTOH if you've had a crash, the filesystem will not be marked as clean and it will be checked at the next boot, which is a whole lot safer than just using it. With journaled filesystems, it's also relatively fast.
I can't think of a situation where I would have a "normal" local filesystem mounted read-write but for which I would disable fsck in fstab.
