How to disable auto fsck during boot for specific volumes

After 39 mounts of my 240 GB logical volume consisting of two 120GB SATA's, my initscripts decide that my SATA volume should get fsck'ed. Well this takes about an hour and I can't figure out where this '39' frequency is configured or how to disable it.

Very simply, I would like to know how to disable the forced fsck invocation, during boot, after 39 mounts of my ATA drives. This is an exceedingly long process that I would like to do on my own schedule. So far what I've done is to use noauto in my fstab in order to not accumulate so many mounts, since I only use this volume for multimedia storage. But how can I exclude my SATA's from this configuration so that fsck is not invoked automatically for them.

Thanks you for your kind assistance.

Ok, here's the short and skinny.

man fstab

No, seriously :-D

Now for the cheating way

/dev/md1 /var ext3 defaults 1 2
/dev/md2 swap swap defaults 0 0

See the 1 2 and the 0 0

It's the last number in your fstab that you want to set to 0, you won't get any more fscks on the volume. At least if I understand the man pages correctly.

For information purposes the number before the last one deals with dumps.

yeah i think if you change the last number to 0 it shouldn't check upon boot

Thanks guys. I actually did read the man pages first -- selectively that is. I thought those trailing numbers had to do with dismount orders or something so I selectively skipped over that part.

actually, i wasn't just aware of it until checked the manpage, this will come in useful with a laptop where i don't want to have it run fsck upon boot but for a server or workstation i would think it would be ok unless you're rebooting often, like a dual boot system.

I suspect this will prevent the volume being checked if it is not cleanly unmounted as well as stoping the
maximal mount count check. That seems like a bad idea to me.

You can change the number of mounts between check with tune2fs.
