Hello,
We are running units in the field that are headless. Sometimes we get units returned that we when we boot them up have some type of filesystem inconsistency that the default preen doesn't fix but running fsck -y does.
I want to eliminate the -p (preen option) and always do the -y option anyone know where to make this change?
Thanks,

You can create a file called:
/etc/sysconfig/autofsck
inside there you need the following lines:
AUTOFSCK_DEF_CHECK=yes AUTOFSCK_OPT="-y"
That should take away all options except "-f" and use the ones you put in AUTOFSCK_OPT.

Thanks! Is that something we should have found in the documentation? I've always wondered why it wasn't the default. It is always painful when headless/remote machines fail to boot because of this, and the odds of anyone knowing more than fsck does about repairing a file system are essentially zero.

This is so true! I had this same argument back in the '90 with a NCR developer when their Towers did the same thing, and we using them as message switches in the public safety arena.

The reason it is not the default in CentOS is because it is not the default in RHEL.
As to why it is not the default in RHEL, I can't say for sure ... BUT ... -y (auto answer yes) is more dangerous that -p (preen). The definition of preen is "to automatically fix any filesystem problems that can be safely fixed without human intervention". When you do -y instead, it answers yes to everything ... including things that can't be fixed "without human intervention". That is not necessarily the safest thing to do. If you choose to do this, make sure you have good backups :D

I do sort-of understand the difference between the -p and -y - and the CentOS position on the subject. But seriously, how many people are going to be able to recover a filesystem better than fsck? And you need the backups anyway - the disk might really be dead.

Thanks much for the info.
