Weird thing about fstab

i!
I've just bought a new harddrive, Western Digital 160GByte ATA100. I've made a single 160GByte partition on it; primary with ext3 filesystem; I've booted with gentoo LiveCD, ran fdisk /dev/hdc and made the partition. That I wrote mke2fs -j /dev/hdc1

That worked as usually. Then I modified the fstab by adding the following line:

/dev/hdc1 /mnt/hdc1 ext3 defaults,umask=000 0 0

Then I booted to gentoo and got an error at boot:

mount: wrong fs type, bad option, bad superblock on /dev/hdc1, or too many mounted filesystems.

The same error occurs if I write mount -a. However, If I write mount -t ext3 /dev/hdc1 /mnt/hdc1 it mounts without a problem. The partition is ext3, so it cannot be wrong fs type. Bad option - I don't see one. Bad superblock - I don't know what that is. And it can't be too many mounted filesystems, because I've tried removing other partitions, and I would still get the same error. So does anyone have an idea what is wrong?

EDIT: Yes:

Code: Select all

umask=000

This is not a valid mount option for Ext2/3 file systems.

does "mount /mnt/hdc1" work?

try messing with fstab options, go slim at first (ditch the umask for now) and see if it works...

It won't. This command uses the mount options in /etc/fstab. So it will try and use the umask option which IS NOT A VALID OPTION for Ext3 file systems.

alternatively just remove the incorrect option as I pointed out above.

That's not supposed to be a personal attack. BTW. Just clarifying my 1st post which obviously wasn't clear enough

I love you huw! You were right, it was the umask=000 parameter that was causing problems. I've noticed just one more thing. When I mounted ( with mount command ) annother partition, type reiserfs, it generated a couple of warnings. Now, one caught my attention:

warning: - it is in slow mode for debuging

Does reiserfs have some debuging mode that I am unaware of? ( is this causing my PC to run slower as it should? ).

Anyway, thanks for the help, as I was just about to give up ( spent the whole night trying to figure out what the matter was ).

that will be due to the missing notail option.

Apparantly adding this increases the performance of reiserfs. However there's no mention of this here: http://www.namesys.com/mount-options.html
