Strange default mount options

Vesa P. · 2015-02-21 13:49:10

As I installed the basic bootstrap system, the mount options set into /etc/fstab by the pac-bootstrapper were "rw,relatime,data=ordered". Booting with those caused falling back to some emergency shell with nothing mounted. Replacing those mount options by "defaults" got things working better.

Maybe the default set "rw,relatime,data=ordered" should be checked by someone "in the know" ?

(Thanks if you bothered.)

What filesystem are we talking about?

And what is the "pac-bootstrapper"?

rw,relatime,data=ordered

has always worked for me, ext4.

What does the rest of fstab look like?

Which is probably why 'defaults' resolves to exactly that....

Hi,

Thanks for your replies and info requests.

- "pac-bootstrapper" meant basically "the bootstrap program whose name begins with pac-something"... The exact name is "pacstrap". Sorry, I was a little careless there

- The file system is ext4. fstab contains two entries:

/dev/sda1 / ext4 defaults 0 1
/dev/sdb1 none swap defaults 0 1

At boot time, the system complains that the root filesystem was not configured to be mounted read-write... or approximately so, as the boot text goes by quickly. It also complained that the swap thing could not be configured.
A complaint about not being for read-write also appeared when "rw,relatime,data=ordered" was there instead of "defaults" for /dev/sda1. Not sure about the swap thing then.

I think I created the files system on /dev/sda1 using command "mkfs.ext4 -m 0 /dev/sda1".

Regards,
Vesa

Not a Sysadmin issue, moving to NC...

I guess you actually meant genfstab, since that generated your fstab..? Looking at genfstab, I'm pretty sure it would have put 'defaults' in there, so I'm not sure what you edited? Was the 'defaults' in there or did you replace that? I'm also pretty sure genfstab would never mark your swap partition as fs-checkable...

Also, if you'd post the actual error-message maybe we could actually help you..

This is not correct. genfstab will never use "defaults", as /proc/self/mountinfo (and therefore findmnt) will never show "defaults".

This is correct.

This was not an fstab created by genfstab.
