File system

CLUTIER — Thu, 31 Jul 2003 06:25:26 GMT

Hi,
My server's name : louv-dev
I can't mount or unmount a file system : /dev/vgple_2/form
I don't have this in /etc/mnttab but i have an error msg in mnttab :
louv-dev:(pid669) /net ignore defaults 0 0 1059486902

In the /etc/fstab i have right entries :
/dev/vgple_2/form /pleiade/form vxfs delaylog,datainlog,largefiles,rw,suid 0 2

When i want to mount i have this msg :
louv-dev:/ #mount /pleiade/form
vxfs mount: mount option(s) incompatible with file system /dev/vgple_2/form

And when i want to unmount i have :
louv-dev:/ #mount /pleiade/form
vxfs mount: mount option(s) incompatible with file system /dev/vgple_2/form

Thx

Hi,

some notes:
/net ignore defaults 0 0 1059486902

this is not and error, it is an informative.
This is a default not being into account for automout. check /etc/auto.direct and /etc/auto.master.

/dev/vgple_2/form /pleiade/form vxfs delaylog,datainlog,largefiles,rw,suid 0 2

are you sure that delaylog and datainlog are compatible ? honestly i didn't remeber.
begin with tearing away the largefiles, maybe you didn't gave this property to the FS.

try with

mount /dev/vgple_2/form /pleiade/form

and see if it work. then add the options one by one.

i have others FS with these 2 options and it's worked.
i don't know how /etc/auto_master work :
/net -hosts -nosuid,soft

/pleiade/form isn't a new FS. I have lost it.
Yesterday i have mount a new FS in another VG.

-->>O.K., tear away the largefiles then :)

-->>... now i do not understand.
-->>in which vg did you created the fs ?

And i have lost /pleiade/form

Hi,
i was not clear.

/net is used in /etc/auto_master for auto_mounting remote FS when needed.

If you do not need this functionality, you can trim that line and, at next boot, it will be read.

We can also force automount to re-read it, but often this lead to some garbage.

This change do not prevent other nfs-mounts, only the automatic ones.

Regarding that FS....

how is the situation NOW ?

mount -p

CLUTIER — Thu, 31 Jul 2003 08:03:42 GMT

the situation is the same.
If i want to mount i have :
vxfs mount: mount option(s) incompatible with file system /dev/vgple_2/form

Run:

# fstyp -v /dev/vgple_2/rform

It will probably tell you that when the filesystem was set up. that it wasn't to include largefiles capability.

f_flag: 16 = largefiles
f_flag: 0 = no largefiles

# mkfs -F vxfs -m /dev/vgple_2/rform (will tell you how it was created)

If the filesystem has never been used re-run your newfs command. Hopefully this should work.

Hi,
what command do you use ?

did you try "mount /dev/vgple_2/form /pleiadi/form"

Can you post a "mount -p", please ? I want to check if it looks like already mounted.

Hi,
have you actually tried mounting it with
nolargefiles
instead of
largefiles?

regards,
John K.

Re: File system

CLUTIER — Mon, 04 Aug 2003 05:34:58 GMT

I have never tried to mount with nolargefile option. I have never modified this FS.
When I want to mount -a I have this msg :
vxfs mount: mount option(s) incompatible with file system /dev/vgple_2/form

Re: File system

HP-UX 11.11 eliminated the largefile/nolargefile option from /etc/fstab

If you are running 11.11(you don't say yes or no) and you have this entry in /etc/fstab it WONT mount.

Take out the largefile/nolargefile entry IF you are running HP-UX 11.11

uname -a

For your OS.

Is that directive in other filesystems? Probably not if they are mounted and this is an 11.11 box.

Hi

I think the others are trying to tell you to mount without largefiles enabled.

By default Filesystems are created without largefiles enabled, therefore trying to mount the filesystem will fail if it wasn't created with largefiles enabled.
As Michael said, check output of:
# mkfs -F -m /dev/vgple_2/form

Run this command:
# mount /dev/vgple_2/form /pleiade/form

If it succeeds then you can be sure your mount options in /etc/fstab are incompatible with the filesystem.

Cheers

Hi,
the reason for my former question was the following: the error message indicates that either the mount option in fstab is "largefiles" and the file system to mount has NOT allowed large files - or vice versa.

John K.

Follow on question for Stephen. Have a 11.11 system with a filesystem that wouldn't mount unless I removed the 'largefiles' arguement.
But, when I run 'mkfs' as suggested earlier, one of the arguments shown is 'nolargefiles'. I presume I have to rebuild the fs with the largefiles argument - correct?

thanks
