Unable to mount a filesystem

Habib_4 — Wed, 12 Apr 2006 06:45:24 GMT

Hi guys,

When trying to mount a filesystem i get the following error:

vxfs mount: mount option(s) incompatible with file system /dev/vg01/lvol1

What is a solution to this?

Cheers

Ummmm . . . . . specify compatible options???

What have you got in your mount command? Post the output of "fstyp -v /dev/vg01/lvol1".

the mount options that you specified for this mount are not same what you have on lvol. Post mkfs -m /dev/vg01/rlvol1

What options you see?

mount with those options. Or do a plain mount without any options.
mount /dev/vg01/lvol1 /mount_point

Try this,

#mount /dev/vgXX/lvolX /
#mount /dev/vg01/lvol1 /abc

I usually got this message when the option for largefiles is not set correctly.

-check /etc/fstab and fsadm output on /dev/vg01/lvol1 to see their setting.

E.g
# more /etc/fstab
/dev/vg01/lvol1 /misc vxfs rw,suid,largefiles,delaylog,datainlog 0 2

# fsadm -F vxfs /dev/vg01/rlvol1
nolargefiles

-My example showing fstab for bootup setting has largefiles and fsadm showing no largefiles; this is causing the error. Or if the setting is the other way, you will get the same error too.
-For this case, i will use fsadm command to set the largefiles so that will be same with /etc/fstab setting.

# fsadm -o largefiles /dev/vg01/rlvol1

1.) Edit the fstab file in /etc.
vi /etc/fstab

2.) Check for an entry in the line for that file system that says:
largefiles

3.) Remove this entry from the line and that will fix the issue.

EXPLANATION: When the largefiles option is set in the fstab file the error message vxfs mount: mount option(s) incompatible with file system will appear. The reason is because the file system is not setup for largefiles. To setup the file system for largefiles run one of the following commands.

umount the file system umount /mountpoint and run the command:
#fsadm -F vxfs -o largefiles /dev/vgXX/rlvolX

or

With Online JFS or Advanced JFS just run the command:

#fsadm -F vxfs -o largefiles /mountpoint

Now the fstab entry for largefiles can be put back in, however the entry is not
needed for largefiles to be activated. Once the file system is setup for
largefiles, it will now be enabled for largefiles anytime it is mounted.

This same error could occur if nolargefiles is an option in /etc/fstab, and the
file system has large files enabled.

NOTE: To see if a file system is set to largefiles or nolargefiles do one of
the following:

1.) fsadm -F vxfs /mountpoint (vxfs only)
2.) mkfs -F vxfs -m /dev/vgXX/lvolX (vxfs only)
3.) fstyp -v /dev/vgXX/lvolX | grep f_flag
(f_flag: 0->nolargefiles, f_flag: 16->largefiles)
4.) fsadm -F hfs /dev/vgXX/rlvolX (hfs only)

It might very well be a largefiles issue but w/o posting the output of either...

# mkfs -F vxfs -m /dev/vgXX/lvolX
OR
# fstyp -v /dev/vgXX/lvolX

...it's hard to tell, so post the output of one of the above.

cheers!
