vxfs fsck: unrecognized vxfs version number

[EJ Stremler]

I have vgexported and vgimported a volume group that contains database file systems from one system running 11.23 to another system running 11.23.. I do an fsck -F vxfs -o full -y /dev/vg08/rlvol[123] before I mount the file systems up. I am receiving this error from the fsck.

system1:/root >fsck -F vxfs -o full -y /dev/vg08/rlvol1
vxfs fsck: unrecognized vxfs version number
invalid super-block
search for auxiliary super-block? (ynq)y

I then import the volume group to another 11.23 system and the fsck works fine. Wondering if there is a version mismatch of vxfs? How do I check? Any help would be great.. thanks, ed..

Hi Ed:

# fstyp -v /dev/vgNN/lvolXX

# mkfs -F vxfs -m /dev/vgNN/lvolXX

Hi Ed:

I should add, if you are running JFS 4.1 then you cannot mount disk layout versions prior to version 4. You can use the 'vxfsconvert' command to upgrade them, however, so that they can then be mounted.

hi ed ;
default filesystem versions are different between your platforms.
you need to check vxvm or vxfs fileset versions. system having lower vxfs version should be upgraded.

swlist -l | grep -i vx
