Mount 11.23 disk on 11.11

Michael Peddycord_1 — Fri, 26 Aug 2005 18:43:30 GMT

I have a disk created on HPUX11.23 and I want to move the disk to an 11.11 server. Anyone have a clue how to mount the disk on the 11.11 server. When I try to mount it I get
"vxfs mount: /dev/vg06/lvol1 disk image is incompatible with this system"

Thanks

The only known issue regarding this is if you were using an 8K sector size on your 11.23 disk, you need to apply PHKL_30927 to your 11.11 system to read it.

Hi Michael,

as Kent wrote it could be solved from patch PHKL_30927 or superseded PHKL_33285, here the text of the patch:

VxFS File Systems written on 8K sector sized devices cannot
be mounted.
#newfs -F vxfs /dev/rdsk/c5t9d0
#mount -F vxfs /dev/dsk/c5t9d0 /tmp_mnt
vxfs mount: disk image is incompatible with this system

Otherwise check the filesystem versions from HP-UX 11.23 system and 11.11 (are you using it by LVM or VxVM?

fstyp -v | grep version

You should have the same version.

HTH.

Best regards,
Fabio

I am using LVM. The version on 11.11 is 4 and the version on 11.23 is 5. I am using 16 K blocks, but I will try the patch to see if it makes a difference.
Thanks

The LVM version is the key. You can't mount a VxFS version 5 filesystem on a system that only uses version 4.

Hi,

Just upgrade to JFS 3.5!

Docs on how to do this can be found here (assuming you have 3.5 of course) :-)

Had the same problem on one of our backup servers mounting BCs off of an 11.23 production system.

Your vxfs (jfs) file system created on the 11.23 box ix not compatible with the 11.11 box.
You need to check what version it is, and probably upgrade your version on the 11.11 system by upgrading teh VxVM product.

Depends how it was created...

If you laid out the filesystem with

mkfs -F vxfs -o version=4

then yes you can....if you used newfs, then the default for 11.23 is version 5....
