vxfs error

[Deepak Seth_1]

host a - hpux 11.0 - pa-risc
host b - hpux 11.23 - itanium

importing VG from host a using map file (-s flag) . no problem importing to host b . however when mount the file system , it gives me this error

UX:vxfs mount: ERROR: V-3-21270: /dev/vgora-bvdb1/lvol1 disk image is incompatible with this system

already did fsck on the above raw device .

((herhxp03 root):/users/dseth> fsck -y -o full /dev/vgora-bvdb1/rlvol1
fsck: /etc/default/fs is used for determining the file system type

OK to clear log? (ynq)y

)

Is it a issue with different version of h/w server or something else like vxfs version . Earlier threads were not very useful in resolving the issue.

Any help appreciated.

Do you have different versions of vxfs installed. Try

fstyp -v /dev/vgora-bvdb1/rlvol1 | grep version

Hi:

Your VxFS filesystem layout version on 11.0 isn't support on the VxFS software you run on 11.23.

Run:

# mkfs -m /dev/vgNN/lvolx

...to see the layout version number

See:

http://docs.hp.com/en/B3921-60631/vxfsconvert.1M.html

vxfs version is same on both the server .
host a - pa-risc
(herhxp03 root):/users/dseth> remsh bvdb1 /usr/sbin/fstyp -v /dev/vgora/rlvol1 | grep version
version: 3
host b - itanium
(herhxp03 root):/users/dseth> fstyp -v /dev/vgora-bvdb1/rlvol1 | grep version
version: 3
==============
host b - itanium
mkfs -m /dev/vgora-bvdb1/rlvol1
mkfs: /etc/default/fs is used for determining the file system type
mkfs -F vxfs -o ninode=unlimited,bsize=1024,version=3,inosize=256,logsize=1024,largefiles /dev/vgora-bvdb1/rlvol1 512000

vxfsconvert gives a core dump

Hi (again):

Oops, 'vxfsconvert' only supports conversion of an HFS to a VxFS filesystem. I should have pointed you to 'vxfsupgrade':

http://docs.hp.com/en/B3921-60631/vxupgrade.1M.html

Put your volume group back on your 11.0 system and update your disk layout version there using 'vxupgrade'.

*READ* the manpages for 'vxupgrade' before you run it and make sure that your 11.0 system has JFS 3.3 as the manpages note.

After the filesystem has been upgraded to layout version-4, you should be able to export the volume group and mount the filesytsem on 11.23.

Regards!

Hi james,
that means i need to run the vxfsupgrade on the 11.0 system (host a) , which actually is a production system and i need to go through tons of approvals. I have many others houx 11.00 system . I looks like it make sense to use a PA-RISC system as a host a for this kind of work. What do u suggest .

[James R. Ferguson]

Hi (again) Deepak:

Well, any 11.0 system running JFS 3.3 (where version-4 layouts are supported) will do.

The idea is to be able to mount the version-3 layout and convert it to version-4 so that it can then be used on 11.23 with the uplevel JFS software.

I would urge you to backup the filesystem before conversion (safe is always good). Again, read the manpages I cited. You need some free space in the filesystem to perform the conversion.

Regards!

thanks for your help and advice . i tested upgrading the file systems version and they worked just fine . However i have lots of system with no JFS 3.3 , which is min requirement to convert to 4 . So let me think what is best approach to deal with this situation.
