vxfs version 5 compatibility

[Michael Tully]

Hi,

I've been attempting to mount a set of BCV LUN's/VG/LV/FS to a 11.11 system, that the original LUN's were created on a 11:23 itanium system.

During the import I get this message:

HPUX 11:11 system
# fsck /dev/ora3/ora13
fsck: /etc/default/fs is used for determining the file system type
vxfs fsck: unrecognized vxfs version number
invalid super-block
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

# fstyp -v /dev/ora3/rora13
unknown_fstyp (no matches)

From the 11:23 system
# fstyp -v /dev/ora3/rora13
vxfs
version: 5
f_bsize: 8192
f_frsize: 1024
f_blocks: 211943424

f_files: 51944776
f_ffree: 51944744
f_favail: 51944744

f_magic: a501fcf5
f_featurebits: 0
f_flag: 16
f_fsindex: 9
f_size: 211943424

So hear is my question, will or is vxfs version 5 supported on HPUX 11:11 ?

I've looked hear, but I don't know how old this document is.

Any help would be appreciated.

Hi Michael:

I don't believe that a version-5 layout is supported for 11.11. With 11.23 and JFS version 3.5 it is, of course. This version of the document you cited is newer:

p.s. Nice to see you here again :-)

Hi Jim,
Good to be back even if briefly. I have another question related to this.

Is it possible to change the vxfs version 5 on my itanium box (11:23) back to vxfs version 4? Or do I have to bite the bullet and flatten it?

Cheers
Michael

Hi (again) Michael:

According to the 'vxupgrade(1M)' manpages, you can't downgrade disk layout versions.

Warmest regards!

It's good to see you here again, even if only briefly. Keep well down-under :-))

Thanks Jim,

A flattening it will have to be.

Just for clarity sake, and to let other people know when you wish create a filesystem and you wish to make it an older vxfs type, here's the example I will be using.

# mksf -F vxfs -o largefiles,version=4 /dev/ora3/ora13

Cheers
Michael
