VXFS 11.00 vs 11.23

Hello, I've created a test VXFS filesystem on HP-UX 11.00 and attempted to mount it on 11.23, and received an error. I also did the test the other direction, and received a different error. Regardless, both failed. So my questions are:

1.) Is there a way to make this work in either direction for VXFS filesystems?
2.) Are there any other filesystems that are cross compatible between 11.00 and 11.23 that are natively supported?

Thanks!

Hi:

Your VxFS layout version is probably too low for 11.23 and too high for 11.0.

Have a look at the 'vxupgrade manpages; in particular the "notes" section on layout version compatibility.

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

Regards!

Re: VXFS 11.00 vs 11.23

Thanks for the reply! I read through the link you provided, but it never mentions anything about 11.23, only 11.00 and 11.1x (and other lower revisions that aren't relevant). Also, it seems that the JFS version will be relevant to the discussion, since some VXFS/JFS combo's will apparently behave differently than others. Is there a matrix somewhere that helps explain this, or even another doc that includes 11.23?

Actually, nevermind...I think this does answer my question afterall, I misread a key part under the Notes section. What about alternative filesystems...any options there?

Shalom,

Alternative file systems?

NFS is still compatible between the two versions of the OS.

NFS shares on 11.00 can be mounted by 11.23 and vice versa. The speed of the transaction is going to be limited by network band width.

Hi (again):

> What about alternative filesystems...any options there?

You really don't have any alternatives. You certainly don't want the old HFS filesystem! If you must co-exist for some period with the unsupported 11.0 software, at least upgrade the filesystem's layout thereon to the minimum version supported on 11.23. Once your 11.0 system vanishes, upgrade your layout version again so that you can move onward.

Hello Marty
Not sure, but how about good old HFS.

do a man newfs.

Forgot to mention.
Take into account the drawbacks of using HFS.

check for advantages and disadvantages of using HFS over VXFS

Re: VXFS 11.00 vs 11.23

Thanks for the replies everyone! I find it amazing at the slight difference in releases of 11.xx use incompatible filesystems (both forward AND backward!?), but I guess that's the HP-UX world for ya.

My solution will be the old slow way of just creating new filesystems and using rsync to do the final cutover after an initial copy. Thanks again.
