Hi,
Could you please advise me, whether it is possible to change the blocksize of vxfs filesystem on HP-UX 11.31 without destroying data there?
Thanks in advance for help

Hi:
As far as I know, no, the blocksize of a VxFS filesystem is set during creation ('mkfs_vxfs') using '-o bsize=n' where 'n' is a power-of-two between 1024 and 8192 inclusive. In order to change its value, I believe that you will have to backup the filesystem, recreate it and reload your data.
See the 11iv2 manpages (since the online 11iv3 ones are absent):
http://docs.hp.com/en/B3921-60631/mkfs_vxfs.1M.html
See especially the section on VxFS Version 5 Disk Layout File System Sizes therein.
Regards!

Re: Filesystem block size
"... since the online 11iv3 ones are absent ..."
I noticed this too, there is no page for newfs_vxfs, fsadm_vxfs ... ???
http://docs.hp.com/en/B2355-60130/fsadm.1M.html
Unfortunately, even the existing man pages on docs.hp.com are based on the initial version (Feb. 2007) only; but even the release notes for newer releases (seen in What's new in March 2009 - ioscan - new options) points to these old online man pages (of course without the new options...).
A bit OT, I know.
I don't think it is possible to change that without new creation.
Hope this helps!
Regards
Torsten.
