Change hfs vxfs

[castro_2]

In 10.20 there is some way to change the hfs to vfs.?
Thanks

[A. Clay Stephenson · Accepted solution]

Yes.

1) Backup.

2) umount

3) newfs -F vxfs

4) mount

5) restore

You can do this on any filesystem except /stand which MUST be hfs.

There is no "magic" way to convert a filesystem.

You cannot do this direclty. As mentioned, you need to take full system backup and recreate each file systems. There are tools available to upgrade JFS from one version to other, not for hfs.

[castro_2]

and with online JFS
Thanks

[A. Clay Stephenson]

Sorry, even with OnlineJFS there is no way to do this "on the fly".

[Helen French]

No. Even with online JFS, you cannot convert an hfs file system to vxfs.

Or if you have additional disk space, you can create a new vxfs FS and cpio the data over. For example .. existing HFS mounted filesystem(/prodata say 1.2GB)on /dev/vg01/lvol1. You can create (either on the same VG or different VG - if space permit). Lets assume on the same VG.
# lvcreate -L 1200 -n lvol3 /dev/vg01
==> lvol3 is new to vg01
# newfs -F vxfs /dev/vg01/rlvol3
# mkdir /dest ; mkdir /source
# umount /prodata
==> Can only be umounted if users are not accessing.
# mount /dev/vg01/lvol1 /source
# mount /dev/vg01/lvol3 /dest
# cd /source
# find . -xdev -depth -print | cpio -pudlmv /dest
# umount /source ; umount /dest
# vi /etc/fstab
==> Change the mount entries accordingly. It can look like this ..
/dev/vg01/lvol3 /prodata vxfs rw,suid,nolargefiles,delaylog,datainlog 0 2
# mount -a

Once confirmed ok .. clean up ..
# rmdir /source /dest
# lvremove /dev/vg01/lvol1

Hi Castro:

Here's another good reason to move from ancient 10.20 to 11i operating system. In 11i you have the ability you desire with the 'vxfsconvert(1M)' utility. See here for more information:

Don't do this to the /stand filesystem. Kernel sits there. MUST be HFS.

Not unless you don't like your system to boot.

There may be other filesystems in 10.20 that can not be converted as well.
