fsadm: /etc/default/fs is used for determining the file system type
If the conversion fails, due to I/O failure, for example, run fsck to return to the original file system.
fsck -F hfs /dev/vg01/rlvol5
To convert a file system on a volume manager (for example, LVM) volume, using only disk space at the end
of the file system (with the -s option), you may need to increase the volume size to provide the additional
space to do the conversion. If LVM is used, you can do the following:
vxfsconvert -e /dev/vg01/rlvol5
lvextend -L new_size /dev/vg01/rlvol5
vxfsconvert -s required_space /dev/vg01/rlvol5
After the conversion completes, the increased volume space becomes a part of the converted VxFS file sys-
tem.
Note: DO NOT reduce the volume after the conversion.
If the conversion fails, continue using the original file system. You do not need to run
fsck. Reclaim the
disk space by entering (on LVM):
lvreduce /dev/vg01/rlvol5 old_size
NOTES
To take full advantage of the VxFS file system, use
fsadm to reorganize the file system after the conver-
sion. The online reorganization feature of
fsadm is availablein only with the HP OnLineJFS product.
The converted VxFS file system uses the Version 4 disk layout, which is only recognized by JFS 3.3 and
later versions. Do not convert a file system which is shared by a system running HP-UX 10.x or HP-UX
11.00 without JFS 3.3.
You must call
vxfsconvert with its full pathname: /sbin/fs/vxfs/vxfsconvert
.
Quota conversion is not supported.
WARNINGS
Do not run
vxfsconvert on the /stand or whole-disk bootable file systems.
In the rare case of unsuccessful conversion, there is a risk of data loss or corruption. Always do a full sys-
tem backup before the conversion.
DIAGNOSTICS
All error messages, I/O failure, and exit messages display on standard output.
