How to create a 100GB (/oracle) filesystem


newfs ??

[James R. Ferguson]

Hi:

Yes, 'newfs' is what one uses to create a filesystem. See the manpages (your friend! for more information, in particular 'newfs_vxfs(1M)'.

Hi JRF..

Thank you..

I actually have VG01...

how do I go from there

[Patrick Wallek · Accepted solution]

You need to first create a logical volume.

# man lvcreate

for details on how to do that.

You can then use newfs on that LV.

# man newfs

for details.

Can you help me out with the steps plz

[Grayh]

Also for /oracle of 100 G which one is recommended ----hsf or vxfs

[James R. Ferguson]

Hi (again):

I suggest you read chapter-6 of this document:

http://docs.hp.com/en/B2355-90950/index.html

I would urge you *NOT* to add non-standard, non-operating system filesystems and logical volumes into vg00. Keep vg00 devoted to the standard HP-UX logical volumes. This makes upgrades, cloning and disaster recovery much cleaner and easier.

Regards!

I have created VG01 on the second disk... But they want me to create the filesystem on the first disk itself...

Can you give me a push/Starting from where I can carry on...

maybe shell i create a new VG or directly shell i start from lvcreate

[Grayh]

Shell I create a VG with fs of 100G

what is the command to make it 100 G

[James R. Ferguson]

Hi (again):

HFS filesystems are deprecated. Use VxFS ones.

> I have created VG01 on the second disk... But they want me to create the filesystem on the first disk itself...

What volume group? You only have vg01 in your 'lvmtab'. Basically:

# pvcreate /dev/rdsk/
# mkdir /dev/vg01
# mknod /dev/vg01/group c 64 0x010000
# vgcreate /dev/vg01
# lvcreate -L 100000 -n lvol1 /dev/vg01
# newfs -F vxfs -v -o largefiles /dev/vg01/rlvol1

# cat << !EOF >> /etc/fstab
/dev/vg01/lvol1 /oracle vxfs rw,suid,largefiles,delaylog,datainlog 0 2
!EOF

# mount -a

Regards!

Usage:
For creating version 1.0 volume group,
vgcreate
[-V 1.0]
[-f]
[-A Autobackup]
[-x Extensibility]
[-e MaxPhysicalExtents]
[-l MaxLogicalVolumes]
[-p MaxPhysicalVolumes]
[-s PhysicalExtentSize]
[-g PhysicalVolumeGroupName]
VolumeGroupName PhysicalVolumePath ...

For creating version 2.x volume group,
vgcreate -V Version -S VolumeGroupSize -s PhysicalExtentSize
[-A Autobackup]
[-x Extensibility]
[-g PhysicalVolumeGroupName]
VolumeGroupName PhysicalVolumePath ...

For volume group version 2.x,
vgcreate -V Version -E
{-S VolumeGroupSize |
-s PhysicalExtentSize}

Note: The "-f" option is not available for volume group version 2.0 or h
igher.
More arguments required.

# lvcreate -L 102400 -n oracle vg01
lvcreate: Volume group "/dev/vg01" does not exist in the "/etc/lvmtab" file.

[Patrick Wallek]

Well, according to the 'strings /etc/lvmtab' output you provided earlier you only have VG00.

So if you want VG01 to have the other disk, you must create.

With the vgcreate statement you ran earlier you did not supply a disk to create the VG on. Try the vgcreate again, but specify the disk to use as well and then try your lvcreate statement.

# man vgcreate
for more information
