Mount a file system permanently

Add your filesystem to the /etc/fstab.

And what are the oracle fs we normally have

No idea, this will depend on your setup of oarcle.

Hi,

if you mount file system from sam it adds the corresponding line to /etc/fstab. so it mounts automatically in start up.

Add mount point details in to /etc/fstab

A typical file system entry is as follows

/dev/vg00/lvol9 /sree vxfs delaylog 0 2

/dev/vg00/lvol9 --> Device name
/sree --> mount point
vxfs --> filesystem type

Actually I wanted to create two filesystems of 50 gig each..

say eg:
/dev/vgdatabase/lvolORA
/dev/vgsysystem/lvolOLA
/dev/vgsystem/lvolMLB

How can I do that...

show I do a vgcreate vgdb or will the above be a part of vg00 and a lvcreate lvolORA

Need more input..........
post the ioscan -fnC disk o/p
Which are the physical volumes u want to create the File system.
Create a separate VG for that ( recomended)
Then lvcreate, newfs, mount.....

Lets start over.

So you wish to create two 50GB filesystems in either one or more volume groups.

1) find 100GB of storage.
Your ioscan showed two devices on that looks like it is the OS drive of unknown size, the other that has no device files created ( or it was cut off ).
disk 3 0/2/1/0.0.0.0.0 sdisk CLAIMED DEVICE HP SG146BCBA

So lets find some free disk.
but first need to create the device files for 0.2.1.0.0.0.1 unless you simply cut them off in your previous post.

insf -eH 0.2.1.0

then repost:
ioscan -kfnC disk

While you are at it Post:
vgdisplay -v

OK.. Here is what you have.

Two 146GB drives.
One is in vg00 the other in vg01

Because you only have two disk and they are in separate vgs mirroring is out of the question unless we change the config.

So...
To create two 50GB filesystems in /dev/vg01
lvcreate -L 50000 -n lvol1 /dev/vg01
lvcreate -L 50000 -n lvol2 /dev/vg01
newfs -o largefiles /dev/vg01/rlvol1
newfs -o largefiles /dev/vg01/rlvol2
mkdir /myfs1
mkdir /myfs2
edit /etc/fstab and create entries so they are mounted at boot time.
e.g
/dev/vg01/lvol1 /myfs1 vxfs largefiles 0 2
/dev/vg01/lvol2 /myfs2 vxfs largefiles 0 2

mount /myfs1
mount /myfs2

If you want to mirror we need to talk about other config options, getting more disk, putting both disks in /dev/vg00(not recommended), having Mirror/UX software, etc...

Hi,

After creating vg lv and mountpoint directory you need to mount new lv's into them, open /etc/fstab go to end add this 2 lines modify vgname, lvname and mountpoint

/dev/vgname/lvname1 /mountpoint1 vxfs rw,nosuid,largefiles,datainlog,delaylog 0 2
/dev/vgname/lvname1 /mountpoint2 vxfs rw,nosuid,largefiles,datainlog,delaylog 0 2
