cannot use vgdisplay to check free space in a volume group

Hi, Experts:

I have an old linux with a mixmized out disk. I want to expand the disks but got the following error. Could someone help me resolve this error?


[jasony@lom-oraprd-02 jasony]$ su -
[root@lom-oraprd-02 root]# vgdisplay
vgdisplay -- ERROR: "/etc/lvmtab" doesn't exist or is unreadable; you may need to run vgscan

[root@lom-oraprd-02 root]# cat /etc/*-release
Red Hat Enterprise Linux ES release 3 (Taroon Update 6)
[root@lom-oraprd-02 root]# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume group

It may be a silly question, but does this old system actually use LVM? Please post the output of `df -k`

tfewster: right guess :)

you don't have LVM in place. Your disk is partitioned and on these partitions filesystems were created.
Check with
fdisk -l /dev/sda or
fdisk -l /dev/sdb

With some effort you can copy your data to a new LVM managed disk (aka Logical Volume).

How do you know that disks are full? The partitions that are shown are not full at all. Is there some application that gave an error and if so what is it?

I have received this email prompting me that the +DATA01 tablespace file is full. Is there a way I can expand this table space file.

it is oracle 10 g database.

Sure, you have plenty of free physical space, so either set Autoextend ON or increase the database size manually. I expect it's an Oracle FAQ, so a web search for oracle tips should turn up plenty of good material. Or delete this question and ask a new one with appropriate database-type keywords if you need a deeper analysis of your existing setup

Thank you, all these posts are helpful for me. I appreciate.

I will open another post in Oracle database field and learn the steps to change the "autoextend" parameter.
