device file problem

[aamir4u]

Hi, 

After reboot my filesystem(c03) not there

Wheni try mount

#mount -F vxfs /dev/ORAVG02/c03 /c03

mount: /dev/ORAVG02/c03: No such file or directory

When i go to under/dev/ORAVG02 dir

there is no device file ?

ll /dev/ORAVG02

total 0 crw-rw-rw-   1 root       sys         64 0x080000 May 26  2011 group

How can recover it?

in c03 has very important data

How can again mount it  and recover my c03 filesystem?

>How can recover it?

Do you know how it was lost?

Do you have an ignite backup of your system?  If so, it would be easy to restore.

Could you please paste this again in a better format?

Please show

# ls -l /dev/ORAVG02

[aamir4u]

there is output

ls -l /dev/ORAVG02

total 0 crw-rw-rw-   1 root       sys         64 0x080000 May 26  2011 group

and also sent you my server lvmtab file attached mail

Please see it

This is strange. lvmtab is showing 3 disks, vgdisplay only 2.

There is no special file for any LVOL.

Please post

# vgdisplay -v /dev/ORAVG02
