Hi,

Move the lvm tab and recreate it. Then give me the output

#mv /etc/lvmtab /etc/lvmtab.old
#vgscan

All the best

I hope you got this by executing,

# strings /etc/lvmtab

Some related symbols with /etc/lvmtab are extracted by strings.

hth.

hi zungwon.
/etc/lvmtab is not an textfile but a binairy (data) file.

#file /etc/lvmtab
/etc/lvmtab: data

therefor you can see strange caracters when using pg or more.

DO NOT edit the file!

hi,

u meant after doing "strings /etc/lvmtab"? if so, do not worry, those characters are a result of strings command looking for ascii chars in a binary file:

Hi,

It's fine, that's just a symbol. As long as your system is fine, this will not harm the system's processes.

You can re-create by using 'vgscan' command.

# mv /etc/lvmtab /tmp/lvmtab.ORI
# vgscan -v

Use 'strings' to see the contain of this file :

# strings /etc/lvmtab

Hope this information can help you.

Cheers,

u can view lvmtab only by strings, u can not edit it, if any thing wrong, recreate it.
mv /etc/lvmtab /etc/lvmtab.old
vgscan

Hi zungwon,

Don't worry it is affected from the strings command converting characters in ascii. I have the similar output even I have tried few time to recreate lvmtab with vgscan command.

# stings /etc/lvmtab should be helpful.
otherwise,
# mv /etc/lvmtab /etc/lvmtab.old
# vgscan -av

as your recommend, mv /etc/lvmtab /etc/lvmtab.old
and vgscan
but, It didn't changed.

As others have said, what you see IS NORMAL. The /etc/lvmtab is a BINARY file. If you attempt to do a 'cat /etc/lvmtab' you will see all kinds of garbage on your screen.

By doing a 'string /etc/lvmtab' you are picking out the ASCII bits of the file. This allows you to see the entries for your VG's and disks that are part of those VG's. You WILL also see other miscellaneous characters. That is entirely normal and is expected. NOTHING is wrong.
