/var full, how to use lvextend ?

Hello,

We run Postfix and our /var is full :
/var Linux Native Filesystem (ext3) LVM VG sysvg, LV var 100%

We tried the lvextend command with something like :
lvextend -L+1G /var
but we get the error message :
"/var": Invalid path for Logical Volume
Any Idea ?

lvextend -L +1024 /dev/vg01/lvol10 /var

/dev/vg01/lvol10 is your physical volume

I got an error message :

Volume group "vg01" not found
Volume group vg01 doesn't exist

??

first identify your volume group

OK, I'll try, no danger to loose some datas ?

Michael Worsham

Nope. 'lvextend' only extends the logical volume limits.

However, 'lvreduce' can (and usually does) corrupt data as it is used to reduce the logical volume limits.
