[linux-lvm] lvcreate is segfaulting

[linux-lvm] lvcreate is segfaulting

[William Vadnais]

Hello--

I'm getting segfaults when attempting to build a
logical volume using lvcreate...

[root@mp3gimp /root]# lvcreate -v -n now -L 8G test
lvcreate -- checking volume group name "test"
lvcreate -- checking volume group existence
lvcreate -- checking volume group activity
lvcreate -- checking logical volume path
/dev/test/now" 
    [other verbosity ignored]
lvcreate -- setting up logical volume
lvcreate -- setting read ahead sectors
lvcreate -- creating logical volume VGDA in kernel
Segmentation fault (core dumped)

This is a Redhat 7.1 box with a custom kernel. I've
tried using both 2.4.9 and 2.4.10pre5 to no avail. LVM
module is compiled into the kernel directly and I've
applied the patches in the /PATCHES dir.  I've also
tried the latest tarball release of rc2 as well as a
CVS install as late as today (September 8th, 2001).

If anybody has any insight on this, i'd appreciate it.
Thanks.

-Willie

Hi

i was wondering
did you aplied the patches from PATCHES
or you did  run configure ; cd PATCHES ; make ;
and then aplied

it should be only one patch

Re: [linux-lvm] lvcreate is segfaulting

[William Vadnais]

Yes, i ran configure then make from within the PATCHES
dir then a cd /usr/src/linux and a patch < p1 using
the newly created lvm-CVS-2.4.9 patch file...

Sorry for the confusion in my original email, but I
only installed 1 patch.

Cheers,
-Willie

that's a typo i couldn't be misstaken ?

you could do

.... ; cd PATCHES ;make ; cat lvm-CVS-2.4.9.patch | patch -p1 -d 
/usr/src/linux

and what tells  " cat /proc/lvm/general " , could you attach it

Re: [linux-lvm] lvcreate is segfaulting

[William Vadnais]

it was a typo on my part. The patch is installed
correctly. I don't have a /proc/lvm/general, but here
is /proc/lvm/global:

[root@mp3gimp lvm]# ls /proc/lvm
global  VGs
[root@mp3gimp lvm]# cat /proc/lvm/global

LVM is compiled directly into kernel, not as a module.

I did remove completely the tools from the non CVS
version and then reinstalled LVM from the CVS source
(i did this previously, not just now ;)

[root@mp3gimp src]# strings /sbin/lvcreate | grep CVS
liblvm-10.so.CVS
Logical Volume Manager CVS
Heinz Mauelshagen, Sistina Software  CVS_DATE
[root@mp3gimp src]#

Thanks for the help, btw, it is much appreciated.

I had the same problem - it was fixed when I configured
with --enable-static_link.
