[linux-lvm] lvcreate cores dump (NTCTA001 - MSV)

[norman at embratel.com.br]

Hi, I'm new to LVM but I'll try to provide
you with as much detail as possible...

I'm using LVM with a 30G disk. Initially this was a
partitioned disk (separated partitions for /usr, /tmp,
/var, /boot, / and /home). To use LVM without afecting my
performance I migrated the data from /usr, /home, /tmp and
/var, deleted them and now I have only the following mounted partitions:

Filesystem    1k-blocks Used    Available Use%  Mounted on
/dev/hdb5     822184    714968  65452     92%   /
/dev/hdb1     23302      1473   20626     7%    /boot

and i have a swap and a big partiton reserved for lvm as
follows:

Disco /dev/hdb: 255 cabeças, 63 setores, 3649 cilindros
Unidades = cilindros de 16065 * 512 bytes

Dispositivo Boot    Início      Fim    Blocos   Id  Sistema
/dev/hdb1   *         1         3     24066   83  Linux
/dev/hdb2          3546      3649    835380    5  Estendida
/dev/hdb3          3515      3545    249007+  82  Linux swap
/dev/hdb4             4      3514  28202107+  8e  Linux LVM
/dev/hdb5          3546      3649    835348+  83  Linux

Partições lógicas fora da ordem do disco

(sorry, the output of fdisk is in portuguese, but i think
you know the camps by heart :)
(I'll tranlate only the last sentence as I don't know if it
matters or not: logic partitions out of disk order.

That's ok. I then made:

vgscan
pvcreate /dev/hdb4
vgcreate vg01 /dev/hdb4

follows output from some commands and /proc entries:

well, when I try:

/sbin/lvcreate -L 2000 -n lv_usr vg01
or without spaces after -L and -n
or
/sbin/lvcreate -l 500 -n lv01 vg01
(changing spaces too)
or
/sbin/lvcreate -L2G -nlv_usr vg01
(changing spaces and changing lv name to lv01)

I get core dumped
I have a 2.4.10 kernel, with a 1.0.6 JFS patch and your latest 1.0.1-rc4 patches
applieds. (Note that no partition
was mounted using JFS (the partition I had I deleted to use
with LVM)). So both / and /boot are ext2.

I'll send you the core file, the /etc/lvmconf/vg01.conf and /etc/lvmtab.d/vg01
files (even not knowing if it'll help or not).
