[linux-lvm] ERROR -6 activating volume group

[linux-lvm] ERROR -6 activating volume group

[Adrien Farkas]

Hi,

I'v got the following problem: I've created volume group, logical volume, everything ran okay. vgscan and vgschange both ran with no problems. Then I recompiled the kernel (2.2.10-ac) with LVM included and now the situation is:

vgscan runs okay, gives

vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found volume group "vg1"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created

but vgchange -a y gives

vgchange -- ERROR -6 activating volume group "vg1"

Anyone can guess what's wrong and how to avoid it?


Thanks in advance

here it is (it the attachments). just to note, vgchange -day gave

Trying to vfree() bad address (0804f030)
vgchange -- ERROR -6 activating volume group "vg1"

in addition to the attachment info.

yes, it's compiled as a module, that's right. one more (huh) thing to mention, usage count for LVM modules is _decreased_ after _each_ vgchange, so it's -6 right now.

I do, check ^^^

that's done, that's okay with me.

Hmmmm,
There's not too many paths in the code that return this error string.  This
looks like it's the value of errno, after a failed ioctl() call on
/dev/vg01/group.

It looks like it can open this file just fine, but fails sending the
ioctl() to it, with
#define ENXIO            6      /* No such device or address */

It looks like you may have compiled LVM as a module, but do not have it
loaded, or else, your group char device file /dev/vg00/group has
not been created correctly.

I'd strongly suspect that you do not have your module loaded, as this is
the most common problem.
If you want your lvm.o module loaded automatically by kerneld, add the
following lines to your /etc/conf.modules file
alias block-major-58 lvm
alias char-major-109 lvm

The other possibility is you do not have correct device files in /dev/vg01.
  Check their major/minor numbers.
