[linux-lvm] Clarification

[Jason A. Lixfeld]

I'm just looking for clarification:

ext2resize will actually resize ext3 aswell?  With no extra flags?  It
will just know that the LVM is ext3 and not ext2?

I would say you better check it on ext2resize and ext3 man pages.  By
default I wouldn't expect ext2 tools to work with ext3 (anyway, you just
can test it on a non-production environment).

[linux-lvm] consistent lvcreate core dump (rc4 - 2.4.10)

[Tony Cox]

I'm new to LVM so apologies if this is a FAQ.

I just installed LVM-1.0.1-rc4 on a 486-based linux box running 2.4.10. It only
has SCSI disks running via a 53c710 chip on the motherboard. It also has an
adaptec 1540B scsi card installed but that only hosts a scsi CDROM.

The LVM kernel patch, module build and install went without a hitch. I have 5
2GB scsi disk each divided into 2 x 1GB partitions. I set the 8e partion flag
and created the PVs without and problem. I then created a VG with 4 of the
partitions (sda1/2 and sdb1/2). This went OK.

Finally when I came to create an LV I got a seg fault. Using the -v flag I found
that it got up to the part where it was: "creating logical volume VGDA in
kernel". Then it crashed.

The LV create command was:

lvcreate -V -L 1000M -n backup vg1

Could anybody tell me if I am doing something wrong? - or how to track down the
problem? 

The pvscan and vgscan utilties reported no problems and I tried
restarting LVM, inactivating, reactivating the GV and even deleting the whole
thing including the PVs and repeating the process - so it is completely
reproduceable in my situation.

thanks

Tony

I had that problem aswell.  I was using the stock compiler with RedHat
and switched to egcs 1.1.2 and it worked fine.

My guess is you're using redhat 7.1 with the dodgy release of gcc.
Try either building the tools without optimisation or upgrading your
compiler.

If it is unmounted, it will work fine.  There is no difference between
ext2 and ext3 for a (cleanly) unmounted filesystem (the journal is just
a regular file).  If you try to resize a filesystem that has a dirty
journal (e.g. after a crash) it will refuse to do so and you need to
run e2fsck.

Cheers, Andreas
