The funny thing is when I go into yast, those inactive volumes don't
show as being in any VG, it just has -- for the group name.

Ok, that looks fine.  The "inactive" just means that no Physical Extents
(PEs) have been allocated on the new volumes yet.  You've got 24MB left
on your dasdh1 PV, so if you create a 30MB logical volume and re-run the
pvscan, it should show one of the new volumes as being ACTIVE (most
likely dasdk1).

Can you show the actual output from that?  I can't say I've seen it
before.  And yes, the PVs are in the VG, even if they're marked
inactive.  Just try taking them offline and doing a vgscan.  Should be
ugly.

Richard, is the root FS really in the LVM you talk about? I.e you have the 
whole zLinux in LVM?

Assuming not, i.e. you have "/", "/boot", "/etc" in a non LVM FS, then you can 
forget the LVM disks, attach the disk with the root FS and mount the root FS on 
/mnt.

Then run command
chroot /mnt zipl

I'm doing this from my head, so can someone confirm :-)

Re: LVM Question

2005-03-17 Thread Post, Mark K
Once I found out about the e2fsadm command, I stopped using lvextend,
because e2fsadm does everything for you:
umount the file system
e2fsadm -L +1G /dev/vg01/lv0l1
mount the file system

It does the lvextend, then the fsck that resize2fs always requires, then the
resize2fs.  Lovely, and works just fine on ext3 file systems as well.

Re: LVM Question

2005-03-17 Thread Hugo Rivera
You don't have to.
First create new physical volumes:

pvcreate  /dev/dasdx1 /dev/dasdy1

Add new volumes to your volume group:

vgextend /dev/vgroup /dev/dasdx1 /dev/dasdy1

At this time you may see the new volumes added using "vgdisplay /dev/vgroup"

Unmount your file system:

umount /uxxx

Extend your logical volume:

 lvextend -L+1G /dev/vgroupx/volx (if you want to extend 1 giga).

Mount your file system:

mount  /dev/vgroup/volx  /uxx

I hope this can help you.

Compare the output of lsmod both before and after the reboot. Unless you ran
mk_initrd after the LVM modules were loaded it's very likely that they aren't
included in your initrd and, consequently, aren't being loaded at reboot.

Ok, this looks like a difference between LVM and the LVM2 that comes with
2.6.  I guess "vgdisplay" and "ls -l /dev/usrdata" might tell us something.

SLES9 for S/390 (31-bit) in an LPAR > (no VM) using a shared IFL

I must be missing something -- but things may be different under SLES9

Currently I have /srv filesytem under root.  I would like to "/srv" under
LVM.

I keep getting an error during the IPL stating "/sbin/fsck.reiserfs /srv
failed open the device /dev/usrdata/srv"?  What am I missing.  I have
successfully created the new volume group, added the physical dasd volume to
the group.  Created the logical volume group.  Ran fsck.reiserfs mounted the
device updated fstab and ran zipl.  There must be something else but I don't
see it.

Thanks

Re: LVM Question

2004-02-25 Thread Hall, Ken (IDS ECCS)
Yes, we confirmed this some time ago.  The number of stripes HAS to equal the number 
of physical volumes in the LV.

You can have a VG of, say, 10 PV's, with two striped LV's, 5 and 5 (both 5 stripes) or 
6 and 4 (6 and 4 stripes), but if you want all 10 PV's in one LV, it has to be 10 
stripes.

We have some very large LV's that are 29 stripes.  Seems to work fine.

What value(s) did you use for stripe?  I have seen someplace (and it makes
sense to me, and indeed has worked for me) that the number of stripes for
the logical volume should equal the number of physical volumes in the
volume group.  (It makes sense to me because this way you would be
spreading the data access evenly over all of the PVs in the VG.)

Did the volume group already have one or more logical volumes allocated?

Don't know what happened to my earlier reply, but I told him he needed to
create a logical volume as well as the volume group.

Thanks Josh!  That is what I needed to do.

Mark, I rebooted just because!  I wanted to see

It was pretty clear to me that I didn't need to

Re: LVM question

2002-07-24 Thread Marist EDU

After you create the volume group you need to hit F3 and add a Logical
Volume.

Then the name is:  /dev/NAMEOFVOLUMEGROUP/NAMEOFLOGICALVOLUME.

After that you mke2fs it.

Subject: LVM question


I've been trying to search through the archives, but it
never comes back to me so I'll ask here (sorry, I'm
sure this has been asked before).

I'm trying to use LVM for the first time.  I'm running
SuSE 2.4 kernel.   So I created my 2 minidisks,
dasdfmt 'd them, fdasd'd them, went into Yast and
chose the 2 disks and created a volume group called "prod".

I rebooted and see these messages so I'm pretty sure
it exists:

Scanning for LVM volume groups...
LVM version 0.9.1_beta7  by Heinz Mauelshagen  (10/04/2001)
lvm -- Module successfully initialized
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "prod"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group

Activating LVM volume groups...
vgchange -- volume group "prod" successfully activated

Now, I suspect I need to mke2fs it, right?  My question is
what is it called?   The s/390 distributions redbook seems to
indicate that it might be /dev/prod/lvol1, but this doens't
work or seem to exist.

Can someone buy me a clue?
