Re: [Xen-users] Xen with LVM
Ok, I guess it has not really something to do with LVM, cause I just
installed a (working!)
Centos5 guest into a (also working) Centos5 dom0 as imagefile. When I
try to mount the image
I get:
[root@serv106 ~]# mount -o loop /disk.img /mnt/loop/
mount: you must specify the filesystem type
So, very similar to the error before (actually the same). What is wrong
with my guest installation
that those are booting fine, but are not mountable?
Thanks for any help here,
Robin

Hello everybody, new in the Country (coming

I tried to install the first CentOS 5.0 - XEN -LVM machine but struggle
somehow. I followed
the explanations of
Paul, but CentOS 5 seems to have a problem with mounting the LVM after
installation:
http://lists.xensource.com/archives/html/xen-users/2007-07/msg00777.html
When I create a new lv named centos5 and do a mke2fs
/dev/vm-data/centos5
I can easily mount the "drive" with mount /dev/vm-data/centos5
/mnt/centos5. I unmounted centos5 then
and started the virt-install. Said for path /dev/vm-data/centos5 and no
graphics. Pretty soon the installer
comes up with "/dev/xvda currently has a loop partition layout. To use
this disk for the installation of CentOS, it must be re-initialized.."
I allow this but create my own partitioning (one Ext3 partition mounted
as / with full lv size).
Right after this step, the lv is no longer mountable and when checking
the "drive" says wrong superblock.
Is there an issue with LVM on Centos5, or did I do something wrong?
....tried everythign for several hours now :/
[root@serv106 ~]# rpm -qa |grep lvm
lvm2-2.02.16-3.el5
system-config-lvm-1.0.22-1.0.el5
I was also considering using file based domU's but still not sure if
they would give enough performance for a webhosting (LAMP) server.
Any help, hint or even URL that leads to an actual working howto is
greatly appreciated!
Thank you so much and have a great day now!
Robin
