xen kernel ext3 beibringen.

Lord_Icon · Dec 28, 2012

Hi,

Open Suse bringt Xen in der aktuellen Version 3.4.11-2.16-xen mit.
Meine alten Images basieren auf ext3.
Startet ich nun die alten Images, erkennt Xen das ext3-Filesystem nicht.

Ein Blick in das Verzeichniss: /lib/modules/3.4.11-2.16-xen/kernel/fs/ zeigte schnell, das dieser Kernel ohne ext3 ausgestattet ist und somit mit diesem Format garnicht umgehen kann.

Code:

ls /lib/modules/3.4.11-2.16-xen/kernel/fs/

9p    affs  autofs4  bfs             btrfs       ceph  coda      cramfs  ecryptfs  exofs  freevxfs  fuse  hfs      hpfs   jfs    logfs  ncpfs  nfs_common  nilfs2  ocfs2  qnx4  quota     romfs     sysv   udf  xfs
adfs  afs   befs     binfmt_misc.ko  cachefiles  cifs  configfs  dlm     efs       fat    fscache   gfs2  hfsplus  jffs2  lockd  minix  nfs    nfsd        nls     omfs   qnx6  reiserfs  squashfs  ubifs  ufs

Weiß einer, wie ich ext3 in den Kernel bringen kann ?

VIELEN DANK für jedweden Hinweis !!!

Ich wette einen virtuellen Kasten Bier, dass die Ext-Familie statisch in den Kernel einkompiliert ist.

Sicher dass Deine alten Images kompatibel mit dem neuen XEN sind?

Lord_Icon · Dec 28, 2012

Die Wette gilt

Gibt es einen Befehl, wo mit Xen mitteilt, welche Filesysteme unterstützt werden ?

K.a. ob diese kompatibel sind. Der Gast selbst startet... in der Umgebung wird dann sda* erwartet... die ich per config reingegeben habe.

Deshalb gehe ich davon aus, das Xen mit ext3 nicht umgehen kann.
Mein anderer Gast hat xvda. das System selbst startet.

Das kannst Du mit cat /proc/filesystems überprüfen.

Edit: s vergessen

Lord_Icon · Dec 28, 2012

Code:

cat /proc/filesystems
nodev   sysfs
nodev   rootfs
nodev   bdev
nodev   proc
nodev   cgroup
nodev   cpuset
nodev   tmpfs
nodev   devtmpfs
nodev   debugfs
nodev   securityfs
nodev   sockfs
nodev   pipefs
nodev   anon_inodefs
nodev   devpts
        ext3
        ext2
        ext4
nodev   ramfs
        iso9660
nodev   pstore
nodev   mqueue
nodev   usbfs
nodev   autofs

Mist... der kernel scheint es zu können. Da bin ich dann das hier schuldig.

Doch n bissel vorschnell n rückschluss gezogen. Werd ich dann doch mal etwas tiefer in die Materie gehen müssen und mir die unterschiede von xen 2 auf xen 3 mal reinziehen.

Xen hat nichts mit Ext zu tun.
Auf dem Hostsystem läuft der Xen-Hypervisor welcher grösstenteils im Kernel läuft, dieser hat aber mehr oder weniger nichts mit dem Kernel der virtuellen Systeme zu tun; diese booten ihr vollkommen eigenes, paravirtualisiertes System.

Was genau gibt es als Fehlermeldungen im Bootprozess der Instanz?
Eventuell hat sich die Disk-Nummerierung geändert oder durch einen anderen Grund kann er seine Partition nicht mehr finden.

Loggen tut xen ja recht umfangreich. Leider nichts, was aus meiner Sicht hilfreich sein könnte.

Die DomU-Config sieht wie folgt aus. Mit Xen2 startet dieses System ohne Probleme. (Kernel + ramdisk einträge sind korrekt. sprich: Pfad + Datei sind vorhanden)

Code:

name="webmailer"
memory=512
localtime=0
kernel="/boot/vmlinuz-xen"
ramdisk="/boot/initrd-xen"
root="/dev/sda1"

disk = [ 'file:/raid10/webmailer/swap,sda2,w',
         'file:/raid10/webmailer/system,sda1,w' ]

extra="3 console=xvc0"
vif=['bridge=br0',
     'bridge=br1']

Der Bootprozess hängt an folgender Stelle. Ich habe jetzt aber nur die letzten paar in Frage kommenden Stellen kopiert.

In den letzten Log finde ich zwar eine Error-MEldung:

xc: error: panic: xc_dom_bzimageloader.c:607: xc_dom_probe_bzimage_kernel: kernel is not a bzImage: Invalid kernel

.. aber die ist wohl zu vernachlässig, da ich diesen Logeintrag auch bei einen funktionierenden System (auf xvda basis) habe.

Kein Plan, wo ich noch suchen könnte... die Logs sind nicht wirklich aussagekräftig.

Erbarmt sich einer zu Helfen... oder muß ich ab jetzt auf mein webmailer verzichten ?

Das sind die relevanten Logzeilen:

Code:

[    0.397782] register_blkdev: cannot get major 8 for sd
[    0.397792] vbd vbd-2050: 19 xlvbd_add at /local/domain/0/backend/vbd/4/2050
[    0.415041] register_blkdev: cannot get major 8 for sd
[    0.415048] vbd vbd-2049: 19 xlvbd_add at /local/domain/0/backend/vbd/4/2049
[    0.484101] XENBUS: Device not ready: device/vbd/2050
[    0.484109] XENBUS: Device not ready: device/vbd/2049

Den darauf folgenden Logzeilen nach, dürften das die (virtuellen) Festplatten sein, womit wir wieder bei meiner Frage nach der Kompatibilität sind.

Hi Joe,

im Web habe ich nach diesen Problem schon den halben Tag gesucht. Leider ohne großen Fortschritte.

Um weiter Daten zu liefern:

Das alte Xen-System: 2.6.27.7-9-xen
Das neue Xen-System: 3.4.11-2.16-xen

sda1 und sda2 vom Problem-DomU sind loop-Device.
Mittels mount -o loop system /mnt kann ich die Datei mounten.

Hast du eine Idee, was ich tun könnte um das Problem zu lösen.

xen kernel ext3 beibringen.
