Hi, wir hatten hier einen Stromausfall. Nun startet proxmox nur noch in emergency mode.

ich habe den verdacht das was mit der sda3 nicht stimmt. was kann ich machen? Ich will die Daten nicht verlieren / neu aufsetzen ... auf der sda sind die VM images drauf (weiss aber nicht auf 1,2 oder 3 - glaube aber auf sda3)

was braucht ihr von mir das ihr mir helfen könnt?
 
Schau dir mal /home/X-Backup an, das kann nicht gemountet werden. Im Rescue Mode die /etc/fstab editieren und den Eintrag auskommentieren. Dann sollte ein ordentlicher Boot möglich sein.
 
0.0 meinst das is alles :eek:

EDIT

leider auch nach dem auskommentieren nix anders

Steht im dmesg-output uU, welche disk, die Probleme hat - vl. hilft ein manueller fsck (je nach Zustand der disk)
 
bevor ichs vergess schon mal danke

kann ich im emergency mode SSH aktiveren? das ich die ausgabe hier posten kann?
er schreibt ca 20 seiten hin aber ich kann vll 1/2 hoch scrollen mehr geht nicht (warum auch immer)

EDIT:
so startet man den SSH Service:
Code:
sudo /etc/init.d/ssh start


das ist der output:

sieht auf den ersten blick nicht auffaellig aus (aber vielleicht kommt davor/dahinter noch was relevantes)

fsck bei den disks versuchen und haendisch mounten?
 
bei der die ich vermute kann ichs nicht testen da sie in use ist:

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem.  If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>
 or
    e2fsck -b 32768 <device>

kann es daran liegen das es im lvm2 format ist?

kann es was mit dem "invaid checksum" zu tun haben ? beim boot?

konnte nun booten, nachdem ich alle hdd' aus der etc/fstab raus hab.
 
welche "invalid checksum" meldung?

vom dmesg output sieht es so aus, als gaebe es ein mdraid, vom cfdisk output als gaebe es zumindest ein lvm - lsblk zeigt eine recht hilfreiche uebersicht ueber die blockdevices an.
fsck muesste in dem fall auf das lv mit dem filesystem gemacht werden.

je nach inhalt der fstab koennte es sein, dass eine disk getauscht wurde/entfernt wurde ohne dass /etc/fstab angepasst wurde. Das wuerde das lange wait und den rescue mode erklaeren
 
er bootet wieder, es hatte mir die ISO HDD (sdb) und die Backup HDD (sdd) zerschossen.
es war so wie du dachtest eine hdd die gemountet werden sollte hat den fehler verursacht.


DANKE dir soooooooo sehr!
