Missing raw - What happend?

[sunghost]

Hello,
i have a win2008 server with kvm and all was fine. i shut down the win machine and restart the host debian proxmox system 2.1. after reboot qm start tells me that the raw is missing:

volume 'local:100/vm-100-disk-1.raw' does not exist

I didnt delete anything, but what happend and where is my vm?

What kind of RAID controller do you use?

No raid, simply one sata hdd.

someone deleted the file or its the hardware defect. check syslog and dmesg and tests on your hardware/disk for defects. if everything is ok, restore your VM from backup.

running without raid is not recommended.

Hi,
what is the output of following commands?

mount | grep data 
df -k /var/lib/vz
find /var/lib/vz
cat /etc/pve/storage.cfg

hello,
none deleted it. its my system at home for testing and some machine like win2k.
mount | grep data
- no output

df -k /var/lib/vz
Dateisystem 1K‐Blöcke Benutzt Verfügbar Ben% Eingehängt auf
/dev/mapper/hamgujpc240034-root
300012112 55217120 229555212 20% /

find shows many lines because the other vm id is 101 and 102 the only info about missing raw from id100 is the empty dir

/var/lib/vz/images/100

cat /etc/pve/storage.cfg
[/quote]
dir: local

hope that helps

In this case, someone must delete the raw-file! Because the other images are present - this means, that the partition is successfully mounted.

The deletion of the disk can be happens long time ago. If you delete an opened file, linux use the file only for the file-locked proccess and mark the file as deleted. If you stop the proccess (like reboot) your file is gone...

Hello,
i checked the syslog and history for root and cant find any "rm" of the file. At least i resize the raw from 32gb to 42gb. before i make a snapshot of the not running win2k system. then restart win2k and grow the partition and as all seams to run fine, i delete the backup in the dump dir. is it possible, that the raw was not saved after shutting down the win2k at all and with the reboot of the hostsystem the raw was deleted anywhere? if i reboot or shutdown the hostsystem, i look with vzlist and qm list if a ll vms are down and then reboot the system.
