Proxmox Storage Extend: VM Not Booting Up

rafathossain

I have install proxmox in my local machine. I tried to extend the VM Storage from 50GB to 200GB. After extending the VM it's not booting up. I tried with other local machine with same config. There the VM extend was working fine. But now in the current VM it's not booting.

I have booted a live CD and tried to mount the partition but it failed. Here is the output below:

[root@livecd ~]# fdisk -l

Here is the error while trying to mount

[root@livecd ~]# mount /dev/sda1 /mnt/recover
mount: you must specify the filesystem type

[root@livecd ~]# mount /dev/sda1 /mnt/recover -t ext4
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

[root@livecd ~]# mount /dev/sda1 /mnt/recover -t xfs
mount: unknown filesystem type 'xfs'

Here is the output for badblocks:

[root@livecd ~]# badblocks -v /dev/sda1

Checking for bad blocks (read-only test): done

Do you have any idea about this problem? Any solution?

mount: unknown filesystem type 'xfs'

What's the actual actual fs of the partition?

the first question here is HOW did you extend the disk.

most likely in your process of extending something went wrong. if you're lucky it's just the bootrecord and grub missing something. if not you potentially messed up/broke the filesystem itself.

while you can simply resize (grow) the image within proxmox control panel, that would not change the partition or filesystem size at all. yet, from your fdisk it can be seen, that this has been adjusted already, so you probably did some more steps in between - the question is, what exactly did you do? ;-)
