Help - Server wont boot after migration!

Posted on May 10, 2017

Hi - I’m getting an error on my ubuntu server after it was migrated during the digital ocean maintenance window. The console says

RAMDISK: gzip image found at block 0 RAMDISK: incomplete write (4871 != 24070) write error VFS: cannot open root device “LABEL=DOROOT” or unknown-block(0,0) Please append a correct “root=” boot option; here are the available partitions: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

and then the stack trace below that.

Any ideas? I"m desperate?

Fixed it myself - the kernel ramdisk had become corrupted in the transfer. Halted the machine, installed a new kernel via the control panel, and boot the machine. Console came up but no networking. Module deps weren’t available for the kernel I’d selected - powered off and switched to an older kernel that I knew I had modules for, reboot, and now the vm is fine and networking came up correctly.
