I follow this guide https://developers.google.com/compute/docs/troubleshooting#ssherrors , namely the section on recovering your permanent drive using another vm.
I am trying to follow this part:
mount / dev / disk / by-id / scsi-0Google_PersistentDisk_myinstance-debugging / mnt / myinstance
This is the error I get:
root @ debugger : ~ # mount / dev / disk / by-id / scsi-0Google_PersistentDisk_marty-wll-debugging / mnt / marty-wll
mount: you must specify the filesystem type
I am not sure about the file system due to the use of computer computing you are using, and the system has already been removed and attached to another machine according to the Google Developer's Guide, which I referred to above.
parted scsi-0Google_PersistentDisk_marty-wll-debugging -l
root @ debugger : / dev / disk / by-id # parted scsi-0Google_PersistentDisk_marty-wll-debugging -l

gave me information that its "ext4".
although when I issue the following command, I still get the error message:
root @ debugger : ~ # mount -t ext4 / dev / disk / by-id / scsi-0Google_PersistentDisk_marty-wll-debugging / mnt / marty-wll
mount: wrong fs type, bad option, bad superblock on / dev / sdb,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
dmesg syslog :
