Apologies in advance for any incorrect/dumb phrasing; I’m extremely new to all this.
I lost the private key to an EC2 instance I was previously running and am trying to follow the instructions listed under “Connecting to Your Linux Instance if You Lose Your Private Key” in the below link. In short, it tells me to create a temporary instance using the same AMI as the original instance, and then “from the temporary instance, mount the volume that you attached to the instance so that you can access its file system”
I got up to 9c:
[email protected][ip]: ~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT xvda 202:0 0 8G 0 disk └─xvda1 202:1 0 8G 0 part / xvdf 202:80 0 8G 0 disk └─xvdf1 202:81 0 8G 0 part loop0 7:0 0 12.7M 1 loop /snap/amazon-ssm-agent/495 loop1 7:1 0 87.9M 1 loop /snap/core/5328 [email protected][ip]:~$ sudo mkdir /mnt/tempvol [email protected][ip]:~$ sudo mount -o nouuid /dev/xvdf1 /mnt/tempvol mount: wrong fs type, bad option, bad superblock on /dev/xvdf1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so.
Typing in “dmesg | tail” gives me:
[ 626.631886] EXT4-fs (xvdf1): Unrecognized mount option "nouuid" or missing value
I googled around but couldn’t find anything helpful. What am I doing wrong?
Thanks again for your help; happy to provide any more relevant information.
-o nouuid is only useful on XFS filesystems. It’s not clear why the option is not discussed in that document. Since the filesystem you’re trying to mount is ext4, you can omit the option.
