mount ext4 partition - Operation not permitted

root user

mount /dev/ada2s3 /mnt/

Operation not permitted

 

[covacat]

try -o ro

 

[cracauer@]

dmesg

Does /dev/ada2s3 even exist? Shouldn't that be ada2p'x's3?

 

[covacat]

ada2s3 is legit for a MBR setup

 

[ShelLuser]

Thanks covacat!

That leads us to my next question OP: what does # file -s /dev/ada2s3 tell you? Are we sure this is actually EXT4?

 

[covacat]

operation not permitted is usually when you try to mount rw an unclean fs. im not sure ext4 rw is supported at all. but -o ro should work

 

[cracauer@]

dmesg

 

[bakul]

mount -t ext2fs [I]special[/I] [I]mountpoint[/I]?

you’ll also need to kldload ext2fs

 

[deepforest]

dmesg

[cracauer@]

Is that a dmesg from after you try to mount? Or just boot?

Please provide the output of running the following commands under script(1):
ls -l /dev/ada2*
gpart list ada2
