... Is this the end of the road?
Of course not
If you can read your data, then you can save it somewhere else (perhaps to a better supported filesystem). I suggest that you do this now, if you can.
If you really, really
, want to write to this filesystem (and I admit I know nothing about ufs
), then the hint is there:
[ 6330.867118] ufs was compiled with read-only support, can't be mounted as read-write
So there is probably an option to compile your kernel ufs
module with write-support for ufs
It's not offered, so perhaps support is unreliable. You can probably still compile your kernel to provide support for this, but it may not work, and may break the current partition you have.
So before you try this, or anything else, please make a copy of the existing partition with dd if=/dev/sdwhatever of=image_of_ufs_filesystem.partition
This way, you have a backup file of the original filesystem partition that you can later go back to if you need to.
I am a bit out of my depth here: I have no idea what a "tru64" filesystem is, so I am simply offering you "generic" advice.
At least you have (possibly) managed to get it mounted. Can you read the files there?
Why do you need write access to this partition, and why are you using such an outdated filesystem?
With a lot more information from you, there may be a simpler answer.
Hope this helps, but you need to supply more information, or I am wasting my time.
