Description Diego Ercolani 2011-03-31 15:14:46 UTC

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0.0) Gecko/20100101 Firefox/4.0

this is lvm2-2.02.67-4.1.1.x86_64 version.

I issued the lvresize command to add 5GB on a mounted ext4 filesystem. As you see from the log included, lvresize ask for confirmation telling that procedure WILL damage the filesystem. I answered "no" and the procedure have been done so.... fortunately no damage but why asking if you do the job?

The warning above is from e2fsck I think.
So nothing related to lvresize ;)

Would you confirm that?

Comment 3 Diego Ercolani 2011-05-13 08:02:45 UTC

Uhm... I don't know without reissuing the command but e2fsresize doesn't complain (as far I know) about resizeing a mounted extfs4.

The question is that I answered "no" and the utility ignored my answer... so why that utility is asking if it doesn't read my asnwer?

lvresize tries to call fsck before actually resizing.
I think it's e2fsck who WARN you at that time.

And your answer was taking care of, because the fsck step was skipped then.

lvresize continued without fsck.

Ok I understood, but from the user point of view, this is very confusing because it seem a warning by the lvresize utility that is asking confirmation to actually do the resize procedure.
