thanks,
i do as you said, but after loading gjournal, dd says "operation not
permitted".
gjournal clear says "operation not permitted" too and therefore "gjournal
label" is not done and say previous error (gjournal cannot clear metadata
on ad3s1a: operation not permitted). and -v return no extra log.
i don't know why i can not do any thing in fixit mode:(
is this a true procedure? i mean maybe i should do any thing else because
freebsd handbook set journaling for user partition in single user mode not
in fixit mode. i test it and it works well, but for root partition i can
not do the same because root partition can not be unmount in single user
mode.
any hints or comments are really appreciated.
thanks in advance
Hi,
i remember having similar error messages with glabel some years ago.
The solution was found in "man 4 geom" in section DIAGNOSTICS:
I had to set "kern.geom.debugflags=0x10" to enable the "foot shooting" mode.
Maybe this could help you too?
For certain values of "help". :)
If geom won't let you write to part of a disk, it's because it thinks
that part of the disk is already in use, usually by a mounted
filesystem. Overwriting part of a filesystem is not guaranteed to lose
data. But why take the chance?
Better to boot from mfsBSD (http://mfsbsd.vx.sk/). Possibly better yet
to use SUJ, which can be enabled with tunefs with the root partition
mounted read-only in single user mode. SUJ has its own problems,
though.
