Problem with the mirror
i changed the /dev/dsk/c5t1d0. After the changing, I have put on the mirror for all LV's again.
If I liked to mirror LV /dev/vg00/lvora10g, I get in LE only one mirror stale.
00342 /dev/dsk/c4t1d0 02646 current /dev/dsk/c5t1d0 00831 stale
The /dev/dsk/c5t1d0 is new disk.
I have run a fsck on /dev/vg00/lvora10g and there was okay. What can I do, to get this stale LE away?
Many thanks.
Yours sincerely
K. Jakob

Re: Problem with the mirror
stale extends refer to sometimes "Bad disk"
if you can ioscan , diskinfo and dd a drive normally than there is no hardware problem
Please check disk really bad by "dd"
sample :-
dd if=/dev/dsk/c2t1d0 of=/dev/null bs=128k

Re: Problem with the mirror
I mirrored the LV already several times, after beboot, after fsck, but the error is the same and on the same LE (00342 /dev/dsk/c4t1d0 current and the matching LE from c5t1d0 is stale).

Re: Problem with the mirror
thanks, but the vgrestore reports the message:
Cannot restore Physical Volumes /dev/dsk/c5t1d0,
Detach the PV ..
The c5t1d0 is already successfully integrated into other LV as a mirror.
Yours sincerely

Re: Problem with the mirror
seems as if the source PE is not being read,
try using dd to read the source disk.
might be that LE is not having some filesystem data in that,

Re: Problem with the mirror
instead of using another disk, you could test the drive by using /dev/null and /dev/zero like this:
read test:
# dd if=/dev/dsk/c5t1d0 of=/dev/null bs=256k
write test:
# dd if=/dev/zero of=/dev/dsk/c5t1d0 bs=256k
this way you can eliminate other error sources and the test goes much faster.
