lvxtend - Problem after change of root-mirror

[AnSi53]

I know, it's daily business, but
lvextend: couldn't re-synch stale partitions of the logical volumes: I/O error

It happens only on /dev/vg00/lvol1 , 2 and 3
Other LVs can be extended / mirrored.

I did already lvsync on these lvols.
Everything seems to be fine
pvcreate ....
vgextend ...
mkboot
but no synchronize on lvol1 , 2 and 3!!!
grrrrrrrrrrr
Any ideas?
Reboot without mirror? Maybe fsck helps?
Regards

Hi Andreas:

It appears that you have a bad disk! Follow the guidelines for replacement found here:

Regards!

Hmmm, you would say, the new ( used in another system before ) disk, the replacement of the old mirror-disk, is damaged too?? hmmmm

I tried a dd, there where no errors.

pfffft

recreate mirror and force it while doing pvcreate.

pvcreate -fB /dev/rdsk/CXXtYYdZZ
mkboot ...
vgextend /dev/vg00 /dev/dsk/...

Make sure that you mirror lvol1, 2 and 3 first and then mirror remaining logical volumes.

Hi,

did you vgreduce the disk before vgextend the new one?
What does "strings /etc/lvmtab" and "vgdisplay -v vg00" give?

If dd works, there could be a config problem.

Good morning,

I did all the *normal* tasks and took care of the rules to mirror a root-disk.

Ok, I will put a new VG on the disk and see what happen........

I'll give you response!

ok, when you pvcreate your new disk try :

pvcreate -f -B /dev/rdsk/c0t5d0

I was hopeful, cause I didn't try both options before.
But ....... grrrrrr same message while lvextend.
lvlnboot gives now both disks as Boot disk.
That was option -B.
Remember, the other lvols can be mirrored, without problems! Is there a problem with the original lvol1 2 and 3 ?? hmmmm.

Did you try with vgsync vg00?

[AnSi53]

I did that all before, reading man-pages and .. and .. and ....

Here the reslut in the attachment!

do you try to unmirror with lvreduce -m 0 all lvs and then remake mirror.

One of those two disks may have some bad blocks. To identify the problem you may try with cstm -> map -> select path (path of disk) -> info -> li
check both disks. If you cannot use stm or you cannot find errors there try to write on read from whole disk with dd command

dd if=/dev/dsk/c0t5d0 of=/dev/null bs=128k

if no I/O error found, try with the other disk

dd if=/dev/dsk/c0t5d0 of=/dev/null bs=128k

Hope you will find "broken" disk and you may need to replace it.

Problem found!
Sh ....t happens!

dd read error: I/O error on the orig root-disk. Well, mirror-disk gone, orig root problems - have a nice day ......

Thanks to all
