Lvextend: could not re-synchonize logical volume

[AwadheshPandey]

Hello Experts,
I am getting following error when do a lvextend on a lvol,
Lvextend: could not re-synchonize stale partions of the logical volume,
I/O Error
lvextend: could not re-synchronize logical volume.

This volume group has 4 lvols and three are extended successfully, I have replaced disks, diskstatios, terminator, cable and scsi controller.
No threads link please, i had checked all of them and do a lot of work on this.

Thanks in Advance

Awadesh,

How good are your Back-Up's ? How about starting with a fresh new filesystem.

Hi Awadhesh,

Can you do a # dd if=/dev/rdsk/cxxxxxx of=/dev/null bs=1024k on the source disk ?

It could be due to bad disk.

Hi

I agree with Bob if you have a good backup then you can create and new filesystem and try to sync it again.

Your throwing hardware at the problem essentially eliminated all chance of you recovering. You probably missed step 0 of any LVOL change. Do an lvdisplay -v for all LVOL's are make sure that all extents are "current".

lvdisplay -v /dev/vgDL/lvolHome | grep -i stale produce following o/p.

00016 /dev/dsk/c2t2d0 01891 current /dev/dsk/c5t14d0 02516 stale
00199 /dev/dsk/c2t2d0 02074 current /dev/dsk/c5t14d0 02699 stale

Yes, I know but the point is you should have done this before ever doing an lvextend. That's part of the LVM 101 curriculum.

What will be impact on system if we will continue our system on this state.

If you are lucky then
lvsync /dev/vgDL/lvolHome
