Full Discussion: Bypass stale PE ?
Operating Systems HP-UX Bypass stale PE ? Post 302905473 by port43 on Wednesday 11th of June 2014 06:24:35 PM
Old 06-11-2014
So, I decided to unmirror everything and reorganize the logical volumes since some of them were spread over disks on the same controller or mirrored onto the same physical volume.

I got it to where I had all logical volumes on disks on one controller ie. each individual volume was completely on one disk on the 1/10/0 controller. I even put lvol5 (that had the stale PE) on it's own disk (c9t3d0) with nothing else on it. Everything was fine, all PE's were current. I then mirrored each LV to it's partner disk on the 0/10/0 controller ie. everything on c9t5d0 mirrored to c5t5d0 with no issue (lvol1 - lvol4, lvol6 - lvol8) but when I tried to mirror lvol5 from c9t3d0 to c5t3d0 I ran into the stale partition again, with the same PE's, and it's different disks this time:
Code:
# lvextend -m 1 /dev/vg00/lvol5 /dev/dsk/c5t3d0
The newly allocated mirrors are now being synchronized. This operation will
take some time. Please wait ....

lvextend: Couldn't re-synchronize stale partitions of the logical volume:
I/O error
lvextend: Couldn't resynchronize logical volume "/dev/vg00/lvol5".
# lvdisplay -v /dev/vg00/lvol5 | grep stale
LV Status                   available/stale
   00652 /dev/dsk/c9t3d0    00069 current  /dev/dsk/c5t3d0    00652 stale

I obviously do not understand how a stale PE on one disk can be the same stale PE on another.

Could it be as simple as a bad data in lvol5 where I need to fsck that file system before trying to mirror?

vxdestroy_lvmroot

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME

       vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group

SYNOPSIS

       vxdestroy_lvmroot [-v] [-b] lvm_root_disk

DESCRIPTION

       The  vxdestroy_lvmroot  command	tears  down  and removes the LVM volume group associated with the specified physical disk. This is done by
       removing the volumes in the volume group and then removing the volume group.

OPTIONS

       -b	 Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if  the  pri-
		 mary  boot  disk is not already set to this disk).  The alternate boot device remains unchanged.  If the -v option is also speci-
		 fied, the settings of the primary and alternate boot devices are displayed.

       -v	 Outputs verbose messages including a timestamp that indicates major operations being performed.

ARGUMENTS

       lvm_root_disk
	    Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group.

EXAMPLES

       This example shows the vxdestroy_lvmroot command invoked in its simpliest form:

       /etc/vx/bin/vxdestroy_lvmroot c5t1d0

       # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0
