Error in lvdisplay : "Failed to recover mirror"

[Ian Killer_1]

Here's the output of my lvdisplay: Anyone seen this (truncated) error message on the last line before? All the PE's are CURRENT.

LV Name /dev/vg00/lvol6
VG Name /dev/vg00

You got LANG variable set to C, that's probably causing the weird output.

2 options ..
1) Ignore the message, it's harmless.
2) Run this to "unset" LANG.
# unset LANG

Hi Ian:

Check this document for a possible solution(TKB #KBRC00001165):

Sorry I couldn't assign any more points Shiju. I hit the link and get a "could not login" message, probably because I'm a european site user. Thanks.

Hi Ian:

No problem with the points. I am glad that your problem got resolved. The link pointed the same solution which S.K has given you.

This was the reason I 've given the TKB doc ID too. For checking the document, you go to the ITRC home page, select "search technical knowledge base" and select the "search by doc. ID" and submit the doc. ID there.

For your convenience I will post the same here:

PROBLEM
When LANG variable is set to C on my machine, the lvdisplay -v output adds the following line to the display:

Failed to recover mirror co "%s" has been forked to sy


RESOLUTION
Operating System - HP-UX
Version - 10.20
Hardware System - HP9000

This is a known problem with the lvdisplay command not working
properly when LANG is set to C.

The workaround is to:
unset LANG
or ignore the error message.

HTH,
Shiju
