disk remirror

[Jannik]

hey,
I have a rp7410 server with mirror vg00. One of the disks had an error, and some of the PE change to stale.
What is the easy way to get it to remirror current to stale?
# lvchange
is probably the command i need but what parameters and in what order?
Is there a guide out there :-) ?

Hi Jannik,

lvsync or vgsync will do the job.

Check out the Software Recovery Handbook:

Specifically you want Chapter 16 - Logical Volume Manager. It goes into details about how to replace disk drives. From the link below click on the "Open the Logical Volume Manager (LVM) chapter" link.

HI Jennik,

If the disk had a problem and you replaced it, then you would need to follow more than 'lvchange|vgchange' procedure. Search these forums with 'replace mirror disk' and you should get quite a few threads on it.

If you are sure that the disk is ok, then you would need to do

#vgsync vgxx

This will sync'up all the logical volumes in that volume group.

Hi Jannik,

I would tell you to know reasons that disks had errors. Probably hw problems?
If yes then work about an hw call.
If no hw problems on disk then just

# vgsync
