Break disk mirror

Gene Laoyan — Sun, 19 Aug 2007 14:29:23 GMT

I need to stop/break the mirroring of my two disks. However, I wnat to do it via commandline.
Can someone give me good "Dummies" version on how to do this. I am writing a document/instructions so when we bring a new Unix admin on board I have docs on how to do this.

Thanks

Have a look at the 'lvsplit' and 'lvreduce' commands.

If you want to split a mirror, so that you can access the mirror separate from the original, then you should have a look at 'lvsplit'.

If you just want to stop mirroring altogether, you need to reduce the mirrored disk from the logical volume. For that you need to use 'lvreduce'. If you want to remove the now unused disk from the VG, then also look at the vgreduce command.

Have a look at the man pages for each command for specific syntax and options.

Just an fyi, I found this website: http://sl-workstations.web.cern.ch/sl-workstations/documentation/SAGpart-4.html

It seems to work on our test box.

Thanks
