1) Run a pre-script. The pre-script uses lvsplit on logical volumes that are mirrored and have to stay up, which will lvolxb. Then the script mount lvolxb under temporary points.
2) Start backup from OMNIBACk which will pick up mounted lvolxb.
3) Run a post-script to unmount the temporary mount points, and use lvmerge to start the mirroring.
This procedure has been working well until we got an error message recently while running the pre-script. The error message is like "lvsplit: There aren't enough mirros to make a split copy: /dev/vg01/lvol8". We have mirrored logical volumes from /u01 to /u08. lvsplit only failed on the last one, which is /u08.
Any suggestions?
Thank you very much in advance.

Re: lvsplit: There aren't enough mirros to make a split copy
it looks to me like the mirror disk has failed OR some thing wrong with the LVM mirroring. check lvdisplay -v /dev/vgxx/lvolx and see whether you can all the physical extents of the LV are in sync. try spliting the mirror manually and see how it goes.
If the lvdisplay shows "stale" PEs, then check for the mirror disk and see it is working normal by doing pvdisplay and diskinfo commands.
hope this helps you ..

Re: lvsplit: There aren't enough mirros to make a split copy
When doing an lvdisplay for that logical volume does it show 0 as mirrored copies , which means it is already split. So remerge it back and try again.
you can check the failed logical volume, check for errors in syslog / try doing a dd of logical volume to /dev/null see if o.k
