Hi

This error confirms, that the lv, lv_ora, is used by some other process.

#fuser -u /

Close the sessions/process shown by fuser. u can add k switch, and force fully kill the process.

#fuser -ku /

And and u can do lvmerge

All the best

My lv_ora and lv_orab is unmounted.
How I can have some working program over them ?

You can use lsof |grep "lvname"

Tanks for all

I reboot server and problem DISAPPEAR.
But anyway how can I have some lv busy without mounting it ? Is there some flag insite LVM other then FS that cause this problem (Device busy)

Did u successfully lvsplit initially ?. Did it come out with some errors ?. Is there any monitoring tools (scripts ) present which does an lvdisplay or something like that ?.

Regds,

Yes lvsplit end without problem.
I have EMS but it's not a problem because other lv merge without problem.
The only reason for me is fs corruption.
