Hi,

I'm not aware of any change. The only thing I did was to remove faulty drive
from md2 and put it back for resync (happened after reset of computer).

I cannot boot, during startup I get EVMS message it cannot find root and ask
me to provide valid  root block device. There is no
/dev/evms/lvm2/main/root
lvm2 is missing under evms

Using other evms volume I can boot (like /dev/evms/another-machine-root)

When I boot from USB stick RescueCd without doing doevms2 and then running
evms_activate and evmsn I can see the info I posted about last mail and can
work with evms.

I created evms exactly as described at this picture

Is there anyway I can have my data restored?

Thank you
