I was using yast2 to remove iscsi volume and the following error appeared on the desktop:
Failure occurred during following action:
Deleting logical volume /dev/vollinea00/logvol_iscsi_01
System error code was: -4015
/sbin/lvremove Âf Â/dev/vollinea00/logvol_iscsi_01Â:
CanÂt remove open logical volume Âlogvol_iscsi_01Â
WhatÂs the meaning of ÂSystem error code was: -4015Â?
Sles11SP1 and all current updates installed.
