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 –f ‘/dev/vollinea00/logvol\_iscsi\_01’: Can’t remove open logical volume “logvol\_iscsi\_01” What’s the meaning of “System error code was: -4015”? Sles11SP1 and all current updates installed. ---

[QUOTE=williamhanna;2947]I Can’t remove open logical volume “logvol\_iscsi\_01” … What’s the meaning of “System error code was: -4015”? [/QUOTE] As the message a little under it indicates… the system/a process still has an active/open LVM connection to the volume you are trying to delete. Have you ensured all mounts to the volume have been unmounted and checked with ‘lsof /dev/vollinea00/logvol\_iscsi\_01’ what might me keeping a connection to the volume open? If that’s not clear, try rebooting the system (after having made sure there are not scripts/mount points set anymore) and deleting the volume after the reboot. -Willem ---

It seems that “System error was: -4015” is a generic yast error message, wich means the lvm is not free to be deleted… Thanks, William
