Hi, During established DRBD+Pacemaker, I met the problem with the following error in node2. I've googled a lot information, but nothing helped. In another production environment, everything works. DRBD+Pacemaker, failover OK.
Could you please help me out? app-ebs02:/dev/mapper # lvcreate -n ipwvol -L 50G ipwdg WARNING: Locking disabled. Be careful! This could corrupt your metadata. device-mapper: reload ioctl failed: Invalid argument Aborting. Failed to activate new LV to wipe the start of it. app-ebs02:/dev/mapper # dmesg |grep -i "device" [375349.283710] device-mapper: table: 253:0: linear: dm-linear: Device lookup failed [375349.283713] device-mapper: ioctl: error adding target to table Is that because the hard-disk is broken? Thank you in advance. Best Regards, YUAN LUO
