After using LUN masking and zoning to make sure that hosts didn't access other hosts data space, I find myself with lost volumes on some of the hosts. Since I didn't remove them before making the changes, I am now stuck with the following; # lvscan /dev/sda: read failed after 0 of 4096 at 0: Input/output error ACTIVE '/dev/VolGroup03/web' [475.62 GB] inherit # vgscan Reading all physical volumes. This may take a while... /dev/sda: read failed after 0 of 4096 at 0: Input/output error /dev/sda: read failed after 0 of 4096 at 1073676288: Input/output error /dev/sda: read failed after 0 of 4096 at 0: Input/output error Found volume group "VolGroup03" using metadata type lvm2 # pvscan /dev/sda: read failed after 0 of 4096 at 0: Input/output error /dev/sda: read failed after 0 of 4096 at 1073676288: Input/output error /dev/sda: read failed after 0 of 4096 at 0: Input/output error PV /dev/sdb VG VolGroup03 lvm2 [475.62 GB / 0 free] Total: 1 [475.62 GB] / in use: 1 [475.62 GB] / in no VG: 0 [0 ] With the changes, /dev/sda and /dev/sdc (which doesn't show anymore) no longer exists. How can I safely remove the sda references? Mike -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
