[Linux-cluster] Howto? Remove volumes



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
