Red Hat Bugzilla – Bug 441323
fence_scsi gets errors in device list with multipath arrays
Last modified: 2009-04-16 18:24:58 EDT
When using a active/passive array, fence_scsi will get errors in the list of
devices. This will cause fencing to fail.
The problem appears to be that the command we use to get a list of devices (vgs)
will scan all devices, including the passive path. This generates errors to
stderr, and these errors get including in the list of devices.
Solution is to redirect stderr to /dev/null as part of this command. We already
do this in the scsi_reserve init script.
Fixed in RHEL5 branch.
