Removal Instructions

Controller software

Offline migrations

In the source workload’s file system, under /boot, remove the ofx directory with its contents.

All live migrations

  • Kill these processes:

    • pkill -9 ofxcontrollerd

    • pkill -9 ofxjobexec

  • Remove the OFX controller rpm package:

    rpm -e ofxcontrollerd

  • In the source workload’s file system, remove the /usr/lib/ofx directory with its contents.

Block-level data transfer software

All block-level migrations

  1. Check if the driver is active:

    lsmod | grep blkwatch

    If the driver is still loaded in memory, the result should contain a line, similar to the following:

    blkwatch_7616  70924  0

  2. (Conditional) If the driver is still loaded, remove it from memory:

    rmmod blkwatch_7616

  3. Remove the driver from the boot sequence:

    blkconfig -u

  4. Remove the driver files by deleting the following directory with its contents:

    /lib/modules/[Kernel_Version]/Platespin

  5. Delete the following file:

    /etc/blkwatch.conf

LVM snapshots

Block-level migrations using LVM snapshots

  1. In the Jobs view, generate a Job Report for the failed job, then note the name of the snapshot.

  2. Remove the snapshot device by using the following command:

    lvremove snapshot_name
