     1.4 +IMPORTANT! DATA LOSS POTENTIAL!
     1.5 +-------------------------------
     1.6 +
     1.7 +It is important that no changes be made to the virtual disk manager through
     1.8 +the command line while the web interface is running!
     1.9 +
    1.10 +If you use the web interface at all, it is NOT safe to call:
    1.11 +xenctl partitions add
    1.12 +xenctl vd create
    1.13 +xenctl vd delete
    1.14 +xenctl vd refresh
    1.15 +
    1.16 +Your changes will likely be lost, or the virtual disks left in an
    1.17 +inconsistent state, or data on them corrupted or erased.
    1.18 +
    1.19 +Other xenctl functions do not modify VDM state and are therefore safe,
    1.20 +e.g. it's okay to do domain control from the command line if the web
    1.21 +interface is running.
