+=== Removing a host from nebulous permanently ===
+
+If the RAID fails on the data partition and we lose the data from that partition, we need to do the following in the nebulous database:
+
+ 1. Remove the entry in the {{{mountedvol}}} table (should be auto-removed by {{{nebdiskd}}}):
+   * {{{DELETE FROM mountedvol WHERE vol_id = XX;}}}
+ 1. Convert the entry in the {{{volume}}} table to point to a dummy location:
+   * {{{UPDATE volume SET name = 'ippNNN.0X', path = '/data/ippNNN.0X/nebulous', mountpoint = '/data/ippNNN.0X' WHERE vol_id = XX;}}
+ 1. Add the new volume:
+   * {{{neb-voladd --vname ippXXX.0 --vhost ippXXX --uri file:///data/ippXXX.0/nebulous --mountpoint /data/ippXXX.0 --db nebulous --user nebulous --pass XXX}}}
+   * {{{neb-voladm --vname ippXXX.0 --cab_id X --db nebulous --user nebulous --pass XXX}}}
