NIM - "...the resource is currently allocated for client use" - er, NO it's not!

When adding software to a lpp_source:

0042-001 nim: processing error encountered on "master":

   0042-061 m_rmpdir: the "lpp_aix710TL04SP02" resource is currently

        allocated for client use

Even lsnim is telling me that the resource is still allocated, somewhere, because alloc_count is set to 1.

# lsnim -Fl lpp_aix710TL04SP02
lpp_aix710TL04SP02:
   id          = 1465831650
   class       = resources
   type        = lpp_source
   arch        = power
   Rstate      = ready for use
   prev_state  = unavailable for use
   location    = /export/lpp_source/aix71/aix710TL04SP02
   simages     = yes
   alloc_count = 2
   server      = master

How to mount LVM partitions from rescue mode (Fedora/CentOS/RedHat)

Boot your rescue media.
Scan for volume groups:

# lvm vgscan -v

Activate all volume groups:

# lvm vgchange -a y

List logical volumes:

# lvm lvs –all

With this information, and the volumes activated, you should be able to mount the volumes:

# mount /dev/volumegroup/logicalvolume /mountpoint

Resize ext4 lv/filesystem

lvextend -L +SIZE /dev/mapper/lv_name

resize2fs /dev/mapper/lv_name

Where SIZE is:

XXXM, for Megabytes
XXXG, for Gigabytes
etc..

and lv_name is the name of the logical volume, obtained with the "lvs" command.
