Review the datastore configuration after initial deployment to determine if you have enough drive space to accommodate the needs of your enterprise. As an example, this topic reviews the datastore configuration of the PacketDB on the Log Decoder host after you first deploy it from an Open Virtualization Archive (OVA) file.

Initial Space Allocated to PacketDB

The allocated space for the PacketDB is very small (about 98 GB). The following Security Analytics Explore view example shows the size of the PacketDB after you initially deploy it from OVA.

Initial Database Size

By default, the database size is set to 95% of the size of file system on which the database resides. SSH to the Log Decoder host and enter the df -k command string to view the files system and its size.

[root@LogDecoderGM ~1}# df -k

The following output is an example of the information that this command strings returns.

/dev/mapper/VolGroup01-logcoll

67076096      42652   67033444    1% /var/netwitness/logcollector

/dev/mapper/VolGroup01-packetdb

108994564      37152  108957412    1% /var/netwitness/logdecoder/packetdb

PacketDB Mount Point

The database is mounted on the packetdb logical volume in VolGroup01 volume group. VolGroup01 and this is where you start your expansion planning for the file system.

Initial Status of VolGroup01

  1. SSH to the Log Decoder host.
  2. Enter the lvs (Logical Volumes Show) command string to determine which logical volumes are grouped in VolGroup1.

    [root@LogDecoderGM ~1}# lvs VolGroup01.

    The following output is an example of the information that this command strings returns.

    LV               VG          Attr          LSize    Pool Origin Data%  Move Log Cpy%Sync Convert

    decoroot   VolGroup01  -wi-ao---  20.00g

    index      VolGroup01  -wi-ao---  10.00g

    logcoll    VolGroup01  -wi-ao---  64.00g

    metadb      VolGroup01  -wi-ao---  44.00g

    packetdb   VolGroup01  -wi-ao--- 104.00g

    sessiondb  VolGroup01  -wi-ao---  30.00g

  3. Enter the pvs (Physical Volumes Show) command string to determine which physical volumes belong to a specific group.

    [root@LogDecoderGM ~1}# pvs

    The following output is an example of the information that this command strings returns.

    PV             VG         Fmt  Attr    PSize    PFree

    /dev/sdb1  VolGroup00 lvm2 a--   32.00g      0

    /dev/sdc1  VolGroup01 lvm2 a--   104.00g

    /dev/sdd1  VolGroup01 lvm2 a--   168.00g  0

  4. Enter the vgs (Volume Groups Show) command string to display the  total size of specific volume group.

    [root@LogDecoderGM ~1}# vgs

    The following output is an example of the information that this command strings returns.

    VG                #PV #LV #SN Attr    VSize     VFree

    VolGroup00   l     7   0  wz--n-  32.00g       0

    VolGroup01   2     6   0  wz--n-  32.00g       0
