perfSONAR User Q&A and Other Discussion

[Kathy Benninger <>]

Hi Aaron,

Available storage devices are:
  one ~220GB SSD
  two 2TB disks
I told RedHat to use all the storage for perfSONAR.

RedHat configured:
  ~64GB (about 1/3 of the SSD) for /, /dev/shm, and /boot
  ~4TB for /home
resulting in database and log storage all configured onto a portion of the 
(relatively) small SSD.  The software RAID is gone, with all 4TB allocated 
to /home.

In detail, I ended up with:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/vg_dhcp145c-lv_root
                      51606140   2098480  46886220   5% /
tmpfs                 12298336         0  12298336   0% /dev/shm
/dev/sda1               495844     37930    432314   9% /boot
/dev/mapper/vg_dhcp145c-lv_home
                     4012173384    199824 3808166840   1% /home

When what I really want is what I had before:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda2            119031092   1906408 110980628   2% /
/dev/sda6              4956284    141252   4559200   4% /tmp
/dev/md0             1892332848  61523772 1733133480   4% /var
/dev/sda3             49594228   2110072  44924200   5% /home
/dev/sda1               988088     46128    890956   5% /boot
tmpfs                  1548864         0   1548864   0% /dev/shm

I'm open to suggestions on how to proceed.  ideas other than removing the 
SSD from the perfSONAR device list and just doing a 4TB install on the two 
disks?

Kathy
