Map/Mount Volume Group Folder to Volume Group Folder???

Led Zappa · 09-17-2013, 06:01 PM

I am trying to backup FreePBX, but it will only back up to it's specified path on the local disk. I have another partition/volume group with Gigabytes in free space. I want to point/mount that space to the default location for PBX which is on the root partition/VG. Is that possible?

This is also on mirrored drives.

So, essentially I want to have /var/lib/asterisk/backups on the root partition/VG pointing to /backups on the /home partition/VG

Code:

[root@localhost asterisk]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup-lv_root
                       50G   29G   19G  62% /
tmpfs                 2.0G     0  2.0G   0% /dev/shm

/dev/mapper/VolGroup-lv_home
                      404G  444M  383G   1% /home

Code:

[root@localhost asterisk]# fdisk -l

Would a symlink work?

As a newbie, I don't know, but it doesn't seem like it. I got the idea from a support page for PBX which said you could mount a USB Drive and mount the usb to the root path where FreePBX would try and point files, but I can't figure out how to do the same thing with a partition/VG. I don't even know if those above are true partitions or Volume Groups. I'm reading up as much as I can.

If I can as root on the local system copy a file pointed to /var/lib/asterisk/backups and the data would actually end up in /home/backups I believe it will work. I don't care how I get there.

Okay; then try this

Code:

 ln -s /home/backups /var/lib/asterisk/backups

Note that /var/lib/asterisk/backups must not exist and /home/backups must exist

Verify with...

Code:

touch /var/lib/asterisk/backups/TEST.txt
ls -l /home/backups

--C

Thanks for your reply custangro, but unfortunately I won't be able to test the solution as the company I was working for shut their doors last week

On to bigger and better things I guess.
