Is there a good reason to have them all on separate disks? Have you considered LVM? It's great for attaching sets of disks, and when you decide to add more later it's just a few simple commands.

I dont take the good explain.

It's for a private parking My system is a ubuntu with scsi Disksbay
All cam are hight def and they ars in Record Mode
We must save 3 month of records

The disksbay is attached like this (and i can't change it)

3 x 1Tb RAID 5 --> SDC1 --> Monitor1
3 x 1Tb RAID 5 --> SDD1 --> Monitor2
3 x 1Tb RAID 5 --> SDE1 --> Monitor3
3 x 1Tb RAID 5 --> SDF1 --> Monitor4

LVM is a method of pooling the disks to appear as 1. If you could reformat/arrange the volumes into an LVM then your 4 1 terabyte raids would show up as one big 16 terabyte disk.

Warning: LVM is not for the faint of heart, or for the boot partition. Google LVM2 in your native language and see if it's something you could do/would want to do.

Meanwhile, my regex is too rusty to argue with the other lines, but you'll want to change line 3 to

Code: Select all

$df = shell_exec( 'df --total /usr/share/zoneminder/events/1 /usr/share/zoneminder/events/2 /usr/share/zoneminder/events/3 /usr/share/zoneminder/events/4' );

It's a start.

I know But the System Administrator don't want change to LVM
