#4811 max number of hard disks
I have a system ( Debian Linux 8 ) with 9 Hard Disks attached to it, but webmin shows up just 8 of them .
This is the outout of the lsscsi command :
root@backup:~# lsscsi
[0:0:0:0] disk ATA WDC WD20EADS-00S 5G04 /dev/sda
[1:0:0:0] disk ATA WDC WD20EADS-00S 5G04 /dev/sdb
[2:0:0:0] disk ATA WDC WD20EADS-00S 5G04 /dev/sdc
[3:0:0:0] disk ATA WDC WD20EADS-00S 5G04 /dev/sdd
[4:0:0:0] disk ATA WDC WD20EZRX-00D 0A80 /dev/sde
[5:0:0:0] disk ATA WDC WD20EZRX-00D 0A80 /dev/sdf
[6:0:0:0] disk ATA WDC WD3200AAJS-0 3E01 /dev/sdg
[7:0:0:0] disk ATA WDC WD20EARS-00J 0A80 /dev/sdh
[8:0:0:0] disk ATA WDC WD20EZRX-00D 0A80 /dev/sdi
[10:0:0:0] cd/dvd HL-DT-ST BD-RE GGW-H20L YL05 /dev/sr0

Attached goes the screen of webmin in the same system :
Do the disks after the 8th show up in the /proc/partitions file?
This file have zero bytes .

It's a special file that appears to be zero length, but isn't really. You can see the contents by running
cat /proc/partitionsthis is the output :
root@backup:~# cat /proc/partitions

It looks like
/proc/partitions(which is Webmin's source of which disks exist) is missing some, like/dev/sde. That explains why they aren't showing up.
