[DRBD-user] Limits to number of devices ?

[Denis PETIT]

Hi,

I'm trying to configure DRBD 0.7.21 on a kernel 2.6.16-2 (by
kernel-patch), on a Debian etch machine.

I'm succeeding at configuring /dev/drbd0 to /dev/drbd7, but for each
device i try to configure after /dev/drbd7, i have a :
"can not open /dev/drbd8: No such device or address"

I create with mknod the /dev/drbd i need and i'm there :
brw-rw---- 1 root disk 147,  0 2006-10-27 17:40 /dev/drbd0
brw-rw---- 1 root disk 147,  1 2006-10-27 17:40 /dev/drbd1
brw-rw---- 1 root disk 147, 10 2006-10-27 17:46 /dev/drbd10
brw-rw---- 1 root disk 147, 11 2006-10-27 17:46 /dev/drbd11
brw-rw---- 1 root disk 147, 12 2006-10-27 17:46 /dev/drbd12
brw-rw---- 1 root disk 147, 13 2006-10-27 17:46 /dev/drbd13
brw-rw---- 1 root disk 147, 14 2006-10-27 17:46 /dev/drbd14
brw-rw---- 1 root disk 147, 15 2006-10-27 17:46 /dev/drbd15
brw-rw---- 1 root disk 147,  2 2006-10-27 17:40 /dev/drbd2
brw-rw---- 1 root disk 147,  3 2006-10-27 17:40 /dev/drbd3
brw-rw---- 1 root disk 147,  4 2006-10-27 17:40 /dev/drbd4
brw-rw---- 1 root disk 147,  5 2006-10-27 17:40 /dev/drbd5
brw-rw---- 1 root disk 147,  6 2006-10-27 17:40 /dev/drbd6
brw-rw---- 1 root disk 147,  7 2006-10-27 17:40 /dev/drbd7
brw-rw---- 1 root disk 147,  8 2006-10-27 17:46 /dev/drbd8
brw-rw---- 1 root disk 147,  9 2006-10-27 17:46 /dev/drbd9

As i told, the 8 first devices seem to work very fine.
What's wrong with the next ones ?

Thanks in advance,
