128MB is needed for each device. So 4 (0,1,2,3) times 128MB makes 512MB and not 360MB. See also manpage:
meta-disk device [index]
internal means, that the last 128 MB of the lower device are
used to store the meta-data. You must not use [index] with
internal.
You can use a single block device to store meta-data of multiple
DRBD devices. E.g. use meta-disk /dev/hde6[0]; and meta-disk
/dev/hde6[1]; for two different resources. In this case the
meta-disk would need to be at least 256 MB in size.

Betreff: [DRBD-user] Metadevice question
Hi,
in the http://wiki.linux-ha.org/DRBD_2fQuickStart07 I founded:
"Currently DRBD meta-data reserves 128MB, regardless of actual physical data
storage. This allows for a maximum storage size of a single DRBD device of
approximatly 4TB. "
I need 5 drbd devices. For the first and second no problem.
For the other devices I received:
Starting DRBD resources: [ d0 d1 d2 ioctl(,SET_DISK_CONFIG,) failed: Invalid
argument
Meta device too small.
cmd /sbin/drbdsetup /dev/drbd3 disk /dev/hda10 /dev/hda16 3 --on-io-error=detach
failed!
where: hda10 is 10Gb and hda16 is 360Mb and drbd version is 0.7.10 for kernel
2.4.27-2-386 (debian)
Where is the problem?
Thanks in advance.
A. Pietrobono
