Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


Actually we are using an external meta-data disk.
with drbd 0.7.13 on top of  xfs & lvm.Our
problem only in this disk size range   1.2TB ~ 1.5TB
we can only encounter this issue on that range
but 2tb is okey(Very unusual)..  Is this something to do with the disk 
health?



thanks,
francism

> What does this means?

quoting the example drbd.conf file

# NOTE that if you do not have some dedicated partition to use for
# the meta-data, you may use 'internal' meta-data.
#
# THIS HOWEVER WILL DESTROY THE LAST 128M
# OF THE LOWER LEVEL DEVICE.
#
# So you better make sure you shrink the filesystem by 128M FIRST!
# or by 132M just to be sure... :)

or, put in an other way:
 you do mkfs on /dev/drbd0,
 not on /some/lower/level/device

why? try to
 dd if=/dev/sda1 of=/dev/fd0
 mount /dev/fd0 /mnt/wont_work
