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


I have successfully deployed the tertiary stacked node.

[root at n1 ~]# cat /proc/drbd
version: 8.3.13 (api:88/proto:86-96)
GIT-hash: 83ca112086600faacab2f157bc5a9324f7bd7f77 build by

Now I am formatting my DRBD Disk but get this error:

[root at n1 ~]# mkfs.ext3 /dev/drbd0
mke2fs 1.39 (29-May-2006)
/dev/drbd0 is apparently in use by the system; will not make a filesystem

Anyone please guide me in this regard

Best Regards,

Salman Riaz Siddiqui.
