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

Thanks for the reply,

My DRBD:

server:~ # cat /proc/drbd
version: 0.7.11 (api:77/proto:74)
SVN Revision: 1807 build by root at server, 2005-08-08 16:25:00

server:~ # modinfo /lib/modules/2.6.5-override-smp/drbd.ko
parm:           disable_io_hints:Necessary if the loopback network device is used for DRBD (bool)
parm:           minor_count:Maximum number of drbd devices (1-255) (int)
parm:           use_nbd_major:DEPRECATED! use nbd device major nr (43) instead of the default 147 (bool)

depends:
vermagic:       2.6.5-7.191-smp SMP gcc-3.3


SuSE DRBD:

server:~ # modinfo /lib/modules/2.6.5-7.193-smp/extra/drbd.ko
parm:           disable_io_hints:Necessary if the loopback network device is used for DRBD (bool)
parm:           minor_count:Maximum number of drbd devices (1-255) (int)
parm:           use_nbd_major:DEPRECATED! use nbd device major nr (43) instead of the default 147 (bool)

depends:
supported:      yes
vermagic:       2.6.5-7.193-smp SMP gcc-3.3

It does appear that I am using the DRBD I intended to use.  I am planning to try SuSE kernel 2.6.5-7.201-smp and DRBD v0.7.13.  I will report back.

Thanks,
