[DRBD-user] sync speed issue

[R.B. (Rick)]

Hi guys,

my two drbd 0.6.10 on my fedora fc1 sync very slow:

[root at proxynode1 root]# cat /proc/drbd
version: 0.6.10 (api:64/proto:62)

0: cs:SyncingAll st:Primary/Secondary ns:18837284 nr:0 dw:12 dr:18837385 
pe:43 ua:0
         [===>................] sync'ed: 17.0% (28613/34451)M
         finish: 0:42:50h speed: 11,669 (11,430) K/sec

Those two NICs are 100Mbit capable...i've tried with crossover cable and 
also with a switch but without success... any ideas?
Why drdb startup script waits for complete sync? In this case my linux box 
doesn't complete startup procedure... how can avoid this?

Thanks again

Riccardo


This is my drbd.conf:

resource drbd0 {
protocol = C
fsckcmd  = fsck.ext3 -p -y
disk {
  do-panic
disk-size = 35278540k
}

  net {
     sync-min    = 500k
     sync-max    = 100M    # maximal average syncer bandwidth
     tl-size     = 5000  # transfer log size, ensures strict write ordering
     timeout     = 60    # unit: 0.1 seconds
     connect-int = 10    # unit: seconds
     ping-int    = 10    # unit: seconds
     ko-count    = 4     # if
   }

   on proxynode1 {
     device  = /dev/nb0
     disk    = /dev/sdb1
     address = 172.32.254.1
     port    = 7788
   }

   on proxynode2 {
     device  = /dev/nb0
     disk    = /dev/sdb1
     address = 172.32.254.2
     port    = 7788
   }
}

Any ideas?

Thanks

Riccardo
