[DRBD-user] DRBD Sync stalls

[Димитър Бойн]

Thanks for the hints!
I have another DRBD pair configured with the same hardware and cloned OS images etc which sync just fine…
All server nodes are connected to the same switch :-(
 
Any ideas?
 
Here is the config:
cat /etc/sysctl.conf | grep net
 
net.ipv4.ip_forward=0
net.ipv4.conf.all.accept_source_route = 0
net.ipv4.conf.lo.accept_source_route = 0
net.ipv4.conf.eth0.accept_source_route = 0
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.lo.rp_filter = 1
net.ipv4.conf.eth0.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.lo.accept_redirects = 0
net.ipv4.conf.eth0.accept_redirects = 0
net.ipv4.conf.default.accept_redirects = 0
net.ipv4.conf.all.accept_source_route = 0
net.ipv4.conf.lo.accept_source_route = 0
net.ipv4.conf.eth0.accept_source_route = 0
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.conf.all.rp_filter = 1
net.ipv4.conf.lo.rp_filter = 1
net.ipv4.conf.eth0.rp_filter = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.all.accept_redirects = 0
net.ipv4.conf.lo.accept_redirects = 0
net.ipv4.conf.eth0.accept_redirects = 0
net.ipv4.conf.default.accept_redirects = 0
net.ipv4.tcp_fin_timeout = 15
net.ipv4.tcp_keepalive_time = 1800
net.ipv4.tcp_window_scaling = 0
net.ipv4.tcp_sack = 0
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_syncookies = 1
net.ipv4.icmp_echo_ignore_broadcasts = 1
net.ipv4.icmp_ignore_bogus_error_responses = 1
net.ipv4.tcp_max_syn_backlog = 1280
net.ipv4.tcp_max_tw_buckets = 1440000
net.ipv4.ip_local_port_range = 16384 65536

Hi all,



If seen this behaviour also. 

1) DRBD is full syncing

2) after a period of time the sync is stalled

3) after again a little while the whole machine is frozen. (only the source machine)



my setup

openSUSE 11.1

drbd 8.3.1 (however the same, with 8.2)

Both machines where connected to the same 1 gig switch. (simple 1 gig switch for staging purposes)



My impression was it was HW related. since a was installing three clusters and only one of them was showing this behavior. The machine involved was a Fujisu Siemens server TX200



mfg,



jeroen

There have been two answers.   What would be the best way to troubleshoot? Any way to troubleshoot?     have a look at my sig ;)
