Hi, how I can deactivate encryption in DRBD resource?
I'm thinking to convert DRBD from primary/primary to active/passive how I need to modify the configuration files?
Based on your experiences, I have two HP ProLiant DL360 G5 with two HP Smart Array P400 (512 MB + battery) and Gigabit NIC are HP NC373i, how would you tune up the configuration file of DRBD?
This are mine /etc/drbd.d/ro.res
resource r0 { protocol C;
startup {
wfc-timeout 15;
degr-wfc-timeout 60;
become-primary-on both;
}
net {
max-buffers 8000;
max-epoch-size 8000;
sndbuf-size 512k;
cram-hmac-alg sha1;
shared-secret "******";
allow-two-primaries;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
after-sb-2pri disconnect;
}
syncer {
rate 150M;
}
on emu1 {
device /dev/drbd0;
disk /dev/cciss/c0d1p1;
address 192.168.50.1:7788;
meta-disk internal;
}
on emu2 {
device /dev/drbd0;
disk /dev/cciss/c0d1p1;
address 192.168.50.2:7788;
meta-disk internal;
}
}
And this are mine /etc/drbd.d/global_common.conf
global { usage-count no;
# minor-count dialog-refresh disable-ip-verification
}
common {
protocol C;
handlers {
pri-on-incon-degr "/usr/lib/drbd/notify-pri-on-incon-degr.sh; /usr/lib/drbd/notify-emergency-reboot.sh; echo b > /proc/sysrq-trigger ; reboot -f";
pri-lost-after-sb "/usr/lib/drbd/notify-pri-lost-after-sb.sh; /usr/lib/drbd/notify-emergency-reboot.sh; echo b > /proc/sysrq-trigger ; reboot -f";
local-io-error "/usr/lib/drbd/notify-io-error.sh; /usr/lib/drbd/notify-emergency-shutdown.sh; echo o > /proc/sysrq-trigger ; halt -f";
# fence-peer "/usr/lib/drbd/crm-fence-peer.sh";

# after-resync-target /usr/lib/drbd/unsnapshot-resync-target-lvm.sh;
}
startup {
# wfc-timeout degr-wfc-timeout outdated-wfc-timeout wait-after-sb;
}
disk {
# on-io-error fencing use-bmbv no-disk-barrier no-disk-flushes
# no-disk-drain no-md-flushes max-bio-bvecs
}
net {
# sndâ€buf-size rcvbuf-size timeout connect-int ping-int ping-timeout max-buffers
# max-epoch-size ko-count allow-two-primaries cram-hmac-alg shared-secret
# after-sb-0pri after-sb-1pri after-sb-2pri data-integrity-alg no-tcp-cork
}
syncer {
# rate after al-extents use-rle cpu-mask verify-alg csums-alg
}
}
Thank you very much!
