Thanks Luca Fornasari for your answer
Please let me tell you that:
1- I use direct conection for DRBD (NIC to NIC)
2-I don't have changed my sysctl.conf file, this file are as the original
instalation.
3- Making tests, first I change the directive net data-integrity-alg sha1 to
md5, and after of approximately one hour DRBD shows errors
4- After, i change the bond RR to active-backup, and DRBD shows errors again
after of approximately one hour
5- About of fencing, is right that I need it, "but please for now i need
help to resolve my problem of DRBD replication"
*So any help or clue to solve my problem is welcome*
Take bonding out of the picture entirely for now. When dealing with
problems, the first thing you do is take as many variables out of the
equation you can.
If you are on 8.3.10, or 8.3.13, upgrade to 8.3.15. Perhaps your issue
was resolved in an update.
With fencing, you would not have avoided the original problem, but you
would have protected the setup from a split-brain and would still be
operating, albeit in a degraded state.
*Questions:*
1-Do you think that install DRBD 8.4.3 will solve my problem? (i can install
it from the source)
8.3 to 8.4 was a massive jump. Stay in 8.3.x for now.
2- Any other idea for solve my problem?
3- Or anyone that uses DRBD 8.3.13 without the directive "net
data-integrity-alg" , and after a long time (for example one month or more),
when execute by CLI "drbdadm verify <Resource-Name>" not shows errors of
DRBD ???
*I will be extremely grateful to you or anyone who can help me !!!*
Best regards
Cesar
If you are needing to fix this immediately, then I would call Linbit and
ask for (paid) support. They will fix this better than anyone else can.
If you can't wait until Monday, Hastexo is available for (paid) support
24/7. They are also extremely capable with DRBD and HA support.
