I have removed the line size 9380 in drbd.conf of active SC and rebooted it.
After that when DRBD is brought up on Standby SC, Handshake was successful, but pdsk( DUnknown -> Diskless ).
Can some one help me resolving this issue?
Excerpts from drbd.conf:
disk {
on-io-error detach;
}
on Sc1 {
device /dev/drbd0;
disk /dev/tffsb4;
address 10.19.17.1:7789;

}
on Sc2 {
device /dev/drbd0;
disk /dev/tffsb4;
address 10.19.18.1:7789;
meta-disk internal;
}

Subject: [DRBD-user] Upgrade DRBD-8.0.6 to DRBD-8.0.16
Hi,
Our current system is running DRBD-8.0.6 on 2 boards, One of the baords is active and the other board is standby.
DRBD is configured with meta-disk set as internal, port 7789, protocol C, size 9380. Excerpts attached at the end.
To minimize outage by resetting both boards, we would like to upgrade and bring up standby board on DRBD-8.0.16 first. My attempts are not successful so far.
Things modified to match DRBD-8.0.16:
In drbd.conf file size is modified as "size 9380K"
All other entries are kept same as in DRBD-8.0.6
Issues:
When drbd is started on standby drbdstatus shows
0: cs:WFConnection st:Secondary/Unknown ds:UpToDate/DUnknown C r---
And Primary does not detect DRBD on standby board.
0: cs:WFConnection st:Primary/Unknown ds:UpToDate/DUnknown C r---
Questions:
1. Is DRBD-8.0.16 backward compatible with DRBD-8.0.6?
2. Why there is no communication between DRBD-8.0.6 and DRBD-8.0.16?
3. Can any one list all the changes one must do to upgrade DRBD version on a redundant setup (standby first and then active)?
Excerpts from drbd.conf of DRBD8.0.6:
disk {
on-io-error detach;
size 9380;
}
on Sc1 {
device /dev/drbd0;
disk /dev/tffsb4;
address 10.19.17.1:7789;
meta-disk internal;
}
on Sc2 {
device /dev/drbd0;
disk /dev/tffsb4;
address 10.19.18.1:7789;
meta-disk internal;
}
Please do the needful,
Thanks and Regards,
LAK
