[DRBD-user] 9.1.14 upgrade issue

[Nigel Phillips]

Akemi, 

Current values, reboot to new kernel, then values again in steps below. And yes, on reboot to newer kernel I still see 9.1.13 for /proc/drbd 

$ uname -r

Hi Nigel, 

Can you show the output from: 

$ find /lib/modules -name drbd.ko 

Also, if you boot kernel 4.18.0-425.19.2.el8_7 once again, what happens? Do you still see version: 9.1.13?

Akemi, 

Sorry syntax in email, did a copy and paste of the new update package name from the release email rather than from installed system package names. Actual system installed files are correct though, so the original problem does unfortunately still exist. 

$dnf list --installed | grep drbd 
drbd90-utils.x86_64 9.23.1-1.el8.elrepo @elrepo 
kmod-drbd90.x86_64 9.1.14-1.el8_7.elrepo @elrepo 

Best Regards, 
Nigel

Morning, 

AlmaLinux 8.7, kernel 4.18.0-425.19.2.el8_7.x86_64 

Just installed kmod-drbd9x-9.1.14-1.el9_1.elrepo.x86_64.rpm on my secondary and after a reboot was greeted with a 

drbdadm status 
r0 role:Secondary 
disk:Diskless 

Looking at /proc/drbd I noticed it still had the previous version listed 

cat /proc/drbd 
version: 9.1.13 (api:2/proto:86-121) 
GIT-hash: 834511a4957bba1a6aa4245a99ceebca5c42a4f2 build by mockbuild@, 2023-01-30 18:33:50 
Transports (api:18): 

Rebooting again into an earlier kernel, 4.18.0-425.13.1.el8_7.x86_64 and now back and working with /proc/drbd showing the correct version. 

cat /proc/drbd 
version: 9.1.14 (api:2/proto:86-121) 
GIT-hash: df55dfb7a93484b7d7eb0c4deac62d887cfcbf67 build by mockbuild@, 2023-04-08 19:54:28 
Transports (api:18): tcp (9.1.14) 

Did I miss a step on the upgrade, should I have brought drbd down first (it was set to secondary) or intitally booted into an earlier kernel first before the upgrade? 

Best Regards, 
Nigel 



You installed the kmod package built for el9 on your el8 system. Please try installing kmod-drbd90 for el8.
