Gluster downgrade - partially preserved

[madmax01]

Description of problem:

every version higher then 10.1 (including 11) crashes after a while. something essential was changed

The exact command to reproduce the issue: no specific command - just crash and checked logs

Expected results: would expect no crash

- The operating system / glusterfs version: alma 8.6 + 10.1

i downgraded from 10.3 to 10.1 and restarted services

but after a while its still crashing

it tells 10.3 but when checking glusterd -V it says 10.1

can you let me know please what to change to flip completely to 10.1 - something is preserved from 10.3

@madmax01 Were you able to resolve this issue? If yes what did you do?

Hi

sry late info

no i just stayed with alma at 10.1 (i just deleted everything and cleaned every corner) as something is wrong with higher versions

on ubuntu i can tell the integrated version is stable even with 11.1 (but pitty is gnfs is not embedded).. i used gnfs and did integrated it as it was part of source.......using it with alma.

the "fuse mount" is heavy slow and nfs-ganesha is not really focusing gluster.. so means its left in the air with just fuse atm

i hope gluster community bring back an inhouse nfs logic again - able to have more performance based on latest nfs version supports

[pranithk]

So we either bring back gnfs or get support on nfs-ganesha. Re-opening it for now.

@pranithk

current 11.1 on ubuntu seems somehow stable.. but the fuse is really a perf breaker. even with nvmes.

from an user perspective i think there should be

• gnfs back in life > but in support with latest NFS. not just v3 (higher ones like 4.2 has sparse,server side clone copy,.. support and other features)
• nfs-ganesha yes as 2nd Choice if a user want dedication. 1 replicates > the other provide NFS... but this more for higher Traffic and Performance > as it can use a high lot more Buffer Space (and need to handle 2 communities which can be a problem in case of issue analyze)

thinking this would be a very good Option.. Have GNFS back with higher nfs version support as default Package... And for those need really high Performance to get nfs-ganesha stable.
