Dear Stefan, what about your expectation on upgrading the OS to CentOS 8 Stream? Are there any advantages?

[Gluster-users] [EXT] upgrading OS on gluster servers
Dear Felix, Support for latest server hardware and Infiniband hardware. I'm currently running on CentOS 7, but in 2024 the latest I have to migrate to a new OS anyway. (EOL for CentOS 7). best wishes, Stefan -- Dr. Stefan Solbrig Universit?t Regensburg, Fakult?t f?r Physik, 93040 Regensburg, Germany Tel +49-941-943-2097> Am 12.05.2021 um 12:09 schrieb Felix K?lzow <felix.koelzow at gmx.de>: > > Dear Stefan, > > > > what about your expectation on upgrading the OS to CentOS 8 Stream? > > Are there any advantages? > > > > Regards, > > Felix > > On 12/05/2021 12:02, Stefan Solbrig wrote: >> Hi Strahli, >> >> Thank you for the quick answer! Sorry I have to ask again: as far as I can see, Gluster keeps all information about peers, bricks, in /var/lib/glusterd. So if I migrate to a new OS, it seems that I have to restore them. Or would you suggest rather to re-generate them by repeating all "peer probe ..." and "volume brick-add ..." commands? >> >> best wishes, >> Stefan >> >> -- >> Dr. Stefan Solbrig >> Universit?t Regensburg, Fakult?t f?r Physik, >> 93040 Regensburg, Germany >> Tel +49-941-943-2097 >> >>> Am 11.05.2021 um 13:46 schrieb Strahil Nikolov <hunter86_bg at yahoo.com <mailto:hunter86_bg at yahoo.com>>: >>> >>> Hi Stefan, >>> >>> >>> I would backup Gluster's dir in /etc . >>> You don't need to restore any configuration files after the update, but it's good to have them backed up. >>> >>> Best Regards, >>> Strahil Nikolov >>> >>> >>> On Tue, May 11, 2021 at 10:11, Stefan Solbrig >>> <stefan.solbrig at ur.de <mailto:stefan.solbrig at ur.de>> wrote: >>> Dear all, >>> >>> I was wondering what is the prefered way to upgrade the server OS (not glusterd) for a GlusterFS. >>> I'm running a distributed-only system (no replication) on centos 7, planning an upgrade to centos 8 stream. >>> >>> I suppose a possible way is like this: >>> >>> * unmount file system on all clients >>> * stop cluster >>> * copy data in /var/lib/glusterd >>> * upgrade all servers >>> * restore data in /var/lib/glusterd >>> >>> Could you please advise me if: >>> - the files in /var/lib/glusterd are all that is needed? >>> - or can I regenerate these from other data? >>> >>> best wishes, >>> Stefan >>> >>> >>> ________ >>> >>> >>> >>> Community Meeting Calendar: >>> >>> Schedule - >>> Every 2nd and 4th Tuesday at 14:30 IST / 09:00 UTC >>> Bridge: https://meet.google.com/cpu-eiue-hvk <https://meet.google.com/cpu-eiue-hvk> >>> Gluster-users mailing list >>> Gluster-users at gluster.org <mailto:Gluster-users at gluster.org> >>> https://lists.gluster.org/mailman/listinfo/gluster-users <https://lists.gluster.org/mailman/listinfo/gluster-users> >> >> >> >> ________ >> >> >> >> Community Meeting Calendar: >> >> Schedule - >> Every 2nd and 4th Tuesday at 14:30 IST / 09:00 UTC >> Bridge: https://meet.google.com/cpu-eiue-hvk <https://meet.google.com/cpu-eiue-hvk> >> Gluster-users mailing list >> Gluster-users at gluster.org <mailto:Gluster-users at gluster.org> >> https://lists.gluster.org/mailman/listinfo/gluster-users <https://lists.gluster.org/mailman/listinfo/gluster-users> > ________ > > > > Community Meeting Calendar: > > Schedule - > Every 2nd and 4th Tuesday at 14:30 IST / 09:00 UTC > Bridge: https://meet.google.com/cpu-eiue-hvk > Gluster-users mailing list > Gluster-users at gluster.org > https://lists.gluster.org/mailman/listinfo/gluster-users-------------- next part -------------- An HTML attachment was scrubbed...
