Hi All,
Just successfully(?) completed a "live" update of the first node of a
Ceph Quincy cluster from RL8 to RL9. Everything "seems" to be working -
EXCEPT the iSCSI Gateway on that box.
During the update the ceph-iscsi package was removed (ie
`ceph-iscsi-3.6-2.g97f5b02.el8.noarch.rpm` - this is the latest package
available from the Ceph Repos). So, obviously, I reinstalled the package.
However, `dnf` is throwing errors (unsurprisingly, as that package is an
el8 package and this box is now running el9): that package requires
python 3.6 and el9 runs with python 3.8 (I believe).
So my question(s) is: Can I simply "downgrade" python to 3.6, or is
there an el9-compatible version of `ceph-iscsi` somewhere, and/or is
there some process I need to follow to get the iSCSI Gateway back up and
running?
Some further info: The next step in my
"happy-happy-fun-time-holiday-ICT-maintenance" was to upgrade the
current Ceph Cluster to use `cephadm` and to go from Ceph-Quincy to
Ceph-Reef - is this my ultimate upgrade path to get the iSCSI G/W back?
BTW the Ceph Cluster is used *only* to provide iSCSI LUNS to an oVirt
(KVM) Cluster front-end. Because it is the holidays I can take the
entire network down (ie shutdown all the VMs) to facilitate this update
process, which also means that I can use some other way (ie a non-iSCSI
way - I think) to connect the Ceph SAN Cluster to the oVirt VM-Hosting
Cluster - if *this* is the solution (ie no iSCSI) does someone have any
experience in running oVirt off of Ceph in a non-iSCSI way - and could
you be so kind as to provide some pointers/documentation/help?
And before anyone says it, let me: "I broke, now I own it" :-)
Thanks in advance, and everyone have a Merry Christmas, Heavenly
Hanukkah, Quality Kwanzaa, Really-good (upcoming) Ramadan, and/or a
Happy Holidays.
Cheers
Dulux-Oz
