[DRBD-user] Linstor v0.6.2

[Rene Peinthor]

Hi again!

While further testing the latest version upgrade migration, we noticed
we missed another table migration, that are fixed now in the v0.6.2 release.

linstor-server
--------------
* Fix: FreespaceMgr migration was still missing some entries in SECURITY
ACL table
* Fix: Controller trying to connect to none satellite nodes

Best regards,

Just tried 0.6.2-1 on PVE and it seems to fail with a different error this
time (Migration Failed!)....

Yes, moreover, downgrading to 0.5.0 is quite annoying, and a backup copy
of linstor db is required.

I rolled back to 0.5.0 as well, but I didn't had to restore the database.
But backing up the DB is a must anyways ...
Currently doing the test upgrades in a test (VM lab) cluster, so no harm on
the production cluster.

In my case I upgraded only one satellite node and the (pure) controller;
after downgrading, satellite remained in a something like

OFFLINE (VERSION MISMATCH)

stae, so I reverted the db as well.

Very good habit indeed. Given that I am not in a condition to do
upgrades in a testbed, i will wait for more solid upgrades, basing on
your (very precious) advices ...

Thanks,
rob

I guess I found another side effect of failed upgrade:

# linstor storage-pool list
ERROR:
Description:
(Node: 'drbdc') The requested function call cannot be executed.
Cause:
Common causes of this error are:
- The function call name specified by the caller
(client side) is incorrect
- The requested function call was not loaded into
the system (server side)
Details:
The requested function call name was 'RequestFreeSpace'.

Could one of you or both be so kind and send me your database file?
Should be in `/var/lib/linstor/linstordb.mv.db`

Cheers,
Rene

Yes, moreover, downgrading to 0.5.0 is quite annoying, and a backup
copy of linstor db is required.

The reason for that is that only few databases can run DDL statements
(statements that change the database's structure) in a transaction, so
that they can roll back a partly failed migration.

The databases where this is supported are:
- PostgreSQL
- IBM DB2

The integrated H2 database as well as MySQL, MariaDB, Oracle RDBMS,
Microsoft SQL Server and most others require either manual intervention
or a backup to fully roll back to a previous database structure after a
partially applied migration.

We will consider having LINSTOR backup the database automatically before
trying a migration, so that going back to an older version would be easier.

Robert
