Upgrade to 6.0.0 - Database upgrade fails

Filipp Sudanov

yes, that's background migration, server reads collected data both from non-migrated and migrated tables, so everything should work even during migration.
Would be interesting to know how long it takes on your system and how big it is (sh st output - number of nodes, dci count, size of the DB)

Finished in about 15 minutes, db is around 8GB, not sure how many nodes

2026.02.10 11:35:45.590 *I* [dc.v5migrate ] Migrating recent data from v5 tables (106 idata, 3 tdata)

I can see that the database upgrade is happening in the background, but the netxms-server service won't start.

"Your database has format version 60.7, but server is compiled for version 60.32"

Are you still in upgrade to 6.0.0, or you've restarted upgrade to 6.0.1?

...happening in the background - is it nxdbmgr background-upgrade running? If so, you need for it to finish and then run nxdbmgr upgrade again - it will upgrade schema further. This step could be a background one in 5.2, but when upgrading to 6.0 we need it to complete prior to subsequent db upgrade steps.

I saw the database upgrade start when I used apt get upgrade. I thought that the server could then be started while that was running, but I suppose not.

Hi,

Did all the updates/upgrades to be on 6.01, rebooted, bus till

NetXMS Database Manager Version 6.0.1 Build 6.0-469-g5e68d5db1d

Upgrading database...
Upgrading from version 60.7 to 60.8
SQL query failed (25P02 ERROR: current transaction is aborted, commands ignored until end of transaction block):
CREATE TABLE tdata_16066 (item_id integer not null,tdata_timestamp bigint not null,tdata_value text null, PRIMARY KEY(item_id,tdata_timestamp))
Rolling back last stage due to upgrade errors...
Database upgrade failed

On Debian 13
PostgreSQL 17.7

Any fixes or workarrounds ?

Thanks

twparker

I am receiving similar errors, but I believe I caused my own problems by running the commands that Victor posted earlier.

DROP TABLE idata;
CREATE TABLE idata
(
item_id integer not null,
idata_timestamp integer not null,
idata_value varchar(255) null,
raw_value varchar(255) null
);
DROP TABLE tdata;
CREATE TABLE tdata
(
item_id integer not null,
tdata_timestamp integer not null,
tdata_value varchar(max) null
);

Is my database irrevocably damaged?

Filipp Sudanov

dlauwers, twparker
can you run
nxdbmgr -t upgrade

This is to see what exactly it's doing there

Getting a lot of text - here's a snippet

DROP TABLE tdata_8505

This appears more relevant

>>> RELEASE SAVEPOINT nxdbmgr_1771000399839
>>> SELECT var_value FROM metadata WHERE var_name='IDataTableCreationCommand'

Database upgrade failed
>>> SELECT var_value FROM metadata WHERE var_name='PendingOnlineUpgrades'

Filipp Sudanov

There was some query just before CREATE TABLE idata_46970 which failed.
60.7 to 60.8 handles idata/tdata tables, doing this:

1. Check if idata_<id> exists
2. If the table is empty → DROP it
3. If the table is not empty → RENAME it to idata_v5_<id>
4. Create a new idata_<id> table using CreateIDataTable(id)

Pls check, do you have
idata_46970
idata_v5_46970
tables in the DB?

If idata_46970 is there, pls show output of
\d idata_46970

Hi, this is the result

It is "working on" Create Table tdata_16066 for about 5 minutes and then it fails

Check Postgres’s log - good chance you run out of shared memory

dlauwers

Seems that the table is empty ?

postgres psql -d netxms -c "SELECT * FROM idata_16066 LIMIT 10;"
[sudo] password for xxxxxx:
item_id | idata_timestamp | idata_value | raw_value
---------+-----------------+-------------+-----------
(0 rows)

YES !!

I have increased the shared memory, and now no error

sudo nxdbmgr upgrade

NetXMS Database Manager Version 6.0.2 Build 6.0-504-g549db2d3a0

Upgrading database...

Core database schema is up to date

Database upgrade succeeded

twparker

I had to increase my shared memory and increase max transaction locks, but I am also back in business.

In general I always recommend to start with https://pgtune.leopard.in.ua, when using Postgres
