Hi,
We did compare engine backups and found some differences in the LUNs
"public"."luns" (restored db from 2020.04.09)
------------------------------------------------------------------------
physical_volume_id lun_id volume_group_id
serial lun_mapping
vendor_id product_id device_size discard_max_size
wEx3tY-OELy-gOtD-CFDp-az4D-EyYO-1SAAqd repl_HanaDB_osd_01
a1q5Jr-Bd7h-wEVJ-9b0C-Ggnr-M1JI-kyXeDV SHUAWEI_XSG1_2102350RMG10HC0000210053

4TCXZ7-R1l1-xkdU-u0vx-S3n4-JWcE-qksPd1 SHUAWEI_XSG1_2102350RMG10HC0000200035
7 HUAWEI XSG1 2048 268435456
"public"."luns" (current db)
------------------------------------------------------------------------
physical_volume_id lun_id volume_group_id
serial lun_mapping
vendor_id product_id device_size discard_max_size
wEx3tY-OELy-gOtD-CFDp-az4D-EyYO-1SAAqd repl_HanaDB_osd_01
a1q5Jr-Bd7h-wEVJ-9b0C-Ggnr-M1JI-kyXeDV SHUAWEI_XSG1_2102350RMG10HC0000210053
6 HUAWEI XSG1 4096 268435456
repl_HanaLogs_osd_01
SHUAWEI_XSG1_2102350RMG10HC0000210054 7
HUAWEI XSG1 2548 268435456
We observed that the physical_volume_id and volume_group_id is missing from the
corrupt SD.
We also observed that the serial has changed on the corrupted SD/LUN.
Is the serial calculated or read somewhere?
Would it be possible to inject the missing values in the engine DB to recover
to a consistent state?
Thanks for any help.

Hi Arsène,
can you please send which version are you referring to?

can you put them in maintenance and then activate them back so it will be
synced?
I guess that it is out of sync, that's why the "Add" button appears to already
added LUNs

Hi Ahmad,
I did the following:
1. Storage -> Storage Domains
2 Click the existing Storage Domain and click "Manage Domain"
and then I see next to the LUN which is already part of the SD the "Add" button
I do not want to click add since it may destroy the existing SD or the content
of the LUNs.
In the Engine Log I see the following:
020-07-14 09:57:45,131+02 WARN

Thanks a lot

Hi Arsène Gschwind,
it's really strange that you see "Add" on a LUN that already has been added to
the database.
to verify the steps you did make at first,
1- Storage -> Storage Domains
2- New Domain - [ select iSCSI ]
3- click on "+" on the iscsi target, then you see the "Add" button is available
4- after clicking add and ok, then this error will be shown in the logs
is that right?
can you also attach vdsm log?

Hello all,
I've checked all my multipath configuration and everything seems korrekt.
Is there a way to correct this, may be in the DB?
I really need some help, thanks a lot.

HI,
I'm having a strange behavior with a SD. When trying to manage the SD I see
they "Add" button for the LUN which should already be the one use for that SD.
In the Logs I see the following:

It looks like the engine will add a LUN to an SD and it already exist...
Any Idea how to resolve that problem?
Thanks a lot
