Help on DS1815+ with DSM7.1.1-42962 update 6

[richarda123]

Hello,

Thanks a lot for making this script.
I was trying to expand a volume with a new HDD and I got the message about unsupported drive.
I found this script (thank you Reddit), downloaded the latest version (3.4.84) and ran it on my DS1815+.
It runs without any error but after rebooting, I still can't add the new HDD to expand the volume.

Unit: DS1815+
OS: DSM7.1.1-42962 update 6
Drive I'm trying to add: ST4000NM0033-9ZM170,EN09

Any help is welcome !

Richard

Below what I get when I run the script:

DSM successfully checked disk compatibility.

You may need to reboot the Synology to see the changes.

From your comments on reddit it sounds like the drive database is corrupted, or DSM thinks it's corrupted.
ST4000NM0033-9ZM170,EN09 and WD40EFRX-68WT0N0 both exist in the default ds1515+_host_v7.db file so they should always show as compatible.

Looking at the ds1815+_host_v7.db for DSM 7.1.1 I see it uses the old v7.db format.

What does the following command return:

ls /var/lib/disk-compatibility | grep host

Can you attach a zipped copy of your /var/lib/disk-compatibility/ds1815+_host_v7.db file to your reply. You can copy it to your home folder with:

cp /var/lib/disk-compatibility/ds1815+_host_v7.db $HOME

And to be clear, it started BEFORE I launched your script.

I did wonder about that.

Your db file is a newer version than the latest drive database update available for the DS1515+ (SynoOfflinePack-ds1815+-0020). It is as if it came from DSM 7.2.1. Did one of the drives come out of a NAS running 7.2.1?

If you have a backup of your data and a DSM settings export you could try Synology_DSM_reinstall using 7.1.1-42962 (with Update 1)

[007revad]

Try the following commands:

sudo -i cp /tmp/synodrivedb.db /tmp/synodrivedb.db.orig
sudo -i cp /var.defaults/lib/smartmontools/synodrivedb.db /tmp/synodrivedb.db

OK. Your issue was caused by Synology releasing a badly formatted smartmontools synodrive.db update. They have fixed it now so you need to go to "Storage Manager > HDD/SSD > Settings > Advanced" then scroll down to Drive Database and click on the Update Now button.

Thanks. I just tried this and I got this strange behaviour:

My station is indeed connected to the Internet. Anyway, I did the manual update process but the date of the last update remains the same: 2024-02-16 20:06:10.... and indeed this is probably when things started going down.

Also, when I do the manual process, I still get the same database version downloaded: SynoOfflinePack-ds1815+-0020. So maybe this is why it is not updating. Have you been able to get a more recent version ? (mine comes straight from the web site of Synology).
SynoOfflinePack-ds1815+-0020.sa.zip

Is that file corrupted ?
If yes, could you please send me a good one ? (this one is the onmy one I can get from the Synology support section).

Thanks a lot for all the time you spend on my issue.

The manual update (SynoOfflinePack) does not include the synodrive.db file. So you need to click on the Update Now button. The badly formatted update from the last 2 days is what causes the error message you're seeing.

Try the following commands to restore the original synodrive.db:

sudo -i
cp /var.defaults/lib/smartmontools/synodrivedb.db /tmp/synodrivedb.db
cp /var.defaults/lib/smartmontools/synodrivedb.db /var/lib/smartmontools/synodrivedb.db

It Worked !!!!!
Thanks !
This is genius !
Is this solution ok in the long run ?

[007revad]

You won't need to ever do that again... as long as Synology don't make the same mistake on the next smart drive database update.
