Original GitHub issue: https://github.com/007revad/Synology_HDD_db/issues/132

I shouldn't have done it... I did it 🙃

Setup:
DS1821+
E10M20-TI with 2x WD Red nvme Operating as R/W Cache for Volume 1
Volume 1: 4x SHR-2 HDD
Volume 2 - Internal nvme slots: 2x 970 Evo Plus SHR-1 Volume

Attempted to Upgrade from Update 1 > Update 3 after having issues on Update 2 and rolling back to Update 1.

Alas, similar or even worse issues on Update 3. Let me recount:

Update 3 applied. No forced reboot - everything operating normally.

Ran script 3.1.62 manually to ensure proper settings. Manually Reboot

hdd_db script scheduled to run at shutdown and boot

After reboot, no nvme volumes appear. Volume 2 missing, HDD Volume 1 Critical no nvme Cache

Drives and E10M20 show in script output but do not have any functionality from this point on. LAN 5 from the E10M20 does appear to show up.

Attempt to force downgrade to update 1 by running the reinstall script and then applying PAT file.

After reboot, this does resolve the issue with Volume 2 it appears and is functional after "update" reboot.

E10M20 still only functional for LAN thus Volume 1 remains critical.

However, even after applying the PAT, info still shows DS remains on update 3.

After rebooting once more, back to entirely broken state.

Update:

I've attempted telnet version downgrade and even the process described here using a spare drive:
https://www.reddit.com/r/synology/comments/140ywsm/how_i_broke_dsm_and_recovered_without_losing_my/

No matter what, after applying the PAT for 7.2U1 and then getting into DSM, we're on Update 3

So I guess the options are:

Figure out a way to downgrade to U1 where everything works perfectly.
or
Make E10M20 and NVME volumes work on U3.

Thoughts?

I've gotten back to Update 1!

After running the reinstall version script and rebooting, we're met with Synology Web Assistant.

I had the thought to block all outbound internet traffic from the DS as I had a hunch it might be auto-applying the Update 2 and Update 3 patches as part of the restore after manually selecting Update 1 PAT.

I was right.

However, the DS does require internet connection to begin the update with local pat. Yikes.

I enabled the firewall policy to allow traffic for a moment, started the upgrade and then blocked all outbound internet traffic.

Success, restore complete on update 1 - data volumes back. A bit of resetup to do since I deleted settings and restored throughout my debugging.

Domains contacted by web assistant that appear relevant:
update7.synology.com
dataupdate7.synology.com
dataautoupdate7.synology.com

So basically I feel like I should never update again lol

A few other people said this after update 2 was released. I've been too scared to update my DS1821+ to update 2 or 3. Though I did update my DS720+ test NAS without any issues.

Domains contacted by web assistant that appear relevant:
update7.synology.com
dataupdate7.synology.com
dataautoupdate7.synology.com

Did you capture more than just the domains?

Do you have auto update enabled for DSM updates?

Many synology.com addresses are configurable/editable in 4 different files on the DS1821+ but "dataupdate7.synology.com" is hardcoded in 2 library files. I can't tell if the libraries only use the hard coded URLs if the URL is not configured in synoinfo.conf - like the drive_db_test_url that we can add to synoinfo.conf to prevent DSM updating the drive databases with drive_db_test_url=127.0.0.1

And I can't find "dataautoupdate7.synology.com" in any of DSM 7.2 Update 1's files.

Synoinfo.conf contains:
pkgupdate_server="https://pkgupdate7.synology.com"
rss_server="http://update7.synology.com/autoupdate/genRSS.php"
rss_server_ssl="https://update7.synology.com/autoupdate/genRSS.php"
rss_server_v2="https://update7.synology.com/autoupdate/v2/getList"
security_version_server="https://update7.synology.com/securityVersion"
small_info_path="https://update7.synology.com/smallupdate"
update_server="http://update7.synology.com/"
update_server_ssl="https://update7.synology.com/"
updateurl="http://www.synology.com/"

Files containing "dataupdate7.synology.com"

https://dataupdate7.synology.com/ is hardcoded in libhwcontrol.so and libsynoinstallcpp.so

libhwcontrol.so seems to only use https://dataupdate7.synology.com/ to get Synology drive firmware updates.
libsynoinstallcpp.so seems to only use https://dataupdate7.synology.com/ to get DSM small (nano) updates via https://dataupdate7.synology.com/smallupdates.

/usr/share/data_update/data_update.conf:

{
	"config": {
		"download_scheme": "https",
		"db_netloc": "dataupdate7.synology.com",
		"db_ver": "v1",
		"cur_volume": ""
	}
}

/usr/syno.sbin/junior_expansion_pack.sh:

get_update_server_hostname() {

is there any more word on whether this will work with update 3? the work you've done is top notch, but I'm like you with your 1821+, not brave enough to attempt update past 7.2U1

Well that's good news. I would have thought more people would have posted if there were wider-ranging issues with U3 as well, so I may bite the bullet myself over the weekend. Thanks for taking the time to reply :)

Agreed. I only know of a very small number of people who had issues after updating to update 2 or update 3.

I recently bought a ds1821. I updated dsm to UPDATE 3 and installed packages. I wanted to use shr-6 ssd cache, so I bought E10M20, and ran script. but like zcpnate, all ssd cache was gone. so I restored script.. (cache drive re-appeared)

are there no option for use E10M20 on UPDATE 3?

could you do recogntion of device name change on script? ex. E10M20-T1 to E10G18-T2

Do you want the NVMe drives in the E10M20-T1 as cache drives or a volume?

Can you try https://github.com/007revad/Synology_enable_M2_card

Looks like I might need to buy a E10M20-T1 and do some testing.

I ran Synology_enable_M2_card.sh on my DS1821+ dsm7.2U3 with E10M20-T1, same phenomenon.
All M2 drives were gone. and my synology fans run louder. (like when HP server compatibility test failed)
I did restoration.

This is caused by 7.2 update 3.

Someone has kindly donated an M2 card but they haven't posted it yet. I'll do some testing on my DS1821+ with 7.2 update 3 once the card arrives.

In the meantime you can go back to 7.2 update 1 with https://github.com/007revad/Synology_DSM_reinstall but:

A DSM install needs internet access to start the installation.
But you need to kill the Internet access before DSM tries to update itself to update 3.
