DSM 7 - NAS is freezing

[Mira]

Hello,

we own Synology NAS DS216j. After updating DSM from version 6 to version 7 the NAS completely freezes. The reset button does not work either. Sometimes after connecting to electricity it starts up and runs for a few days before it freezes completely again, sometimes freezing during starting. All lights are on, the LAN light is blinking. NAS does not respond to ping requests, we can't connect using SSH, https or any other way. Writing to log files is interrupted in the middle of the line.

Here is example of log report (systemd.log) at freezing time:

Thank you for your help.

Sorry to hear that. Your unit has half the minimum recommended memory for DSM7. The performance you see is not unexpected. You may see slight improvement once the initial indexing is complete.

Alternatively, you may roll back to DM7 using unsupported procedures.

Thank you for your explanation. I do not understand why the Synology offered an upgrade to unsupported version of the OS without any warning. We can wait to see if the problems disappear or we will downgrade.

DSM7 is supported. It just won't perform well in your setting. The memory requirement is stated in the DSM7 release notes.

That said, I don't know why Synology made the upgrade available to units which have no ability to upgrade memory. Even some of their newest offerings, fall short of the DSM7 memory requirement.

I am having the same issue after upgrading from DSM 6 to 7, but I have DS918+. The only difference is that it freezes about 1 minute after a reboot. I noticed that it freezes when it starts one of the apps that I installed. Funny thing is that all the apps I run on this DSM are from Synology... I opened two tickets to get some help from Synology Customer Support, but they didn't help. I noticed that I can force shout down the DSM by holding the power button for few seconds, then remove some of my disks and when I start it with disks being pulled out - it starts and doesn't freeze. I think that the reason is that the apps aren't running. But it freezes as soon as I begin starting them. I have one last idea - I'll do a factory reset to erase all data from it and all apps, and after this I'll perform a reset mode 2.

Thank you for sharing your experience. Our NAS has already stabilized and has been running without freezing for almost a month. If it freezes further, I would try the unofficial downgrade option or throw it in the trash.

Do you have ram upgraded inside that NAS? If so what brand and how much total ram are you running?

My DS718+ with 16GB of RAM is doing the same and has been for a fortnight now, never had this issue on DSM 6. Sick of it. Researching a move to QNAP.

Researching a move to QNAP

Probably the ram problem. Be careful with QNAP. Several topics even here on the forum about recent ransomware problems and forced OS updates. Just be aware of where you are going.

Thanks for the reply, what's the "RAM problem"?

Memory section. DSM7 has certain hardening elements. It could be that it's pickier about the amount of ram considering you are going over the recommended and supported limit.
