[5.2-5565 stopped booting after power supply replacement]

Well that was really educational. The key was the USB drive blinking like crazy. It took me a while to realize it but the drive only showed up twice in ubuntu, I created a new xpenoboot and the system booted up fine. I logged in and it reported an unhealthy boot partition which repaired with no issues.

 

I noticed under ubuntu that the boot raid partition didn't assemble from

 

sudo mdadm --assemble --scan

 

is that normal?

I took fjf's advice and booted off of a ubuntu USB. I was able to mount my filesystems no problem following this process

 

https://forum.synology.com/enu/viewtopi ... 60&t=51393

 

So my filesystem is good , I shutdown the system removed the ubuntu usb and reinserted the xpenoboot usb, boot up the system and it hangs in the same spot, one thing i noticed is my xpenoboot usb drive has a led on it for activity and it just keeps blinking furiously while my HDD drive lights are idle.

 

I can build a drive with 5.2 on it, but is it the hdd drive partition or the boot usb that needs to be repaired?

I can see all of my drives in the bios, synology assistant doesn't see this system but does see my synology box. None of my drives are blinking so I don't think it is checking the volumes.

 

I will try booting a live ubuntu system next.

ok so in debug mode this ever repeating line is ok?

 

USB 7-3: new high-speed USB device number xx using ehci-pci

 

I will check the drives when I get home and try to look at the system with synology assistant.

[5.2-5565 stopped booting after power supply replacement]

My power supply died and when i replaced it my xpenology running 5.2-5565 doesn't boot fully any longer

booting gets as far as

 

:: Starting /usr/syno/bin/synocfgen...

/usr/syno/bin/synocfgen returns 0

Partition Version=0

Partition layout is not DiskStation style.

NOT EXECUTE /sbin/e2fschk.

Mounting /dev/md0 /tmpRoot

:: Checking upgrade file

Wait 2 seconds for synology manufactory device

 

If i boot in debug mode it continuously outputs

updating debug.log

USB 7-3: new high-speed USB device number xx using ehci-pci

 

where xx is a whole series of numbers that repeats eventually.

 

Did I maybe get my usb cables mixed up? Any help appreciated!
