Help: Xpenology 5.2-5644 halts during loading the device


Recommended Posts

Hi all,


Please help me solve the following issue.

I am running Xpenology 5.2- 5644.

Recently, its web address (192.xxx.xxx) is not accessible until I restart the system. Then, the SMB service does not run with this failure:

\/sbin/e2fsck returns 4, move into network install... [FAILED]


Now, the system totally halts at this step:

:Checking upgrade file [OK]


Wait 2 seconds for synology manufactory device.


It cannot be accessed through putty although SSh enabled. Neither is the Synology assistant

I tried the option no.3 at boot: 3. Install/upgrade but the problem remains

Could anyone help me:

1. Why that problem happens and how to solve the problem without losing the data on harddisk.

2 In case, I have to reinstall Xpenology, should I still use 5.2- 5644 or the older?

3. If I have to reinstall, my data on harddisk get lost or not?


Thank a lot for your attention and support.

if you have spare hard drives, you can pull out your existing drives (make sure to write down which HDD number goes to which port)

then replace with 2 HDD to re-install XPEnology

if everything works fine after installing to the 2 temp HDD

then you can clone the DSM OS partition from temp HDD to replace the DSM OS partition on the HDD you pulled out.


I did that before on legit Synology boxes to do data recovery after HDD failure corrupted the DSM OS partition requiring a re-install of the .PAT file.



Another method is to try this


it's for people that accidentally upgraded to 6.0, but it works also for people wanting to go back / downgraded to older versions.

How many disks in your array and what SHR/RAID are they?

If you have a 1 disk fault tolerant system (eg SHR1) you could try;


1) Disconnect all disks except the one on SATA port 1

2) Erase the DSM partitions with a partition utility

3) Re install DSM

4) Create and delete a volume


After these steps you should have a 'working' XPE/DSM system with a 'good' system partition


5) Shutdown and reconnect your other drives

6) DSM should boot from the disk on SATA port 1

7) Storage Manager will warn that System Partitions have failed, and Volume is crashed. You should be able to repair both
