Running 6.2.3 on ESXi? Synoboot is BROKEN, fix available

Recommended Posts

For those Linux newbs who need exact instructions on installing the script, follow this here.  Please be VERY careful with syntax especially when working as root.

  1. If you have not turned on ssh in Control Panel remote access, do it
     

  2. Download putty or other ssh terminal emulator for ssh access
     

  3. Connect to your nas with putty and use your admin credentials.  It will give you a command line "$" which means non-privileged
     

  4. In File Station, upload FixSynoboot.sh to a shared folder.  If the folder name is "folder" and it's on Volume 1, the path in command line is /volume1/folder
     

  5. From command line, enter "ls /volume1/folder/FixSynoboot.sh" and the filename will be returned if uploaded correctly.  Case always matters in Linux.

    $ ls /volume1/folder/FixSynoboot.sh
    FixSynoboot.sh

     

  6. Enter "sudo -i" which will elevate your admin to root.  Use the admin password again. Now everything you do is destructive, so be careful.  The prompt will change to "#" to tell you that you have done this.

    $ sudo -i
    Password:
    #

     

  7. Copy the file from your upload location to the target location.

    # cp /volume1/folder/FixSynoboot.sh /usr/local/etc/rc.d

     

  8. Make the script executable.

    # chmod 0755 /usr/local/etc/rc.d/FixSynoboot.sh

     

  9. Now verify the install. The important part is the first -rwx which indicates FixSynoboot.sh can be executed.

    # ls -la /usr/local/etc/rc.d/FixSynoboot.sh
    -rwxr-xr-x  1 root root 2184 May 18 17:54 FixSynoboot.sh

     

Ensure the file configuration is correct, reboot the nas and FixSynoboot will be enabled.

Thank you very much @flyride for his extremely well written article!! 💪👏

 

I will try your solution today on my second backup NAS, which runs as a VM under ESXi 7.0 (since yesterday 😀 ) on a HPE Microserver Gen8 (as DS3615 with 1.03b) and give some feedback.

 

So to make it clear. I will:
 

- install the Update 6.2.3 manually

- reboot DSM as part of the update process (as usal)

- afterwards I will see the loader as ESATA

- I will apply/install your script

- reboot again

=> and now the loader disappears as ESATA and everything is like before

It seems that I am unable to edit my first post so I have to make another one instead:

 

 

After applying the `FixSynoboot.sh` the first time the Loader disappears as ESATA-Devices but also at the same time I lost the access to the serial console (which is my last resort of contact if something will failing).

I found my failure was I just made a `chmod 755 FixSynoboot.sh`.
I deleted the `/usr/local/etc/rc.d/FixSynoboot.sh` and rebooted: I got access to the serial console is back again. :-)

At the reboot after deleting `FixSynoboot.sh` I see some messages again regarding the console:

[341.514080] synobios write k to /dev/ttyS1 failed
[341.558121] synobios write k to /dev/ttyS1 failed
[341.591942] synobios write t to /dev/ttyS1 failed

 

The solution is to apply the rights correct as:

root@ds2:~# chmod 0755 FixSynoboot.sh
root@ds2:~# cp FixSynoboot.sh /usr/local/etc/rc.d/

(Just as you have written! :-) ).

 

After a second reboot I get now a message "External device External SATA Disk1 on ds2 was not ejected properly." and I see two new shares "satashare1-1" and "satashare1-2" with the content of the Loader:
 

# Rights and Owner of the script:

I do not know where my error is or if its an issue with the loader 1.3b (you have written that you take the parts of the script from loader 1.4b).

 

My Loader was not edited in any way besides just the PID/VID and MAC-Entries as usal.

Then I started the script manually as root and the ESATA-Shares went away:

# manually start the script:
root@ds2:~# ./FixSynoboot.sh start

# check ESATA-mounts afterwards:
root@ds2:~# mount | grep satashare

# check contents of ESATA-Shares:
root@ds2:~# ls -lah /volumeSATA1/satashare1-2
total 8.0K
drwxrwxrwx 2 root root 4.0K Apr 18 11:13 .
drwxr-xr-x 6 root root 4.0K Apr 18 11:13 ..

root@ds2:~# ls -lah /volumeSATA1/satashare1-1
total 8.0K
drwxrwxrwx 2 root root 4.0K Apr 18 11:13 .
drwxr-xr-x 6 root root 4.0K Apr 18 11:13 ..

 

In DSM I see "External device External SATA Disk1 on ds2 was not ejected properly."

 

I think that the the script is time or order related to run or there is a DSM-unmount command missing.

 

I found a shell unmount command for USB-Devices (e.g. `/usr/syno/bin/synousbdisk -umount sdk1`) but I haven't found a similar command for correctly unmounting ESATA-shares in DSM from the shell. :-(

 

I just tried:

root@ds2:~# umount /dev/sdm1
root@ds2:~# umount /dev/sdm2

 

I works but `satashare1-1` and `satashare1-2` are remaining empty in DSM.

 

After another reboot there is only one mount left:

root@ds2:~# mount | grep sdm
/dev/sdm1 on /volumeSATA1/satashare1-1 type vfat (rw,relatime,uid=1024,gid=100,fmask=0000,dmask=0000,allow_utime=0022,codepage=fault,iocharset=default,shortname=mixed,quiet,utf8,flush,errors=remount-ro)

 

 

 

So I think there is a time or order related issue left with the script or we need to cleanup the auto mounted "ESATA"-shares afterwards.

 

 

EDIT:

 

So I am now pretty sure that there is really some time or order related issue.

 

- I inserted the function "FixSynoboot" into "/etc/rc.local" so it runs a little bit earlier in the boot process. :-D

 

- Now I don't have any mounts in DSM regarding ESATA and it looks clean. :-)

 

- But I lost the serial console again. Not the entire console (I must correct myself) but there is no login-prompt anymore. Messages are still written to the console but I am unable to login.

 

- I can access the console via ssh without problems. So there must be a link between the loader and the local serial console.

 

- I will comment out my edits in "/etc/rc.local" and will use the standalone script in "/usr/local/etc/rc.d/FixSynoboot.sh" again. Better to have some entries left in DSM than no login prompt anymore via the serial console.

 

Maybe you have an idea how to solve the remaining issues. :-)

So, a couple of comments.

 

There isn't anything in Jun's script that has anything to do with the console.  It only manipulates devices that have a partition structure.  If the console is failing it has to be a general problem with 6.2.3 and the loader, or something else is going on.  Can you reboot a few times and see if that behavior is reliable? 

 

That code from 1.04b is identical to 1.03b and is probably the same back to the first Jun loader.

 

There are really two problems being solved here - First, the synoboot device is being generated as a generic block device in the range reserved for esata. If a device exists too late in the boot sequence, DSM sees the device and tries to mount the share.  So we want the device gone before that.  Second, we need the boot device to be present as synoboot.

 

When you are checking on status, ls /dev/syno* and you should see synobios and three synoboot entries if everything is working right.

 

I was hoping not to have to recommend this, but if you either change DiskIdxMap=1600 in grub.cfg, or change the portcfg bitmasks in /etc/synoinfo.conf, that will keep the esata shares from generating, and you can keep running the synoboot fix in /usr/local/etc/rc.d

 

Then all we have left is the console problem, which I really think is unrelated here but warrants investigation.  AFAIK /dev/ttyS1 is the general-purpose I/O port in Syno hardware to manage the lights and beep and fanspeed and doesn't do anything in XPenology.  I think the console is /dev/ttyS0.  It might be informative if you did a dmesg | fgrep tty

Thank you for your suggestions!

 

I will compare everything from the ground up and give feedback. Just to make sure that I do not have any settings which are not default in the grub.cfg. :-)

 

These are my current entries in the grub.cfg:

set common_args_3615='syno_hdd_powerup_seq=0 HddHotplug=0 syno_hw_version=DS3615xs vender_format_version=2 console=ttyS0,115200n8 withefi elevator=elevator quiet syno_port_thaw=1'

set sata_args='sata_uid=1 sata_pcislot=5 synoboot_satadom=1 DiskIdxMap=0C SataPortMap=114 SasIdxMap=0'

It was a long time ago that I must have a look into the grub.cfg and I am not sure if this is modified or not.

 

I have 2 SATA Disks connected to the the VM:

- "SATA Controller 0" with a 32 GByte VMDK connected as "SATA 0:0" (for some packages). This will be seen as /volume1 in DSM.

- "SATA Controller 1" with the 50 Mbyte-Loader connected as "SATA 1:0"

- and finally 1 Dell H200 flashed to IT-Mode with pass through to the VM (these are the data-disks) which will be seen as /volume2 in DSM.

 

Maybe this is the root of the issue. But the VM runs fine for about 2 years now. :-D

 

I just tried to swap SATA 0:0 with 1:0 and change the boot order in the BIOS of the VM:

- DSM is booting but /volume1 is not found anymore.

So I changed the settings back to the original ones.

 

Besides these Tests I rebooted a few times and till now I have a stable serial console on  /dev/ttyS0 just like described in grub.cfg:  "console=ttyS0,115200n8".

 

EDIT:

 

The syno-devices are looking good with the script in "/usr/local/etc/rc.d/FixSynoboot.sh" and the above settings for the VM:

root@ds2:~# ls /dev/syno*
/dev/synobios  /dev/synoboot  /dev/synoboot1  /dev/synoboot2

I was able to duplicate your report with the esata shares populating before the loader device is killed.  Apparently some differences on boot timing with 918 and 3615 I guess.

 

The DiskIdxMap=1600 should solve the esata problem on 3615 for now, but I'm searching for a simpler fix to the script.

Thank you very much for the new updated version of your script!
It work absolute fabulous! :-)

I just exchanged the first version with the new one and rebooted a few times:

 

root@ds2:~# chmod 0755 FixSynoboot.sh
root@ds2:~# cp FixSynoboot.sh /usr/local/etc/rc.d/
root@ds2:~# reboot

 

- the script works very well! :-)
- the login of the serial console stays now rock stable and did not disappears once since the new script is used
- in DSM are no remaining remnants left from the loader :-)

 

- in the console of course I can see the loader still as block device:

 

root@ds2:~# lsblk
NAME                            MAJ:MIN RM  SIZE RO TYPE  MOUNTPOINT
[ .... other block devices .... ]
sdm                               8:192  0   50M  0 disk
├─sdm1                            8:193  0   15M  0 part
├─sdm2                            8:194  0   30M  0 part
└─sdm3                            8:195  0    4M  0 part

 

or a little bit longer:
 

root@ds2:~# lsblk --fs
NAME                            FSTYPE            LABEL                      UUID                                   MOUNTPOINT
[ .... other block devices .... ]
sdm
├─sdm1                          vfat                                         00C2-16A7
├─sdm2                          vfat                                         2016-2016
└─sdm3

 

I installed "lsblk" as ipkg as it is my favorite command to list block devices in a much more human readable way. :-)

 

The loader is correctly available:
 

root@ds2:~# ls /dev/syno*
/dev/synobios  /dev/synoboot  /dev/synoboot1  /dev/synoboot2


So for now I can only say "Thank you very much!" and I have a lot to do to understand the new parts of the script. :-D
I never had contact with "uevents" before and it looks that my unmount-commands are not so bad at all.
"synocheckshare" is the next command which I will have a deeper look also. :-)

 

I will run this for a few days and then I am going to update my main NAS.

Have a nice day!

The existing loader works, and the individual that authored them has not been active since January (and historically is not active period).  So I would not expect any updated loader.

 

You have to make your own decision about when to pull the trigger on upgrades as they do take some time to sort out.  That said, 6.2.3 seems like a good release for XPEnology as many of the interim hacks that were necessary for 6.2.1 and 6.2.2 are not needed anymore (in fact, most of the problems people are having with 6.2.3 are because they still have those hacks in place and they no longer work properly).

 

The issue was partially a problem before and folks lived with it. This is a complete fix despite the band-aid style implementation.

I just installed 6.2.3 on EXSi 7.0.0 with the script and it worked fine! 
 

Now i moved my 5 disks from the N54L to EXSi in the right order, RDM Mapped to the VM and after reboot i have my old server runnig. Even not a migration was necessary!

I noticed that the eSATA volume removal method left a reference in a volume table which caused constant errors to be posted to /var/log/messages.  Also under certain circumstances the folder structure is left intact from the eSATA volume mount (this may actually be normal behavior with eSATA/USB shares).

 

Neither of these are issues that affect functionality or are visible in normal operations, but I updated the script to clean them both up.

So, what the steps for installing this update?

Should i install this script before or after installing the update?

 

In previous post #4, it seems that i should install this script after install the update in DSM, but wont there be a problem because the vm will boot once with no script installed?

It won't hurt to install it on your current system.  But it can be installed after, it isn't a problem to boot without it, you will just have "ESATA" shares exposing your loader until you install it.

 

If you think about a clean install (or a major version upgrade involving a loader change) there is no way to install the script ahead of time, so it must work without it.

thank you!!!

 

Can confirm that. 6.2-4 ist my proxmox version. 2 Test Versions updated from 6.2.3-25423 to DSM 6.2.3-25426 with juns loader 1.04
