Boot Fails ... Flash-Plugin? USB-Mount?

mipi · 20. Juni 2015

After Installing the Flash-Media-Plugin the system crashed when Mounting the Backup-Medium (ext. USB-HD) ... My System: Asrock Q2900, 2x HD (Array Data Raid1), 1x SSD (System)

The Frontend won't come up and dies:

Code

Error #6000:
exception 'OMVException' with message 'Failed to open file (filename=/var/cache/openmediavault/cache.omvwebguilogin_js.json, mode=w+).' in /usr/share/php/openmediavault/util.inc:168
Stack trace:

#1 /var/www/openmediavault/index.php(41): OMVHtmlPageAbstract->render()
#2 {main}

What have I done wrong, what can i test?

Sorry, wrong location...

rm /var/cache/openmediavault/cache.omvwebguilogin_js.json

mipi · 20. Juni 2015

Their ist no dir openmediavault in /var/cache

tekkb · 20. Juni 2015

Did you reboot after enabling the plugin???

You should have this openmediavault folder in /var/cache

cd /var/cache
mkdir openmediavault
chmod 755 openmediavault
chown openmediavault:openmediavault openmediavault

Then try to login.

tekkb · 20. Juni 2015

Show your fs2ram.conf too:

cat /etc/fs2ram/fs2ram.conf

Du kannst auf Deutsch schreiben.

tekkb · 20. Juni 2015

In the fs2ram.conf there is a line for /var/cache

Code

tmpfs    /var/cache    keep_file_content

If it says keep_file_structure it needs to be changed.

I don't remember, if I rebooted after installing. But after installing the openmediavault-dir I can enter omv again. Many thanks! But is It all done now?

You quoted for the fsram.conf, cat /etc/fs2ram/fs2ram.conf shows

I recommend the line

# swap was on /dev/sdc5 during installation
# UUID=c409be98-4aab-40b9-96c7-9308a11935b4 none swap sw 0 0

I uncommented the line above during the installation ...

the line is "tmpfs /var/cache keep_file_content - tmpfs" ... right? But what happens with it next? Mal die Suchfunktion bemühen.

PS: Is their a way to check trimming and installation of the ssd in general?
PPS: Is using a SSD appropriate?

The swap partition is not used with the flashmemory plugin. If you uncommented a swap line in fstab you should have not done this. A swap file is used with the flashmemory pluigin instead of using a swap partition.

mipi · 21. Juni 2015

SChon wach? Willkommen in meiner Welt ...

I can't remember, on which step in the Installation I was reccomended to do so. Should I leave it uncommented or redo it in the fstab?

What is on my question how to test it? Do you have a answer? Am I shure with my installation? This question is virulent, because I have the old NAS-Hardware, which I wanted to transfer from a formerly used readybuilt-Zyxel-NAS.

I am in bed on my tablet, can't get back to sleep.

It should look like this, with the comment (#) at the beginning:
# UUID=c409be98-4aab-40b9-96c7-9308a11935b4 none swap sw 0 0

I think your system is fine but the openmediavault folder is missing it can't write to that folder. Did you recreate and what happens then?

mipi · 21. Juni 2015

Ja ... added the dir after your Instructions than it worked .. thanks once more, but: where had it gone?

The line with the quotation-Mark?

# swap was on /dev/sdc5 during installation
# UUID=c409be98-4aab-40b9-96c7-9308a11935b4 none swap sw 0 0

This is how it looks like after installation ... kann so bleiben!

tekkb · 21. Juni 2015

Ich geh. Tut mir leid aber Ich brauche mehr Schlaf.....

mipi · 21. Juni 2015

Heia gut

mipi · 21. Juni 2015

Mist, eben installiere ich ein neues Modul (Plex) mit neuetart ... selbes Spiel:

Code

Error #6000:
exception 'OMVException' with message 'Failed to open file (filename=/var/cache/openmediavault/cache.omvwebguilogin_js.json, mode=w+).' in /usr/share/php/openmediavault/util.inc:168

#2 {main}

Das ist jetzt aber was, was in eure Zuständigkeit fällt, oder?

tekkb · 21. Juni 2015

Recreate the openemdiavault folder if missing again with instructions above....

Your system drive is SSD yes???
If so edit the system drive in /etc/fstab and use these options:

Code

ext4 noatime,discard,errors=remount-ro 0       1

Then try rebooting...

mipi · 21. Juni 2015

Gonna try this ... you can see my fstab quoted before in the thread ...

fstab looks now like this:

Code

# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

PS: Booting and Fileservices are up, it is the frontend what is failing

PSS: Creating the dir makes the frontend working ... trying too reboot ...

tekkb · 21. Juni 2015

Yes, it is not set for trim. I do not know if this is the problem but trim should be set. It is like the stuff in tmpfs is not being saved at shutdown.

mipi · 21. Juni 2015

I rebooted to halt and brought up again, its working ... please understand me to be a little nervous, when the system won't come up ... even the fileserver is up ...

many thank, but understand when i'm sitting here with with perked ears at my new baby ...

tekkb · 21. Juni 2015

This fs2ram stuff is fairly new here. It is not perfect but it is running very well on many systems now. I think if your system drive options had been correct you would not have had this problem.

Any time you hold back writes in ram there is more risk involved. That is the nature of the beast.

With a good SSD you do not have to use fs2ram. If you are using any type of flash like a usb drive/sd card you really need to use the flash memory plugin because if you don't it will kill these type of devices in perhaps weeks.

Jetzt mitmachen!
