I am trying to install the OMV OS onto a USB device. I am using the iLO and that allows me to select a image file and use it as a boot device. So I boot using the OMV and I am able to install OMV and it gets all the way to the end of the installer and then complains about GRUB and asks me to chose which device to install GRUB, I select the device and it appears to work fine but then after reboot I get to the grub rescuse screen and can't boot.

Yes I installed to one of the 8 hard drives and that is fine. I event tried using clonezilla and cloning a working copy and then put it on a SSD connected via USB and that failed to boot as well.

Any assistance is appreciated. Thanks in advance.

I've had that problem sometime ago, and as far as I can remember it pointed to a problem with grub, that was installing to a wrong drive.
May be you are install from an USB (iso with OMV) to another USB ?
If so , I would recommend to use another media for the OMV-ISO (CD/DVD) and test.

I'm trying to install OMV4 on my DL-360 G7 using the internal USB or SD Card reader and after the installer finishes it never installs Grub properly. I tried the internal USB slot as well as the external USB using both USE cards as well as a SATA drive connected via a USE connector.

Has anyone ever had a problem installing via USB on a G7 ?

Can you elaborate what/where is your problem ?
Are you trying to install from USB to hard disk or form xx to USB ?

If first option:
-I've done it on a DL360-G5 but it needs to add ahcpi=off to grub options... and have some problems after (do not shutdown properly)
-Also on a DL-380-G7 without problem.

If second option:
-Have you tried to install to hard disk ?

Tested.
Some warnings during install, but works as expected.

Thanks

Thanks, will try it later, and post results...

The plugin hasn't had a commit in over a year.

Any possibility to have shellinabox available for arrakis ?

You should add a parameter 0, or 1 as explained above.
I.E :

# ./zpool_checker.sh 0
or
# ./zpool_checker.sh 1

Please post your script

You must pass an parameter , 0 or 1 , to not [0] or yes [1] force the sent of an email, to your script.

@du_ku
Did you see Post #712 ?

To test for ZFS health, and send an email if fails, I run a small script every 5 minutes that looks for the result of zpool status.

I adapted from this one :
>>> gist.github.com/petervanderdoes/bd6660302404ed5b094d

#!/bin/sh
enviar=0
equipo=$( hostname | cut -d . -f 1 )
destino="xxxx@xxxx.net"
asunto=" Estado del ZFS de ${equipo}"
comandozpool1="/sbin/zpool list -H -o health "
comandozpool2="/sbin/zpool status -x"
# I need parameter $1 to know If I want to force send an email
forzar=$1
# Comprobar Salud
pstatus=$( $comandozpool1 )
if [ "${pstatus}" != "ONLINE" ]; then
msg="Problemas con ZFS: \n \n $($comandozpool2 )"
enviar=1
fi
if [ "${forzar}" -eq 1 ]; then
msg="Envio Forzado estado ZFS: \n \n $($comandozpool2 )"
enviar=1
fi
# Enviar correo ?
if [ "${enviar}" -eq 1 ]; then
echo " ${msg} " | mail -s "${asunto}" ${destino}
fi
exit 0

I run it via cron every 5 minutes with parameter 0
and once every friday with parameter 1 to force it to send an email

Hope you can understand it, if not, let me know

Did you delete the cache files also?

/var/cache/openmediavault/cache*.json

Yes, also performed several reboots after that...

P.S. Remeber, I'm trying 4.09>updated to 4.11

Is the THEME=gray option still avaailable in 4.09 ??

I've tried
echo 'OMV_WEBUI_THEME=gray' >> /etc/default/openmediavault
with no success ....

Yes proxmox can run from zfs. You can choose filesystem during install.

Scenario:
New installation from openmediavault_3.0.58-amd64.iso To an USB flash Disk (8GB).
Web update via WEb to 3.0.67 with no problem. reboot.
Installed omv-extras 3.3.7
Installed Flash-Memory 3.4.3 . Modify /etc/fstab as instructed. Enable pluging, and reboot.
On reboot , systems hungs after Loading initial ramdisk .... message.

Looking as grub advanced options I see that I am running kernel 4.9.0-0.bpo.2-amd64

and also have 4.8.0-0.bpo.2-amd64 (seems that update to omv 3.0.67 has installed 4.9.0 kernel)

Selecting (grub) 4.8.0 kernel, system starts with no problem, and FlashMemory pluging works !! (result of mount has lots of entries with folder2ram)

It seems to me that there is some kind of problem betwen 4.9.0 and ramdisk...

Any hints ?

Thanks for the css example.

This way, text can be read.

Quote from ryecoaaron

The textarea is read only now. The color changed in OMV 3.x. You probably could change the css color by creating /var/www/openmediavault/css/omv-custom.css

Any example of this would be appreciated. (No knowledge about css).
Thanks

First of all, I must say that I no expecience with Snapraid + MergeFS. So I can miss something important.

Agree with you:
For data disks, use ZFS under proxmox (and also raidXX what ever you choose)
Pass a ZFS volume to the VM (no need to raid inside the VM)

You can also use your 2 x SSDs to hold (besides Proxmox system) system disks for some of the VMs. (I have proxmox running on 32 GB SSD). So your 'special' VMS can beneficiate from the speed of them.

Quote from ryecoaaron

LVM can also be dangerous if the disks underneath it don't have redundancy and the LVs/VGs are spread across multiple disks.

Correct !!
So I will definitively go to ZFS. (Hope to have some time....)

-LVM is very simple to use. It's main advantge is the abilty to expand storages. I repeat is very easy to use!

Proxmox is a Virtualization GUI that makes you create/manage virtual machines. Of course have (can have) all the linux utilities that you can need. Proxmox handles LVM from it´s GUI. (lot of tutorials)
-ZFS is not so simple, but seems to have much more power (currently testing)

Proxmox supports from the box ZFS (I've not yet had the time to test).

If you like to 'play' definitively go to Proxmox:
You can create a virtual machine, install OMV, add 4 disks to create a RAIDZ2 pool , detroy 1 or 2 disks and probe that data is still there. Add two new drives and check how they are resilvered. And finally add 4 more disks join them them to the pool to obtain doble storage.

Once decided the configuration make your OMV serve your data, and when another OMV release is out, create a new VM and test it. If you like the new release, you can 'move' your disk to your new VM, and you are running the 'new' OMV release with your 'old' data.

(Note ZFS for OMV 3.0x is currently in Beta stage).

Another (my) approach using Proxmox & OMV is:

- Proxmox is installed on a 32GB SSD.
- All the external storage (xxxTB)is installed and given to proxmox, defined via LVM.
- OMV (VM) has 2 disks: 8 GB for System and xxTB for DATA. Storage is defined in Proxmox GUI (LVM)
- Every VM uses same approach. OMV is only used as a NAS for physical machines, Video, ....

Advantages:
All storage is handled/controlled/checked by proxmox. No need to passtrough. Very easy to maintain.
If any machine needs more storage, size (of the second disk) can be incremented (via LVM)
If all storage defined to proxmox is used, increase storage to Proxmox (under same VG) and again you can resize LVM for a given VM
For VMs access to storage is quicker trough Proxmox ( For rest of physical machines is a bit slower ).
Much more flexible for creating/destroying VMs, I.E. testing new releases of OMV (actually testing ZFS 3.03)
