RAID and LVM and mounting issues

First a bit of background. I'm trying really hard to get omv working on a netgear readynas ultra 6. I've come so close, but yet, every sollution somehow at some point seems to wanna backfire.

1. Install omv on a thumbdrive: this went great, until the uptime was longer than 24 hours at wich point the system just crashed. Since you have to manually intervean to reboot propperly, this is not really a workable sollution. Other than that, I did get jellyfin up and running after recreating the log directory and adding a firewall rule for port 8096 (i think)

2. Use a debian 11 netinstall with raid and lvm. Great, since I don't have to offer up a disk, I thought, more diskspace to store backups, I thought... But the moment I add "/dev/dm-2

XFS

Online"

the web UI spits out a fancy error... It seems I'm not the only person having this, and as of yet, it also seems there's no sollution for it...

the error:

"

500 - Internal Server Error

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; omv-salt deploy run --no-color fstab 2>&1' with exit code '100': ERROR: The state 'fstab' does not exist

"

At this point I'm getting both frustrated and desperate, since the nas itself is working just fine, the original firmware won't work due to something on the flash being corrupted, unraid seemed stable but performance wasn't all that great. So, what do I do now... I just want to mount the data volume somehow so omv can create shared folders on it, I first changed everything from /dev/dm-xx to uuids, then saved and systemctl daemon-reload to then reboot, I then removed the line the installer created and replaced it with "#UUID=688911d5-2270-4150-a71d-001de0c9e1ea /srv/disk-by-uid-688911d5-2270-4150-a71d-001de0c9e1ea xfs rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,sunit=1024,swidth=5120,noquota"

after making the propper directory on /srv ... but still nothing...

I'm not yet sure on how it could be broken, when the debian 11 system before it was omv'ed was doing just fine. It is also worth noting that all things like the volume group, the volumes themselves, as well as the /dev/md0 created by the installer, were defenately showing up in the webui after installing the lvm2 plugin and all of that. And, I could defenately change other settings without this fstab thing popping up... But, as soon as I tryed adding the data volume from within the filesystems tab, all hell just broke loose...

So, did some digging, to solve it by force rather than having the ui do it for me [and yes I know, better don't do that and all of that, but frankly there was just no other option...]

Add custom fstab options

Hi,

I'm trying to use omv in order to make easy my life with home-nas.
I have a simple question. Is a way in order to add a custom fstab option on filesystem mount?
I cannot edit directly fstab because the omv-mkconf will change losing my additions.
My problem is that the disks are born with btrfs filesystem (that I like) and I need to add a subvol=... option in order to keep the correct mounting schema.

Thanks in advance

is where I found the sollution... So, first, I created a directory under /srv with disk-by-uuid-[id], then I mounted the volume without specifying any option so that the system would figure it out, hence the long list of options you can find in

[fstab snipet]

#UUID=688911d5-2270-4150-a71d-001de0c9e1ea /srv/disk-by-uid-688911d5-2270-4150-a71d-001de0c9e1ea xfs rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,sunit=1024,swidth=5120,noquota"

Then, I just filled in all the options in the config.xml file, rebooted, et voila. I seriously wish I didn't have to mess around with the xml file, that's why there's a ui after all, but there's seemingly something between lvm's and ovm not playing along very well.

just for completeness sake:
