What version of mergerfs?

Quote

joel@dunder:~$ mergerfs -v
mergerfs version: 2.9.1
FUSE library version: 2.9.5
fusermount version: 2.9.5
using FUSE kernel interface version 7.19

(fuse and libfuse backported from sid because of bug in libfuse 2.9.0 which made libfuse segfault)

@jkaberg

Can you explain me how to backport fuse and libfuse from sid ?
I have tried it with this tutorial (https://wiki.debian.org/SimpleBackportCreation)

But all i get is this: VALIDATION FAILED!!

Thanks !

Because of the same problems he had, fuse segfaults ...

Good Evening Lads,

hope you don't mind if im hooking in.

Since a few days i encounter a lot of problems with aufs, when renaming Folders by SMB or WINSCP.

As i've seen this is normal although i never realized it

What would be the best procedure to "migrate" from aufs ( old aufs plugin ) to mergerfs ?

My idea was to first create with mergerfs a new pool, then MOVE all files inside the "Aufs branch shares" - otherwise if i delete the shares, the data will be lost - into the new mergerfs pool folder and set new shares.

Would this be the best and easiest way ?

Im a little worried as i want to move in total 24TB and i have no backup plan

I have installed aufs through the old AUFS Plugin and not through Unionfilesyste. Guess therefore i cannot just switch the plugin ?!? Or am I wrong ?

You know, never change a running system, so there was no need to uninstall the old AUFS before.

But im still unsure, as with the old aufs you had to create the shares manually and when you just delete Aufs and the shares my data would be gone.

So i guess i have to do it like this : My idea was to first create with mergerfs a new pool, then MOVE all files inside the "Aufs branch shares" - otherwise if i delete the shares, the data will be lost - into the new mergerfs pool folder and set new shares

Correct ?

Deleting the share doesn't mean deleting the data, it's just a reference in the GUI, you don't actually delete the data. At least you will be asked wether or not to delete the data.

OMG...the last times i've clicked too fast and deleted the share and the data.... -> IDIOT is me

One last question, now that i have uninstalled aufs there are a lot Folders and files left looking like:

Can i delete them ?https://picload.org/image/wlpccoa/.wh.folder.jpg

Hey guys,

had a problem with my server. Yesterday I started a rebuild, changed the OS from SLC-USB-Stick (Mach Xtreme Technology MX-ES 8GB) to SSD (120 GB Samsung EVO 850). Repartioned the SSD after installation, OS is now 20 GB, remaining 80 GB shall be used later for Plex-DB. Before I have to copy my backup I made a small test, I think I made something wrong.

Okay, next step was to recreate the pool. I disconnected the data disks and plugged two old 1 TB disks inside to make a test.

I used follwing configuration:

1 * parity disk 4 TiB
2 * data disk 1 TiB

Usually I expected a pool around 1,8 TiB, but the GUI showed me something around 5,38 TiB. It looks like a JBOD, doesn´t it?

When I created the pool inside the OMV-GUI I marked the disks as followed:

1 * 4 TiB content and parity
2 * 2 TiB content and data

Next step was to copy some files to the pool via network, successful. I expected the files on the data disks, but they are on the parity disk.

Tried a sync, answer was "everything fine, nothing to do"

I think, I should remark content on the parity disk. Will do that today evening. What do recommend for the pooling, aufs or mergerfs?

Thanks for your help.

Thanks for response, man.

Will give it a try. What about my config? I think, I have to change the setting for the parity disk to "parity" only, right?

Followed the Snapraid-Guide on the german website http://www.technikaffe.de/anle…itung_fuer_openmediavault

Take a look on the last pic in section 6. I think, this is not correct.

Peter

Looks allright to me, where is your confusion?

Greetings
David

Usually the parity disk contains only parity data, no files, right? Data is usually stored on the data disks.

That´s my confusion.

In my old config all the data disks were filled, and not the parity disk.

I explained, that my data (around 300 GiB of movies, music etc) is now only stored on the parity disk, the data disks are empty.

Am I completely wrong?
