mergerfs - help!

k4ZzTBG7Gk · 14. September 2022

Hello,

I've successfully upgraded last night to OMV 6 (some hiccups, but overall no big issues).

Now, I've never used mergerfs before, so I wanted to pool together 2 HDDs.

They already have data on it and are referenced and have both shared folders.

Now I enable the plugin, I go to mergerfs, I put the name "pool1", then I select both drives in the filesystems (/dev/sdd1 and /dev/sda1 - both are EXT4), I leave default and apply, but I get the below error everytime.

I also tried to populate the optional fields (sharedfolders and paths, so I selected the shared folders corresponding to the drives - I have one for each drive, and in the path I put /srv/mediapool/ to have them together. Same error in red pops up:

500 - OK

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 mergerfs 2>&1' with exit code '1': pozz.nas: ---------- ID: configure_pool_dir Function: file.directory Name: /srv/mergerfs Result: True Comment: The directory /srv/mergerfs is in the correct state Started: 13:22:25.688005 Duration: 9.852 ms Changes: ---------- ID: remove_mergerfs_mount_files_/etc/systemd/system Function: module.run Result: True Comment: file.find: ['/etc/systemd/system/srv-mergerfs-pool1.mount'] Started: 13:22:25.699307 Duration: 6.71 ms Changes: ---------- file.find: - /etc/systemd/system/srv-mergerfs-pool1.mount ---------- ID: systemd_remove_dead_symlinks Function: cmd.run Name: find /etc/systemd/system/multi-user.target.wants -xtype l -print -delete Result: True Comment: Command "find /etc/systemd/system/multi-user.target.wants -xtype l -print -delete" run Started: 13:22:25.707526 Duration: 12.456 ms Changes: ---------- pid: 171762 retcode: 0 stderr: stdout: /etc/systemd/system/multi-user.target.wants/srv-mergerfs-pool1.mount ---------- ID: configure_mergerfs_pool1 Function...

Am I doing something wrong? I tried to find a tutorial on OMV6 but all I found on youtube is for OMV5

ryecoaaron · 14. September 2022

Does /srv/mediapool exist? If that is the path you are trying to mount the mergerfs pool on, you are doing it wrong. You are not able to specify the mountpoint other than the pool name. So, if you pool1 is your pool name, /srv/mergerfs/pool1 will be your mount point.

k4ZzTBG7Gk · 14. September 2022

Thanks for the reply.

Could the error be related to the fact that both disks /Media and /Media2 have inside the same folders names?

e.g. /srv/dev-disk-by-label-Media/Media/downloads and

/srv/dev-disk-by-label-Media2/Media2/downloads and can't be merged?

Do I need to rename the downloads folder?

ryecoaaron · 14. September 2022

No, I think you just have too many duplicates. You don't need to fill-in every field. Just add the follow to "Paths" and leave the filesystems and sharedfolders empty (they get converted to paths anyway).

/srv/dev-disk-by-label-Media/Media/downloads

/srv/dev-disk-by-label-Media2/Media2/downloads

k4ZzTBG7Gk · 14. September 2022

I get the same exact error. As you said maybe too many duplicates

ryecoaaron · 14. September 2022

can't read the error. If you go to the bell in the top right, it allows you to copy & paste the error instead of screenshot.

k4ZzTBG7Gk · 14. September 2022

Thanks for trying to troubleshoot this.

The error is

I think this is happening because of your previous failed attempts. Have you tried rebooting to clear those out?

k4ZzTBG7Gk · 14. September 2022

I deleted now the /srv/mergerfs/* folders and I rebooted. Same error.

I still think since both disks (Media and Media2) have inside them similar folder structure (both have dowloads/daily/movies/camera folders) with just different files, somehow mergerfs can't combine them. This my wild guess.

Otherwise my system has no errors and I never had this plugin installed before (in omv5.x).

What do you think? Any other suggestion is welcome. Should I delete the sharedfolders first?

I deleted now the /srv/mergerfs/* folders and I rebooted. Same error.

Don't do this. It will not help and you might make things worse.

Zitat von k4ZzTBG7Gk

What do you think? Any other suggestion is welcome. Should I delete the sharedfolders first?

If you have sharedfolders pointing at this pool, yes, I would delete them. I would delete this pool and try making a new one with a different name.

Thanks, I will not do this in the future. I browsed as root with filezilla, and the folder was empty (/srv/mergerfs/pool), so I deleted and rebooted.

Just to be clear, I have no sharedfolders pointing to this pool nor any other pool, as I have no active pool. I never got it to work, this is my first time attempting

What I meant were the already existing sharedfolders (Media and Media2) which are independent, standalone ext4, not in any pool.

Or they don't interfere in any way? I don't know what other thing to do, I tried with different pool name, same error pops.

Thanks.

This is my storage, I wanted mergerfs only with Media and Media2

k4ZzTBG7Gk · 14. September 2022

removed mergerfs plugin, rebooted then reinstalled it again and tried once more. No dice.

I get the same error.

What is the output of: ls -al /etc/systemd/system/*.mount

k4ZzTBG7Gk · 14. September 2022

Code

root@pozz:~# ls -al /etc/systemd/system/*.mount
-rw-r--r-- 1 root root 522 Sep 15 00:34 /etc/systemd/system/srv-mergerfs-pool1.mount
-rw-r--r-- 1 root root 289 Sep 13 14:05 /etc/systemd/system/tmp.mount

But my mergerfs section in the gui is empty.

also

Code

root@pozz:~# ls -l /srv/mergerfs/pool1
total 0

How about:

sudo rm -f /etc/systemd/system/srv-mergerfs-pool1.mount

sudo umount /srv/mergerfs/pool1

sudo systemctl daemon-reload

sudo salt-call -l debug --local --retcode-passthrough state.apply omv.deploy.mergerfs

The last command will be a lot of output. Easiest to put in text file and attach to post.

k4ZzTBG7Gk · 15. September 2022

Thanks!

Ran all your commands successfully. Last one output:

Do I try to recreate pool1?

Did you not have a pool created? If not, then try creating one preferrably with a different name.

k4ZzTBG7Gk · 15. September 2022

Unfortunately, I get the same result
