MergerFS.balance quesiton

1. offizieller Beitrag

    Hello all. I am using OMV 5 with mergerFS. When I set this up I set the policy to "Existing path, most free space". I am guessing you can see what happened. One disk filled up before any of the others. I have set the policy to "Most free space" now and would like to run "mergerfs.balance", which I have downloaded and installed.


    I found the id of the disk that has filled up:


    Code
    ─/dev/sdd1 ext4 Disk4 100% /srv/dev-disk-by-uuid-042bcc15-b27e-4750-9b93-67a81b9b6fd1


    I tried to run mergerfs.balance like this:


    Code
    mergerfs.balance /srv/dev-disk-by-uuid-042bcc15-b27e-4750-9b93-67a81b9b6fd1/


    And I get this error:


    Code
    /srv/dev-disk-by-uuid-042bcc15-b27e-4750-9b93-67a81b9b6fd1 is not a mergerfs mount


    What am I doing wrong please?

    Any and all help would be appreciated.


    Thank you,

    Dennis

    What am I doing wrong please?

    You are using a disk in the mergerfs pool. The following command will show you the mergerfs path(s).


    grep mergerfs /etc/fstab | awk '{ print $2 }'

    omv 7.0.5-1 sandworm | 64 bit | 6.8 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.13 | compose 7.1.4 | k8s 7.1.0-3 | cputemp 7.0.1 | mergerfs 7.0.4


    omv-extras.org plugins source code and issue tracker - github - changelogs

    Oh, ok. I ran it and see this:


    Code
    grep mergerfs /etc/fstab | awk '{ print $2 }'/srv/501bfd9a-bebf-48e5-805c-91ca31fa6f0f


    So this is the combination of the pooled drives. Thank you so much for the help.

    I ran it and got and error which I'm not sure what means:



    Any ideas on what this means or what I need to do?

    Thanks again for the help,

    It will never be able to move the aquota files. Try the following to exclude it.


    mergerfs.balance -e aquota.group /srv/501bfd9a-bebf-48e5-805c-91ca31fa6f0f/

    omv 7.0.5-1 sandworm | 64 bit | 6.8 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.13 | compose 7.1.4 | k8s 7.1.0-3 | cputemp 7.0.1 | mergerfs 7.0.4

    Same error when I ran it.

    Identical?? It shouldn't have the aquota.group file in the error. I thought it was just a copy and paste error but it should probably include listaquota.group too.


    mergerfs.balance -e aquota.group -e listaquota.group /srv/501bfd9a-bebf-48e5-805c-91ca31fa6f0f/


    If that still doesn't work, play with some of the other options here - https://github.com/trapexit/mergerfs-tools

    omv 7.0.5-1 sandworm | 64 bit | 6.8 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.13 | compose 7.1.4 | k8s 7.1.0-3 | cputemp 7.0.1 | mergerfs 7.0.4

    Thank you for the help. I ran that but still have errors. I will try some other options.



    I will post if I get it to run. Thanks again,

    Looks like you just need to add a few more files and possibly user wildcards for some of those files.

    omv 7.0.5-1 sandworm | 64 bit | 6.8 proxmox kernel

    plugins :: omvextrasorg 7.0 | kvm 7.0.13 | compose 7.1.4 | k8s 7.1.0-3 | cputemp 7.0.1 | mergerfs 7.0.4

    Hello. I tried this by adding -e aquota.user and it started working.

    Code
    mergerfs.balance -e aquota.group -e listaquota.group -e aquota.user /srv/501bfd9a-bebf-48e5-805c-91ca31fa6f0f/

    Thank you again for pointing me in the right direction.
