  • UUID dir created in root filesystem


    Backup plugin is setup to the second partition (/dev/sda5) of the OS drive (/dev/sda1 on /dev/sda) (I know ;) ) on which I have created a shared folder 'Sauvegardes'.

  • ZFS device(s) not listed in devices dropdown

    The fact is that this entry is remove even after boot time... I gonna test to re-add it and go to the plugin panel to see what happens...


    EDIT : Bingo ! That's it !
    On a current working conf, no reboot...
    - I copy back the ZFS pool mount section in config.xml.
    - In the GUI, move to several place, tab, etc... except ZFS panel tab. No change in config.xml.
    - In the GUI, move to ZFS panel. config.xml is modified and the ZFS pool mount section is remove...


    Done several times

  • ZFS device(s) not listed in devices dropdown

    The ZFS pool was created 2/3 weeks ago with the plugin.
    It runs nicely since without a problem since, and continue to... but something is removing the <mntent> section of the pool in config.xml. If I re-add the section in the OMV config file, all the problems are solved.
    In that case, I doubt that ZFS himself is in fault. That's something with the pluging itself or in OMV.

  • ZFS device(s) not listed in devices dropdown

    Same for me
    Disk usage tab for my ZFS pool has vanished from GUI !


    and here too
    Finding the correct mntent UUID for a filesystem not in config.xml


    There is definitively a problem with ZFS plugin or something related too, and that's not the version of the kernel...


    Check if you still have the <mntent> section of your ZFS pool in config.xml. You can copy the section back, but it will be deleted at some point... don't know by what at the moment.


  • UUID dir created in root filesystem

    Hi,


    I have just checked my / dir and saw a strange dir name some kind of UUID


    root@home-server:~# cd /
    root@home-server:/# ls -al
    total 129
    drwxr-xr-x 3 root root 4096 mars 26 17:40 ~

    I have checked the config.xml file and it's a shared folder UUID !

    Any idea why this dir is created ? If I delete it, it is recreated at some point.

  • Finding the correct mntent UUID for a filesystem not in config.xml

    From what I can see, the UUID in config.xml seems to have no link with some disk UUID at all.


    Blkid:

    Code
    /dev/sda5: LABEL="Download" UUID="2cc50fbd-d0ca-4630-8666-abcd673cb0ac" TYPE="ext4" PARTUUID="6e22f66d-05"


    config.xml


    Code
    <mntent>

            <uuid>a6b1d550-c75f-484b-a8e5-1ee12f860450</uuid>

            <fsname>/dev/disk/by-id/ata-SAMSUNG_MZ7LN512HCHP-000L1_S1ZKNXAG526958-part5</fsname>

            <dir>/srv/dev-disk-by-id-ata-SAMSUNG_MZ7LN512HCHP-000L1_S1ZKNXAG526958-part5</dir>

            <type>ext4</type>

            <opts>defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,discard,acl</opts>

            <passno>2</passno>

            <hidden>0</hidden>

          </mntent>


    I think it is just a random UUID. But it needs to be referenced by each <sharefolder>/<mntentref> to link those two.

  • OMV on desktop computer. What about the drivers??

    That's standard hardware with intel Core processor and Lan. There should be no problem with it. Don't know what is the audio chipset (why audio in a NAS !??? lol) but I assume that it will be too, as Linux have a good driver support nowadays.
    Go on, there should be no problem with it.

  • Finding the correct mntent UUID for a filesystem not in config.xml

    Hi,


    I think that for a reason or another, I have the same problem here, as my pool is continuously deleted from the config.xml file.


    Disk usage tab for my ZFS pool has vanished from GUI !


  • Disk usage tab for my ZFS pool has vanished from GUI !

    Unfortunatly, Something is still modifying my config.xml file... and deleting the ZFS pool from it !


    Any idea what can do this ?


    Thx

  • Disk usage tab for my ZFS pool has vanished from GUI !

    Hi SubZero,


    I managed to get my IO stats from the disks of the ZFS pool by using the DiskMgmt/enumerateDevices function in place of FileSystemMgmt/enumerateMountedFilesystems. That works. I'm having the raw stats and not the ZFS iostat results. But that enough for me ATM. The sad thing is that I must be careful at each OMV update as I "updated" 2 or 3 js scripts that would be overwriten... :(



    Volker told me that this function enumerates also the USB disks (plug in and out), so as I'm not using any on the NAS (only USB 2 ports against PC USB 3 + gigabyte network is more efficient), that is a good solution for me.


    I also added some temperature graph on the CPU. I searching a way to have my 2 cores on the same tab, as I have discovered that only the cpu-0 core is displayed, even if you have the datas from all your CPU cores. I have almost found, but it need some GUI tweaks (I'm not good at this :( ).


    I would like to participate in the plugin dev, but from what I have seens the last 2 days, my level is poor with the OMV "Framework". I'm a sys admin, used to be a dev 15 years ago... helped to dev some of the v0.2/0.3 plugins (greyhole, etc...) but it's hard to understand the Framework details.


    From my point of view, and I'm really new to ZFS (3 weeks !), that a really good file system. I was using mdadm/ext4 before but the checksum/snapshots features are really a must have. I managed to find some "silent corruptions" on video files with it.
    More and more NAS OS are using ZFS for data pools (e.g.: MyNAS, etc...), as you can have encryption, deduplication, compression, multiple copies of files natively...
    This should be the default FS for data pool in OMV inn my opinion. Ext4+mdadm+lvm works nice, but you need to manage 3 piece of software to do the same. So let's try to keep this plugin alive, as it is the future of FS storage ;)

    Quote from ryecoaaron

    Here is the function - https://github.com/openmediava…c/filesystemmgmt.inc#L166
    It returns this array for each filesystem - https://github.com/openmediava…c/filesystemmgmt.inc#L221


    You could change this function on a test machine. As long as it returned the array with the proper structure, it should keep working.

    I have tried to replace this one with that one as it seems that only the devicename result is used.

    Unfortunatly, that doesn't works.


    Any idea why ?


    EDIT: Found. The first return 'parentdevicefile' and the second 'devicefile'.
    Yeah baby. It works, but it would be scratched by the next OMV update :(

  • Disk usage tab for my ZFS pool has vanished from GUI !

    So...


    On one hand, this morning, I copied back another time the save config file and reboot the server just after.
    Problem seems to be gone !


    I still don't know what was keeping modifing my config file... but it "seems" to be gone.




    On another hand, I was asking myself why the DiskIO.js in the diskstats pluging is using the "mounted" disks to generate the UI for the I/O graph.
    You don't have to have a disk mounted in/by OMV to check the I/O and throughputs (e.g. ZFS disk are not mounted by OMV but it's nice to have some read/write infos on them !)
    Maybe the diskstat plugin need a little improvment...


    Cheers,

  • Disk usage tab for my ZFS pool has vanished from GUI !

    OK !


    For whatever reason, the ZFS pool mount entry have disapeared from OMV config file !!!
    Don't know why or what happens.


    Luckily, with the OMV backup plugin, I had a backup of the file at last friday's evening, and manage to copy back the right section of conf the the file, and then the graph is showing back.


    EDIT: Gone another time several minutes after the edit... something is writing in the config.xml file and removing the ZFS pool mount point...


    Sometimes, computers makes me mad :(


  • Disk usage tab for my ZFS pool has vanished from GUI !

    aybe the best way is to "add" a mount point in OMV config.xml file... as it is a mountpoint !


    I don't know if there is some side effect to have a mount point in config.xml without the corresponding line in /etc/fstab ?


    EDIT: I have just setup a fresh VM with OMV + ZFS plugin and the tab entry is here !!!

    Aaron,


    Maybe you could help me.


    How can I check what is returned by this call, and which format is it ?
    how can I replace this code with static one to do some tests ?


    DiskIO.js near line 90:
