    Hi
    btrfs-convert can convert an ext4 drive into a btrfs one, but on an unmounted drive. What's the best way to proceed with OMV? With OMV running, to force unmount from a shell (umount -force), call btrfs-convert then change drive type in /etc/config/openmediavault/config.xml ? Or do it offline by booting on a usb drive and then changing the config.xml ? What do you think about it?

    Hi
    I'm using btrfs on a dedicated drive holding lxd containers, and I am today thinking to also migrate my data and backup drives from ext4 to btrfs.
    Yet, I read several benchmarks notably those of phoronix.com (
    phoronix.com/scan.php?page=article&item=linux-50-filesystems or phoronix.com/scan.php?page=article&item=linux55-ssd-raid ) saying that btrfs and zfs were noticeably slower and something very slower than ext4.

    What's your thoughts about it? Have anyone compared between ext4 and btrfs or zfs on the speed level, notably for shared drive access and backups?
    (I know btfs and zfs offer plenty of extra features compared to ext4, I mainly wonder if there is a significant performance cost to use them versus the plain old ext4)

    Hey guys,

    I'm using a Raspberry Pi 4 (4GB) with OMV 4.1.34-1
    I have a Seagate Expansion 2,5" HDD connected via USB 3.0
    After setting up a file system and copying the files back on the HDD (from my Windows PC), the system worked a few days.
    Now the Pi disappears randomly in my network, especially when I try to copy files on the HDD.

    The Control Panel does not show the device anymore and at file system the status is "missing".

    Does anybody know what the problem is?


    p.s.: sorry for my English ;)

    Hi...I want to copy around 200Gb from an external drive to a share, which is also on a USB external drive. When I try to copy I get an error that I don't have permissions on the receiving drive. I would like to know how to set these permissions to copy from the attached drive or even from the network. I tried everything I could think of but didn't want to make a big mistake which is why I need to copy the 200Gb. I made the external drive's folder into a share thinking I could copy from there to the OVM share...but no luck. Help!! Thanks!

    Yes. Login and password are fine. Another password causes an incorrect password message. after logging in does not go further, this should be the OMV control panel.
