UnionFileSystem: set a Disk to read only

1. offizieller Beitrag

    Hi,


    i want to change a disk. Is there a way to set a disk in a UnionFileSystem to "Read only"? I want to do this with the old disk and move than all files from this disk to the UnionFilesystem.


    Greetings

    Is there a way to set a disk in a UnionFileSystem to "Read only"?

    Take the disk out of the union filesystem pool. Then copy files from it to the pool.

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

    plugins :: omvextrasorg 7.0 | kvm 7.0.13 | compose 7.1.6 | k8s 7.1.0-3 | cputemp 7.0.1 | mergerfs 7.0.4


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

    Hi,

    Yes, thats an alternate way.

    But at this way i have to take the data out of my Pool, and there runs some Docker-Containers with synced data, nextcloud, resiliosync and so on.

    So i think the better way will be to make the disk read-only. But when there is not the posibillity to do this, your way is the bester.


    So: is there a posibillity to make the disk read-only?

    No. You seemingly want the disk simultaneously writeable and non-writeable. But...


    Move your container data?


    Mount the FS allowing only docker user, ie. mount -o umask=...?


    chattr +i everything non-docker user?

    No. You seemingly want the disk simultaneously writeable and non-writeable. But...

    yes... a little bit ;)

    writeable in the omv-Filesystem, non-writeable in the UFS.


    But maybe i mount it in the omv-filesystem non-writeable and copy the data manual to the disks. What does UFS at duplicate files?
