[pbs-devel] [PATCH proxmox-backup v12 00/26] add removable datastores

[Hannes Laimer <h.laimer@proxmox.com>]

These patches add support for removable datastores. All removable
datastores have a backing-device(a UUID) associated with them. Removable
datastores work like normal ones, just that they can be unplugged. It is
possible to create a removable datastore, sync backups onto it, unplug
it and use it on a different PBS.

The datastore path specified is relative to the root of the used device.
Removable datastores are bind mounted to /mnt/datastore/<NAME>.
If we decide to allow multiple datastores on the same device in the future
they can be mounted/unmounted individually.

When a removable datastore is deleted and 'destroy-data' is set, the
device has to be mounted. If 'destroy-data' is not set the datastore
can be deleted even if the device is not present. Removable datastores
are automatically mounted when plugged in. 

v12: thanks @Wolfgang
 * use bind mounts, so now
    <DEVICE>/path/to/ds is mounted to /mnt/datastore/<NAME>
    this is a bit cleaner and allows for multiple datastores
    on a single device to be mounted individually, if we
    want to allow that in the future
 * small code improvements


v11:
 * rebase onto master

v10: thanks @Gabriel and @Wolfgang
 * make is_datastore_available more robust
 * fix a lot of wording
 * drop format on uuid_mount command for UUID
 * only gather_disk_stats if datastore is available
 * overall code improvements
 * ui: include model in partition selector
 * rebased onto master

v9:
 * change mount point to `/mnt/datastore/<name>`
 * update "Directory" list UI
 * add `absolute_path()` from Dietmar's RFC
 * update docs

v8:
 * still depends on [1]
 * paths for removable datastores are now relative to 
    `/mnt/removable_datastore/<UUID>`
 * add support for creation of removable datastore through the 
    "create directory" endpoint (last 3 patches)
 * update datastore creation UI
 * update docs

v7:
 * depends on [1]
 * improve logging when waiting for tasks
 * drop `update-datatore-cache` refactoring
 * fix some commit messages

[1] https://lists.proxmox.com/pipermail/pbs-devel/2024-April/008739.html

v6:
 * remove 'drop' flag in datastore cache
 * use maintenance-mode 'unmount' for unmounting process, only for the
    unmounting not for being unmounted
 * rename/simplify update-datastore-cache command
 * ui: integrate new unmounting maintenance mode
 * basically a mix of v3 and v4

v5: thanks @Dietmar and @Christian
 * drop --force for unmount since it'll always fail if tasks are still running, and if
    there are not normal unount will work
 * improve several commit messages
 * improve error message wording
 * add removable datastore section to docs
 * add documentation for is_datastore_available

v4: thanks a lot @Dietmar and @Christian
 * make check if mounted wayyy faster
 * don't keep track of mounting state
 * drop Unplugged maintenance mode
 * use UUID_FORMAT for uuid field
 * a lot of small things, like use of bail!, inline format!, ...
 * include improvement to cache handling

v3:
 * remove lazy unmounting (since 9cba51ac782d04085c0af55128f32178e5132358 is applied)
 * fix CLI (un)mount command, thanks @Gabriel
 * add removable datastore CLI autocomplete helper
 * rebase onto master
 * move ui patches to the end

thanks @Lukas and @Thomas for the feedback
v2:
 * fix datastore 'add' button in the UI
 * some format!("{}", a) -> format!("{a}")
 * replace `const` with `let` in js code
 * change icon `fa-usb` -> `fa-plug`
 * add some docs
 * add JDoc for parseMaintenanceMode
 * proxmox-schema dep bump
